We divide 668401 by 57
Our goal is to divide 668401 by 57.

Moving on to step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 57

Advancing to step 2:
If we divide 66 by 57, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 57 away from 66, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 57

Let's proceed to step 3:
The number 57 fits into 98 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 57 from 98 and we're left with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 57

Let's proceed to step 4:
When dividing 414 by 57, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 399 from 414 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 57

Moving on to step 5:
If we divide 150 by 57, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1172.0
Subtracting 114 from 150 leaves us with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 57

Going ahead to step 6:
361 divided by 57 is 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 11726.0
Deduct 342 from 361 and we're left 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.

Let's proceed to step 7:
The number 57 fits into 190 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 11726.3
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.

Let's proceed to step 8:
57 goes into 190 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 11726.33
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.

After the division, we end up with 11726.33 and a remainder of 0.019.
