We look at the division of 18991025 by 990 
We want to figure out the number of times 18991025 can be divided by 990.

Moving on to step 1:
990 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 990

Advancing to step 2:
If we divide 18 by 990, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 990

On to step 3:
189 divided by 990 is 0 with a remainder of 189.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 189 and we're left with 189.
Take the next digit (9) from the dividend and append it to 189, then repeat: 1899 / 990

Going ahead to step 4:
990 can be fit into 1899 1 times, resulting in a remainder of 909.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 909 after subtracting 990 from 1899.
Include the next digit (1) from the dividend after 909, then repeat: 9091 / 990

On to step 5:
9091 divided by 990 is 9 with a remainder of 181.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 181 after subtracting 8910 from 9091.
Fetch the next digit (0) from the dividend, attach it to 181 and continue: 1810 / 990

Moving on to step 6:
If we divide 1810 by 990, we get 1 and a remainder of 820.
The next digit of our result is 1. 
Result so far: 191.0
If we subtract 990 from 1810, we get 820.
Bring next digit (2) of the dividend behind the 820 and repeat the process: 8202 / 990

Moving on to step 7:
990 can be fit into 8202 8 times, resulting in a remainder of 282.
Use 8 as the next digit of our solution. 
Result so far: 1918.0
If we take 7920 away from 8202, we end up with 282.
Take the next digit (5) from the dividend and append it to 282, then repeat: 2825 / 990

On to step 8:
990 can be fit into 2825 2 times, resulting in a remainder of 845.
Use 2 as the next digit of our solution. 
Result so far: 19182.0
If we subtract 1980 from 2825, we get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Advancing to step 9:
990 can be fit into 8450 8 times, resulting in a remainder of 530.
Record the quotient 8 as the next digit in the result. 
Result so far: 19182.8
If we take 7920 away from 8450, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 10:
5300 divided by 990 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 19182.85
If we subtract 4950 from 5300, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
The number 990 fits into 3500 3 times, leaving a remainder of 530.
Write down 3 as next digit of the result. 
Result so far: 19182.853
If we subtract 2970 from 3500, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 12:
990 goes into 5300 5 times with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 19182.8535
Subtract 4950 from 5300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
990 goes into 3500 3 times with a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 19182.85353
If we take 2970 away from 3500, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 14:
990 can be fit into 5300 5 times, resulting in a remainder of 350.
The next digit of our result is 5. 
Result so far: 19182.853535
The remainder is 350 after subtracting 4950 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 15:
The number 990 fits into 3500 3 times, leaving a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 19182.8535353
Subtracting 2970 from 3500 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 16:
990 goes into 5300 5 times with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 19182.85353535
If we take 4950 away from 5300, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final result is 19182.85353535 with a remainder of 3.5e-07.
