We divide 870861 by 57
We want to figure out the number of times 870861 can be divided by 57.

Let's proceed to step 1:
57 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 57

On to step 2:
57 can be fit into 87 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 30 after subtracting 57 from 87.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 57

Advancing to step 3:
57 goes into 300 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 285 from 300, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 57

Going ahead to step 4:
158 divided by 57 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 114 from 158, we get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 57

Going ahead to step 5:
When dividing 446 by 57, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 1527.0
Subtracting 399 from 446 leaves us with 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 57

Advancing to step 6:
57 goes into 471 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 15278.0
Subtracting 456 from 471 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 57, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 15278.2
If we take 114 away from 150, we end up 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.

Advancing to step 8:
The number 57 fits into 360 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 15278.26
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 57, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 15278.263
If we subtract 171 from 180, we get 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 10:
When dividing 90 by 57, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 15278.2631
The remainder is 33 after subtracting 57 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
57 can be fit into 330 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 15278.26315
Deduct 285 from 330 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
When dividing 450 by 57, we get 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 15278.263157
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.

On to step 13:
57 goes into 510 8 times with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 15278.2631578
Deduct 456 from 510 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
The number 57 fits into 540 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 15278.26315789
If we take 513 away from 540, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 15278.26315789, and the remainder is 2.7e-08.
