We look at the division of 877848 by 57 
We want to divide 877848 by 57.

On to step 1:
The number 57 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 57

Going ahead to step 2:
87 divided by 57 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 57 from 87 to get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 57

Going ahead to step 3:
57 can be fit into 307 5 times, resulting in a remainder of 22.
The next digit of our result is 5. 
Result so far: 15.0
If we take 285 away from 307, we end up with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 57

Let's proceed to step 4:
The number 57 fits into 228 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 228 from 228 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 57

Advancing to step 5:
4 divided by 57 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1540.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 57

Let's proceed to step 6:
57 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 15400.0
Deduct 0 from 48 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15400.8
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
The number 57 fits into 240 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15400.84
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
57 can be fit into 120 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 15400.842
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
57 goes into 60 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 15400.8421
If we take 57 away from 60, 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 11:
57 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15400.8421
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
57 can be fit into 300 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 15400.842105
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.

Step 13:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 15400.8421052
Subtract 114 from 150 to get 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 14:
360 divided by 57 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 15400.84210526
Deduct 342 from 360 and we're left 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.

The final outcome is 15400.84210526, with a leftover of 1.8e-08.
