We're dividing 668857 by 57 
We want to divide 668857 by 57.

Let's proceed to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 57

Let's proceed to step 2:
The number 57 fits into 66 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 57 from 66 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 57

On to step 3:
57 goes into 98 1 times with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 41 after subtracting 57 from 98.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 57

On to step 4:
418 divided by 57 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we take 399 away from 418, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 57

Advancing to step 5:
If we divide 195 by 57, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 1173.0
Subtract 171 from 195 to get 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 57

Step 6:
When dividing 247 by 57, we get 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 11734.0
If we take 228 away from 247, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
57 goes into 190 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 11734.3
If we subtract 171 from 190, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
57 can be fit into 190 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 11734.33
The remainder is 19 after subtracting 171 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 11734.33, and the remainder is 0.019.
