We're dividing 77392846 by 990 
Let's see how many times 990 fits into 77392846.

Advancing to step 1:
If we divide 7 by 990, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 990

Going ahead to step 2:
If we divide 77 by 990, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 990

Going ahead to step 3:
990 can be fit into 773 0 times, resulting in a remainder of 773.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 773 and we're left with 773.
Include the next digit (9) from the dividend after 773, then repeat: 7739 / 990

Step 4:
7739 divided by 990 is 7 with a remainder of 809.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 6930 from 7739 to get 809.
Fetch the next digit (2) from the dividend, attach it to 809 and continue: 8092 / 990

Let's proceed to step 5:
8092 divided by 990 is 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 7920 from 8092 and we're left with 172.
Bring next digit (8) of the dividend behind the 172 and repeat the process: 1728 / 990

Moving on to step 6:
The number 990 fits into 1728 1 times, leaving a remainder of 738.
The next digit of our result is 1. 
Result so far: 781.0
If we take 990 away from 1728, we end up with 738.
Bring next digit (4) of the dividend behind the 738 and repeat the process: 7384 / 990

Advancing to step 7:
990 goes into 7384 7 times with a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 7817.0
Subtracting 6930 from 7384 leaves us with 454.
Bring next digit (6) of the dividend behind the 454 and repeat the process: 4546 / 990

Going ahead to step 8:
990 can be fit into 4546 4 times, resulting in a remainder of 586.
Write down 4 as next digit of the result. 
Result so far: 78174.0
Subtracting 3960 from 4546 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 9:
If we divide 5860 by 990, we get 5 and a remainder of 910.
The number 5 becomes the next digit in our result. 
Result so far: 78174.5
Subtracting 4950 from 5860 leaves us with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Let's proceed to step 10:
9100 divided by 990 is 9 with a remainder of 190.
Write down 9 as next digit of the result. 
Result so far: 78174.59
If we subtract 8910 from 9100, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
1900 divided by 990 is 1 with a remainder of 910.
The number 1 becomes the next digit in our result. 
Result so far: 78174.591
Subtract 990 from 1900 to get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Moving on to step 12:
The number 990 fits into 9100 9 times, leaving a remainder of 190.
The next digit of our result is 9. 
Result so far: 78174.5919
Subtracting 8910 from 9100 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 13:
If we divide 1900 by 990, we get 1 and a remainder of 910.
Use 1 as the next digit of our solution. 
Result so far: 78174.59191
Deduct 990 from 1900 and we're left with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Let's proceed to step 14:
If we divide 9100 by 990, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 78174.591919
Subtracting 8910 from 9100 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 15:
1900 divided by 990 is 1 with a remainder of 910.
The number 1 becomes the next digit in our result. 
Result so far: 78174.5919191
If we subtract 990 from 1900, we get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

On to step 16:
990 can be fit into 9100 9 times, resulting in a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 78174.59191919
Deduct 8910 from 9100 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 78174.59191919 and a remainder of 1.9e-07.
