We're dividing 869783 by 57 
Our goal is to divide 869783 by 57.

Let's proceed to step 1:
57 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 57

Step 2:
86 divided by 57 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 57 from 86 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 57

Going ahead to step 3:
When dividing 299 by 57, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 285 from 299, we get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 57

Going ahead to step 4:
The number 57 fits into 147 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we take 114 away from 147, we end up with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 57

Advancing to step 5:
57 can be fit into 338 5 times, resulting in a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 1525.0
If we subtract 285 from 338, we get 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 57

Moving on to step 6:
If we divide 533 by 57, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 15259.0
Subtracting 513 from 533 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
57 can be fit into 200 3 times, resulting in a remainder of 29.
The next digit of our result is 3. 
Result so far: 15259.3
If we take 171 away from 200, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
57 can be fit into 290 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15259.35
If we subtract 285 from 290, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
57 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 15259.35
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 57 fits into 500 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 15259.3508
Subtract 456 from 500 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
If we divide 440 by 57, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 15259.35087
If we take 399 away from 440, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
The number 57 fits into 410 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 15259.350877
Deduct 399 from 410 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 15259.350877, and the remainder is 1.1e-06.
