We're dividing 79465139 by 990 
Our goal is to divide 79465139 by 990.

Going ahead to step 1:
When dividing 7 by 990, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 990

Moving on to step 2:
If we divide 79 by 990, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 990

Let's proceed to step 3:
794 divided by 990 is 0 with a remainder of 794.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 794, we get 794.
Take the next digit (6) from the dividend and append it to 794, then repeat: 7946 / 990

Step 4:
When dividing 7946 by 990, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7920 from 7946, we get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 990

Step 5:
When dividing 265 by 990, we get 0 with a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 265, we get 265.
Grab the next digit (1) from the dividend, add it to 265, then carry on: 2651 / 990

Moving on to step 6:
2651 divided by 990 is 2 with a remainder of 671.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
If we take 1980 away from 2651, we end up with 671.
Grab the next digit (3) from the dividend, add it to 671, then carry on: 6713 / 990

Let's proceed to step 7:
990 goes into 6713 6 times with a remainder of 773.
Write down 6 as next digit of the result. 
Result so far: 8026.0
Subtracting 5940 from 6713 leaves us with 773.
Include the next digit (9) from the dividend after 773, then repeat: 7739 / 990

Advancing to step 8:
The number 990 fits into 7739 7 times, leaving a remainder of 809.
Put 7 as the next digit of the answer. 
Result so far: 80267.0
Deduct 6930 from 7739 and we're left with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Step 9:
8090 divided by 990 is 8 with a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 80267.8
Deduct 7920 from 8090 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
1700 divided by 990 is 1 with a remainder of 710.
Record the quotient 1 as the next digit in the result. 
Result so far: 80267.81
The remainder is 710 after subtracting 990 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 11:
If we divide 7100 by 990, we get 7 and a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 80267.817
If we take 6930 away from 7100, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
990 goes into 1700 1 times with a remainder of 710.
The number 1 becomes the next digit in our result. 
Result so far: 80267.8171
The remainder is 710 after subtracting 990 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 13:
990 goes into 7100 7 times with a remainder of 170.
The next digit of our result is 7. 
Result so far: 80267.81717
Subtracting 6930 from 7100 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 14:
When dividing 1700 by 990, we get 1 with a remainder of 710.
Record the quotient 1 as the next digit in the result. 
Result so far: 80267.817171
Subtracting 990 from 1700 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 15:
990 goes into 7100 7 times with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 80267.8171717
Subtracting 6930 from 7100 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 16:
The number 990 fits into 1700 1 times, leaving a remainder of 710.
Put 1 as the next digit of the answer. 
Result so far: 80267.81717171
Deduct 990 from 1700 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final result is 80267.81717171 with a remainder of 7.1e-07.
