Hey there!
To solve 414÷3=c, you must simplify the expression to set c equal to a value.
To divide this expression, 414÷3, first see if your divisor, 3 can go into the 400 in 414. Because 3 can go into it 100 times at most, you would put a 1 in the hundreds place.
Now, since 1*3 is 3, subtract 3 from the 4 in the hundreds place (or previously referred to as 400).
This will get you to 1 and now bring down the next value, 10 or the 1 value in the tens place of 414 so you now have 11.
Now, find out how many times 3 can multiply into 11 without going over. This would be 3, so you would put a 3 in the tens place. Because, 3*3 is 9 you would subtract 9 from 11 to get 2.
Now, bring down the final digit, 4 next to the 2 you previously had. You now have 24. Then, find out how many times 3 can go into 24. This would be 8 so you would put 8 in your ones place. Because 3 goes into 24 8 times without any remainders, your final answer would be 138.
The work is down below in case you would like to visually see my explanation.
Therefore, your final answer would be that c=138. :)
