We look at the division of 485509 by 57 
We're looking to find how many times 57 goes into 485509.

Step 1:
When dividing 4 by 57, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 57

Going ahead to step 2:
When dividing 48 by 57, we get 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 57

Going ahead to step 3:
57 can be fit into 485 8 times, resulting in a remainder of 29.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 456 from 485 to get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 57

Going ahead to step 4:
If we divide 295 by 57, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 285 from 295, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 57

On to step 5:
If we divide 100 by 57, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 851.0
Subtracting 57 from 100 leaves us with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 57

Step 6:
When dividing 439 by 57, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 8517.0
Subtracting 399 from 439 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
57 can be fit into 400 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 8517.7
If we subtract 399 from 400, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 57 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8517.7
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
57 can be fit into 100 1 times, resulting in a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 8517.701
If we take 57 away from 100, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
430 divided by 57 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 8517.7017
Subtract 399 from 430 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
If we divide 310 by 57, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8517.70175
Deduct 285 from 310 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
The number 57 fits into 250 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 8517.701754
Deduct 228 from 250 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
57 can be fit into 220 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 8517.7017543
Subtracting 171 from 220 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
If we divide 490 by 57, we get 8 and a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 8517.70175438
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 8517.70175438 with a remaining 3.4e-08.
