28491861 divided by 997 
We want to figure out the number of times 28491861 can be divided by 997.

On to step 1:
997 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
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 / 997

Step 2:
28 divided by 997 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 997

Going ahead to step 3:
When dividing 284 by 997, we get 0 with a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 997

Step 4:
997 can be fit into 2849 2 times, resulting in a remainder of 855.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1994 from 2849 to get 855.
Grab the next digit (1) from the dividend, add it to 855, then carry on: 8551 / 997

Moving on to step 5:
The number 997 fits into 8551 8 times, leaving a remainder of 575.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 7976 from 8551, we get 575.
Append the next digit (8) from the dividend to 575 and continue with: 5758 / 997

Advancing to step 6:
The number 997 fits into 5758 5 times, leaving a remainder of 773.
The next digit of our result is 5. 
Result so far: 285.0
If we take 4985 away from 5758, we end up with 773.
Fetch the next digit (6) from the dividend, attach it to 773 and continue: 7736 / 997

Let's proceed to step 7:
7736 divided by 997 is 7 with a remainder of 757.
Write down 7 as next digit of the result. 
Result so far: 2857.0
Deduct 6979 from 7736 and we're left with 757.
Fetch the next digit (1) from the dividend, attach it to 757 and continue: 7571 / 997

Advancing to step 8:
997 goes into 7571 7 times with a remainder of 592.
Use 7 as the next digit of our solution. 
Result so far: 28577.0
If we take 6979 away from 7571, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 9:
5920 divided by 997 is 5 with a remainder of 935.
The number 5 becomes the next digit in our result. 
Result so far: 28577.5
If we subtract 4985 from 5920, we get 935.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9350, and continue the process.

Step 10:
997 can be fit into 9350 9 times, resulting in a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 28577.59
Subtracting 8973 from 9350 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 11:
When dividing 3770 by 997, we get 3 with a remainder of 779.
The next digit of our result is 3. 
Result so far: 28577.593
Subtract 2991 from 3770 to get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Moving on to step 12:
7790 divided by 997 is 7 with a remainder of 811.
Record the quotient 7 as the next digit in the result. 
Result so far: 28577.5937
Subtracting 6979 from 7790 leaves us with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Advancing to step 13:
When dividing 8110 by 997, we get 8 with a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 28577.59378
The remainder is 134 after subtracting 7976 from 8110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 14:
1340 divided by 997 is 1 with a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 28577.593781
If we take 997 away from 1340, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 15:
If we divide 3430 by 997, we get 3 and a remainder of 439.
The next digit of our result is 3. 
Result so far: 28577.5937813
If we subtract 2991 from 3430, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 16:
The number 997 fits into 4390 4 times, leaving a remainder of 402.
Put 4 as the next digit of the answer. 
Result so far: 28577.59378134
If we take 3988 away from 4390, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

After the division, we end up with 28577.59378134 and a remainder of 4.02e-07.
