Let's divide 668745 by 57
Let's see how many times 57 fits into 668745.

Going ahead 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
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 57

Going ahead to step 2:
The number 57 fits into 66 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 57 from 66 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 57

Going ahead 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
If we subtract 57 from 98, we get 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 57

Moving on to step 4:
If we divide 417 by 57, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 399 away from 417, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 57

Going ahead to step 5:
The number 57 fits into 184 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
The remainder is 13 after subtracting 171 from 184.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 57

Going ahead to step 6:
135 divided by 57 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 11732.0
Subtract 114 from 135 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
210 divided by 57 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 11732.3
If we subtract 171 from 210, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
390 divided by 57 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11732.36
The remainder is 48 after subtracting 342 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 11732.368
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 57, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 11732.3684
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
57 goes into 120 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 11732.36842
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
60 divided by 57 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11732.368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 57 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11732.368421
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
57 goes into 300 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11732.36842105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 11732.36842105, with a leftover of 1.5e-08.
