We're dividing 39379337 by 457 
We want to divide 39379337 by 457.

Step 1:
3 divided by 457 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 457

Moving on to step 2:
457 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 457

Step 3:
The number 457 fits into 393 0 times, leaving a remainder of 393.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 393 leaves us with 393.
Include the next digit (7) from the dividend after 393, then repeat: 3937 / 457

Going ahead to step 4:
If we divide 3937 by 457, we get 8 and a remainder of 281.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 3656 from 3937 to get 281.
Fetch the next digit (9) from the dividend, attach it to 281 and continue: 2819 / 457

Going ahead to step 5:
If we divide 2819 by 457, we get 6 and a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 2742 from 2819, we get 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 457

Going ahead to step 6:
If we divide 773 by 457, we get 1 and a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
Subtract 457 from 773 to get 316.
Fetch the next digit (3) from the dividend, attach it to 316 and continue: 3163 / 457

Going ahead to step 7:
The number 457 fits into 3163 6 times, leaving a remainder of 421.
Put 6 as the next digit of the answer. 
Result so far: 8616.0
Subtract 2742 from 3163 to get 421.
Bring next digit (7) of the dividend behind the 421 and repeat the process: 4217 / 457

Moving on to step 8:
When dividing 4217 by 457, we get 9 with a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 86169.0
The remainder is 104 after subtracting 4113 from 4217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
457 can be fit into 1040 2 times, resulting in a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 86169.2
If we subtract 914 from 1040, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 10:
1260 divided by 457 is 2 with a remainder of 346.
Record the quotient 2 as the next digit in the result. 
Result so far: 86169.22
Subtract 914 from 1260 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

The final result is 86169.22 with a remainder of 0.346.
