We look at the division of 28751586 by 661 
We want to divide 28751586 by 661.

Step 1:
If we divide 2 by 661, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 661

Step 2:
If we divide 28 by 661, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 661

Step 3:
287 divided by 661 is 0 with a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 287 to get 287.
Include the next digit (5) from the dividend after 287, then repeat: 2875 / 661

Advancing to step 4:
661 can be fit into 2875 4 times, resulting in a remainder of 231.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2644 away from 2875, we end up with 231.
Bring next digit (1) of the dividend behind the 231 and repeat the process: 2311 / 661

Moving on to step 5:
When dividing 2311 by 661, we get 3 with a remainder of 328.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 328 after subtracting 1983 from 2311.
Grab the next digit (5) from the dividend, add it to 328, then carry on: 3285 / 661

Step 6:
If we divide 3285 by 661, we get 4 and a remainder of 641.
The next digit of our result is 4. 
Result so far: 434.0
Subtract 2644 from 3285 to get 641.
Grab the next digit (8) from the dividend, add it to 641, then carry on: 6418 / 661

Advancing to step 7:
The number 661 fits into 6418 9 times, leaving a remainder of 469.
Put 9 as the next digit of the answer. 
Result so far: 4349.0
If we take 5949 away from 6418, we end up with 469.
Append the next digit (6) from the dividend to 469 and continue with: 4696 / 661

On to step 8:
4696 divided by 661 is 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 43497.0
Subtract 4627 from 4696 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
The number 661 fits into 690 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 43497.1
Subtracting 661 from 690 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
661 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 43497.1
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 11:
661 goes into 2900 4 times with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 43497.104
If we take 2644 away from 2900, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
661 can be fit into 2560 3 times, resulting in a remainder of 577.
Use 3 as the next digit of our solution. 
Result so far: 43497.1043
Subtract 1983 from 2560 to get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 13:
If we divide 5770 by 661, we get 8 and a remainder of 482.
The next digit of our result is 8. 
Result so far: 43497.10438
Deduct 5288 from 5770 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 14:
When dividing 4820 by 661, we get 7 with a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 43497.104387
Subtract 4627 from 4820 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 15:
661 can be fit into 1930 2 times, resulting in a remainder of 608.
Record the quotient 2 as the next digit in the result. 
Result so far: 43497.1043872
The remainder is 608 after subtracting 1322 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 16:
If we divide 6080 by 661, we get 9 and a remainder of 131.
The next digit of our result is 9. 
Result so far: 43497.10438729
Subtract 5949 from 6080 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

In conclusion, the division gives 43497.10438729 with a balance of 1.31e-07.
