28669137 divided by 660 
We want to figure out the number of times 28669137 can be divided by 660.

Advancing to step 1:
If we divide 2 by 660, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 660

Step 2:
When dividing 28 by 660, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 660

Let's proceed to step 3:
If we divide 286 by 660, we get 0 and a remainder of 286.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 286 after subtracting 0 from 286.
Bring next digit (6) of the dividend behind the 286 and repeat the process: 2866 / 660

Step 4:
2866 divided by 660 is 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2640 from 2866, we get 226.
Include the next digit (9) from the dividend after 226, then repeat: 2269 / 660

Going ahead to step 5:
When dividing 2269 by 660, we get 3 with a remainder of 289.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 1980 from 2269 leaves us with 289.
Grab the next digit (1) from the dividend, add it to 289, then carry on: 2891 / 660

Moving on to step 6:
660 can be fit into 2891 4 times, resulting in a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Deduct 2640 from 2891 and we're left with 251.
Include the next digit (3) from the dividend after 251, then repeat: 2513 / 660

Going ahead to step 7:
660 goes into 2513 3 times with a remainder of 533.
Use 3 as the next digit of our solution. 
Result so far: 4343.0
Subtract 1980 from 2513 to get 533.
Bring next digit (7) of the dividend behind the 533 and repeat the process: 5337 / 660

On to step 8:
The number 660 fits into 5337 8 times, leaving a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 43438.0
The remainder is 57 after subtracting 5280 from 5337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
660 can be fit into 570 0 times, resulting in a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 43438.0
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
660 goes into 5700 8 times with a remainder of 420.
Write down 8 as next digit of the result. 
Result so far: 43438.08
Subtracting 5280 from 5700 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
When dividing 4200 by 660, we get 6 with a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 43438.086
Subtract 3960 from 4200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
660 goes into 2400 3 times with a remainder of 420.
Put 3 as the next digit of the answer. 
Result so far: 43438.0863
Deduct 1980 from 2400 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 13:
660 goes into 4200 6 times with a remainder of 240.
The next digit of our result is 6. 
Result so far: 43438.08636
If we take 3960 away from 4200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
The number 660 fits into 2400 3 times, leaving a remainder of 420.
Use 3 as the next digit of our solution. 
Result so far: 43438.086363
Subtracting 1980 from 2400 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 15:
4200 divided by 660 is 6 with a remainder of 240.
The next digit of our result is 6. 
Result so far: 43438.0863636
Subtract 3960 from 4200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
When dividing 2400 by 660, we get 3 with a remainder of 420.
Write down 3 as next digit of the result. 
Result so far: 43438.08636363
Deduct 1980 from 2400 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Our division results in 43438.08636363 with a remaining 4.2e-07.
