We look at the division of 639785 by 57 
We're looking to find how many times 57 goes into 639785.

Moving on to step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 57

Step 2:
63 divided by 57 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 57 from 63 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 57

Step 3:
57 can be fit into 69 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 57 from 69, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 57

Advancing to step 4:
If we divide 127 by 57, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 114 away from 127, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 57

Advancing to step 5:
The number 57 fits into 138 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1122.0
The remainder is 24 after subtracting 114 from 138.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 57

On to step 6:
If we divide 245 by 57, we get 4 and a remainder of 17.
The next digit of our result is 4. 
Result so far: 11224.0
Subtracting 228 from 245 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 57 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 11224.2
Subtracting 114 from 170 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
57 can be fit into 560 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 11224.29
The remainder is 47 after subtracting 513 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
57 can be fit into 470 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 11224.298
Subtract 456 from 470 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
57 goes into 140 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 11224.2982
Deduct 114 from 140 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 57 fits into 260 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 11224.29824
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 57, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11224.298245
Subtracting 285 from 320 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
If we divide 350 by 57, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 11224.2982456
If we take 342 away from 350, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
The number 57 fits into 80 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 11224.29824561
If we take 57 away from 80, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 11224.29824561 with a remaining 2.3e-08.
