We look at the division of 39892355 by 457 
We want to figure out the number of times 39892355 can be divided by 457.

Going ahead to step 1:
When dividing 3 by 457, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 457

Let's proceed to step 2:
457 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 457

Let's proceed to step 3:
When dividing 398 by 457, we get 0 with a remainder of 398.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Append the next digit (9) from the dividend to 398 and continue with: 3989 / 457

Step 4:
If we divide 3989 by 457, we get 8 and a remainder of 333.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 3656 from 3989 to get 333.
Grab the next digit (2) from the dividend, add it to 333, then carry on: 3332 / 457

On to step 5:
3332 divided by 457 is 7 with a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 3199 away from 3332, we end up with 133.
Bring next digit (3) of the dividend behind the 133 and repeat the process: 1333 / 457

Going ahead to step 6:
457 can be fit into 1333 2 times, resulting in a remainder of 419.
Use 2 as the next digit of our solution. 
Result so far: 872.0
Subtracting 914 from 1333 leaves us with 419.
Append the next digit (5) from the dividend to 419 and continue with: 4195 / 457

Let's proceed to step 7:
457 goes into 4195 9 times with a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 8729.0
Subtract 4113 from 4195 to get 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 457

On to step 8:
The number 457 fits into 825 1 times, leaving a remainder of 368.
The next digit of our result is 1. 
Result so far: 87291.0
The remainder is 368 after subtracting 457 from 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
The number 457 fits into 3680 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 87291.8
Subtracting 3656 from 3680 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
457 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 87291.8
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
2400 divided by 457 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 87291.805
Subtracting 2285 from 2400 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 12:
The number 457 fits into 1150 2 times, leaving a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 87291.8052
The remainder is 236 after subtracting 914 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 13:
The number 457 fits into 2360 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 87291.80525
If we take 2285 away from 2360, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
457 can be fit into 750 1 times, resulting in a remainder of 293.
Record the quotient 1 as the next digit in the result. 
Result so far: 87291.805251
Subtract 457 from 750 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 15:
The number 457 fits into 2930 6 times, leaving a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 87291.8052516
Subtract 2742 from 2930 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 16:
The number 457 fits into 1880 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 87291.80525164
Subtracting 1828 from 1880 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 87291.80525164, with a leftover of 5.2e-08.
