Let's divide 28737988 by 991
Our goal is to divide 28737988 by 991.

Moving on to step 1:
991 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 991

Advancing to step 2:
When dividing 28 by 991, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 991

On to step 3:
If we divide 287 by 991, we get 0 and 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 (3) from the dividend after 287, then repeat: 2873 / 991

Going ahead to step 4:
991 goes into 2873 2 times with a remainder of 891.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1982 from 2873 and we're left with 891.
Grab the next digit (7) from the dividend, add it to 891, then carry on: 8917 / 991

On to step 5:
When dividing 8917 by 991, we get 8 with a remainder of 989.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 7928 away from 8917, we end up with 989.
Include the next digit (9) from the dividend after 989, then repeat: 9899 / 991

Moving on to step 6:
991 goes into 9899 9 times with a remainder of 980.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
The remainder is 980 after subtracting 8919 from 9899.
Grab the next digit (8) from the dividend, add it to 980, then carry on: 9808 / 991

Step 7:
When dividing 9808 by 991, we get 9 with a remainder of 889.
Record the quotient 9 as the next digit in the result. 
Result so far: 2899.0
Subtracting 8919 from 9808 leaves us with 889.
Grab the next digit (8) from the dividend, add it to 889, then carry on: 8898 / 991

Moving on to step 8:
If we divide 8898 by 991, we get 8 and a remainder of 970.
Put 8 as the next digit of the answer. 
Result so far: 28998.0
Deduct 7928 from 8898 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

Let's proceed to step 9:
When dividing 9700 by 991, we get 9 with a remainder of 781.
Use 9 as the next digit of our solution. 
Result so far: 28998.9
Subtracting 8919 from 9700 leaves us with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Advancing to step 10:
991 can be fit into 7810 7 times, resulting in a remainder of 873.
Use 7 as the next digit of our solution. 
Result so far: 28998.97
Subtract 6937 from 7810 to get 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

Moving on to step 11:
8730 divided by 991 is 8 with a remainder of 802.
Write down 8 as next digit of the result. 
Result so far: 28998.978
Subtract 7928 from 8730 to get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 12:
991 goes into 8020 8 times with a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 28998.9788
If we take 7928 away from 8020, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 28998.9788 with a remainder of 0.00092.
