Let's divide 71101399 by 990
We want to figure out the number of times 71101399 can be divided by 990.

Moving on to step 1:
7 divided by 990 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 990

Going ahead to step 2:
71 divided by 990 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 990

Step 3:
The number 990 fits into 711 0 times, leaving a remainder of 711.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 711 after subtracting 0 from 711.
Include the next digit (0) from the dividend after 711, then repeat: 7110 / 990

Going ahead to step 4:
990 can be fit into 7110 7 times, resulting in a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6930 from 7110 leaves us with 180.
Include the next digit (1) from the dividend after 180, then repeat: 1801 / 990

Step 5:
1801 divided by 990 is 1 with a remainder of 811.
The next digit of our result is 1. 
Result so far: 71.0
Subtracting 990 from 1801 leaves us with 811.
Fetch the next digit (3) from the dividend, attach it to 811 and continue: 8113 / 990

Moving on to step 6:
990 goes into 8113 8 times with a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
Subtract 7920 from 8113 to get 193.
Grab the next digit (9) from the dividend, add it to 193, then carry on: 1939 / 990

On to step 7:
1939 divided by 990 is 1 with a remainder of 949.
Write down 1 as next digit of the result. 
Result so far: 7181.0
If we subtract 990 from 1939, we get 949.
Take the next digit (9) from the dividend and append it to 949, then repeat: 9499 / 990

Going ahead to step 8:
When dividing 9499 by 990, we get 9 with a remainder of 589.
The number 9 becomes the next digit in our result. 
Result so far: 71819.0
Deduct 8910 from 9499 and we're left with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Going ahead to step 9:
If we divide 5890 by 990, we get 5 and a remainder of 940.
Use 5 as the next digit of our solution. 
Result so far: 71819.5
Deduct 4950 from 5890 and we're left with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Step 10:
When dividing 9400 by 990, we get 9 with a remainder of 490.
The next digit of our result is 9. 
Result so far: 71819.59
If we take 8910 away from 9400, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 11:
If we divide 4900 by 990, we get 4 and a remainder of 940.
Record the quotient 4 as the next digit in the result. 
Result so far: 71819.594
Subtract 3960 from 4900 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

On to step 12:
If we divide 9400 by 990, we get 9 and a remainder of 490.
The number 9 becomes the next digit in our result. 
Result so far: 71819.5949
Deduct 8910 from 9400 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 13:
990 can be fit into 4900 4 times, resulting in a remainder of 940.
Put 4 as the next digit of the answer. 
Result so far: 71819.59494
Subtract 3960 from 4900 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 14:
If we divide 9400 by 990, we get 9 and a remainder of 490.
Use 9 as the next digit of our solution. 
Result so far: 71819.594949
Subtract 8910 from 9400 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
990 goes into 4900 4 times with a remainder of 940.
The next digit of our result is 4. 
Result so far: 71819.5949494
If we subtract 3960 from 4900, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Going ahead to step 16:
990 can be fit into 9400 9 times, resulting in a remainder of 490.
Use 9 as the next digit of our solution. 
Result so far: 71819.59494949
The remainder is 490 after subtracting 8910 from 9400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final outcome is 71819.59494949, with a leftover of 4.9e-07.
