864978 divided by 57 
We want to figure out the number of times 864978 can be divided by 57.

Step 1:
8 divided by 57 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 57

On to step 2:
The number 57 fits into 86 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 57 away from 86, we end up with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 57

Advancing to step 3:
294 divided by 57 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 9 after subtracting 285 from 294.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 57

Moving on to step 4:
If we divide 99 by 57, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Subtract 57 from 99 to get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 57

Step 5:
The number 57 fits into 427 7 times, leaving a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 1517.0
If we take 399 away from 427, we end up with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 57

Advancing to step 6:
288 divided by 57 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15175.0
If we take 285 away from 288, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 57 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15175.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 57, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15175.05
The remainder is 15 after subtracting 285 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 15175.052
Deduct 114 from 150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
57 can be fit into 360 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 15175.0526
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 57, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 15175.05263
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
57 can be fit into 90 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 15175.052631
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
The number 57 fits into 330 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 15175.0526315
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
57 can be fit into 450 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 15175.05263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 15175.05263157, with a leftover of 5.1e-08.
