We're dividing 660631 by 28 
We want to divide 660631 by 28.

Moving on to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 28

Let's proceed to step 2:
66 divided by 28 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 56 from 66, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 28

Step 3:
100 divided by 28 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 16 after subtracting 84 from 100.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 28

Going ahead to step 4:
When dividing 166 by 28, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Subtract 140 from 166 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 28

Step 5:
263 divided by 28 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 2359.0
Subtracting 252 from 263 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 28

Going ahead to step 6:
The number 28 fits into 111 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 23593.0
Deduct 84 from 111 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
28 can be fit into 270 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 23593.9
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 28, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 23593.96
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 23593.964
Subtracting 112 from 120 leaves us 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.

Advancing to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 23593.9642
If we take 56 away from 80, we end up 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.

Going ahead to step 11:
240 divided by 28 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 23593.96428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 23593.964285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 23593.9642857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 23593.96428571
Subtracting 28 from 40 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.

In conclusion, the division gives 23593.96428571 with a balance of 1.2e-08.
