We're dividing 853821 by 57 
Let's see how many times 57 fits into 853821.

Moving on to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 57

Advancing to step 2:
If we divide 85 by 57, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 85, we get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 57

On to step 3:
57 can be fit into 283 4 times, resulting in a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 228 from 283, we get 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 57

Going ahead to step 4:
The number 57 fits into 558 9 times, leaving a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 513 from 558 to get 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 57

Going ahead to step 5:
452 divided by 57 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 1497.0
Deduct 399 from 452 and we're left with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 57

Step 6:
531 divided by 57 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 14979.0
Subtract 513 from 531 to 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.

Step 7:
If we divide 180 by 57, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 14979.3
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.

Going ahead to step 8:
When dividing 90 by 57, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 14979.31
If we take 57 away from 90, we end up 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 9:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 14979.315
Subtract 285 from 330 to get 45.
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 10:
450 divided by 57 is 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 14979.3157
If we take 399 away from 450, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
The number 57 fits into 510 8 times, leaving a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 14979.31578
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
540 divided by 57 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 14979.315789
The remainder is 27 after subtracting 513 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
57 goes into 270 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 14979.3157894
Deduct 228 from 270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
420 divided by 57 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 14979.31578947
Deduct 399 from 420 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 14979.31578947 and a remainder of 2.1e-08.
