80235745 divided by 990 
Our goal is to divide 80235745 by 990.

Step 1:
When dividing 8 by 990, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 990

Step 2:
990 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 990

Step 3:
990 goes into 802 0 times with a remainder of 802.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 802 and we're left with 802.
Bring next digit (3) of the dividend behind the 802 and repeat the process: 8023 / 990

Going ahead to step 4:
When dividing 8023 by 990, we get 8 with a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7920 from 8023 and we're left with 103.
Fetch the next digit (5) from the dividend, attach it to 103 and continue: 1035 / 990

Going ahead to step 5:
990 can be fit into 1035 1 times, resulting in a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtracting 990 from 1035 leaves us with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 990

Advancing to step 6:
The number 990 fits into 457 0 times, leaving a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 810.0
If we take 0 away from 457, we end up with 457.
Take the next digit (4) from the dividend and append it to 457, then repeat: 4574 / 990

Let's proceed to step 7:
When dividing 4574 by 990, we get 4 with a remainder of 614.
Put 4 as the next digit of the answer. 
Result so far: 8104.0
Deduct 3960 from 4574 and we're left with 614.
Append the next digit (5) from the dividend to 614 and continue with: 6145 / 990

Going ahead to step 8:
If we divide 6145 by 990, we get 6 and a remainder of 205.
The next digit of our result is 6. 
Result so far: 81046.0
If we take 5940 away from 6145, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
990 goes into 2050 2 times with a remainder of 70.
The next digit of our result is 2. 
Result so far: 81046.2
Subtracting 1980 from 2050 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
990 goes into 700 0 times with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 81046.2
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 11:
990 goes into 7000 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 81046.207
Subtract 6930 from 7000 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
990 goes into 700 0 times with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 81046.207
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
990 can be fit into 7000 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 81046.20707
If we subtract 6930 from 7000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
The number 990 fits into 700 0 times, leaving a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 81046.20707
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 15:
When dividing 7000 by 990, we get 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 81046.2070707
Subtract 6930 from 7000 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
700 divided by 990 is 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 81046.2070707
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 81046.2070707 with a remaining 7e-07.
