We're dividing 18171649 by 990 
We want to divide 18171649 by 990.

Going ahead to step 1:
The number 990 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 990

Moving on to step 2:
When dividing 18 by 990, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 990

On to step 3:
990 goes into 181 0 times with a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 181, we get 181.
Include the next digit (7) from the dividend after 181, then repeat: 1817 / 990

Advancing to step 4:
1817 divided by 990 is 1 with a remainder of 827.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 990 away from 1817, we end up with 827.
Append the next digit (1) from the dividend to 827 and continue with: 8271 / 990

Going ahead to step 5:
990 can be fit into 8271 8 times, resulting in a remainder of 351.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 351 after subtracting 7920 from 8271.
Bring next digit (6) of the dividend behind the 351 and repeat the process: 3516 / 990

Going ahead to step 6:
If we divide 3516 by 990, we get 3 and a remainder of 546.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Deduct 2970 from 3516 and we're left with 546.
Fetch the next digit (4) from the dividend, attach it to 546 and continue: 5464 / 990

Moving on to step 7:
5464 divided by 990 is 5 with a remainder of 514.
Put 5 as the next digit of the answer. 
Result so far: 1835.0
Subtract 4950 from 5464 to get 514.
Take the next digit (9) from the dividend and append it to 514, then repeat: 5149 / 990

On to step 8:
5149 divided by 990 is 5 with a remainder of 199.
The number 5 becomes the next digit in our result. 
Result so far: 18355.0
Subtract 4950 from 5149 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
990 goes into 1990 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 18355.2
The remainder is 10 after subtracting 1980 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 990, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 18355.2
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
When dividing 1000 by 990, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 18355.201
If we subtract 990 from 1000, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 990, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 18355.201
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
990 goes into 1000 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 18355.20101
Subtracting 990 from 1000 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
990 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 18355.20101
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
990 can be fit into 1000 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 18355.2010101
If we subtract 990 from 1000, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 16:
The number 990 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 18355.2010101
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 18355.2010101, and the remainder is 1e-07.
