Let's divide 77770895 by 990
We want to figure out the number of times 77770895 can be divided by 990.

Moving on to step 1:
The number 990 fits into 7 0 times, leaving 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.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 990

Advancing to step 2:
The number 990 fits into 77 0 times, leaving 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.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 990

Step 3:
990 goes into 777 0 times with a remainder of 777.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 777 after subtracting 0 from 777.
Grab the next digit (7) from the dividend, add it to 777, then carry on: 7777 / 990

Let's proceed to step 4:
990 goes into 7777 7 times with a remainder of 847.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6930 from 7777 leaves us with 847.
Bring next digit (0) of the dividend behind the 847 and repeat the process: 8470 / 990

Moving on to step 5:
990 can be fit into 8470 8 times, resulting in a remainder of 550.
The next digit of our result is 8. 
Result so far: 78.0
If we take 7920 away from 8470, we end up with 550.
Fetch the next digit (8) from the dividend, attach it to 550 and continue: 5508 / 990

Going ahead to step 6:
The number 990 fits into 5508 5 times, leaving a remainder of 558.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
The remainder is 558 after subtracting 4950 from 5508.
Take the next digit (9) from the dividend and append it to 558, then repeat: 5589 / 990

Step 7:
990 goes into 5589 5 times with a remainder of 639.
Record the quotient 5 as the next digit in the result. 
Result so far: 7855.0
If we take 4950 away from 5589, we end up with 639.
Include the next digit (5) from the dividend after 639, then repeat: 6395 / 990

Let's proceed to step 8:
The number 990 fits into 6395 6 times, leaving a remainder of 455.
Use 6 as the next digit of our solution. 
Result so far: 78556.0
If we subtract 5940 from 6395, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 9:
990 can be fit into 4550 4 times, resulting in a remainder of 590.
The number 4 becomes the next digit in our result. 
Result so far: 78556.4
The remainder is 590 after subtracting 3960 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 10:
When dividing 5900 by 990, we get 5 with a remainder of 950.
Write down 5 as next digit of the result. 
Result so far: 78556.45
Subtracting 4950 from 5900 leaves us with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Advancing to step 11:
If we divide 9500 by 990, we get 9 and a remainder of 590.
The next digit of our result is 9. 
Result so far: 78556.459
Subtract 8910 from 9500 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
990 can be fit into 5900 5 times, resulting in a remainder of 950.
The number 5 becomes the next digit in our result. 
Result so far: 78556.4595
The remainder is 950 after subtracting 4950 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Going ahead to step 13:
990 can be fit into 9500 9 times, resulting in a remainder of 590.
Write down 9 as next digit of the result. 
Result so far: 78556.45959
Subtract 8910 from 9500 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 14:
If we divide 5900 by 990, we get 5 and a remainder of 950.
Record the quotient 5 as the next digit in the result. 
Result so far: 78556.459595
Subtracting 4950 from 5900 leaves us with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

On to step 15:
990 goes into 9500 9 times with a remainder of 590.
Put 9 as the next digit of the answer. 
Result so far: 78556.4595959
Deduct 8910 from 9500 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 16:
When dividing 5900 by 990, we get 5 with a remainder of 950.
The number 5 becomes the next digit in our result. 
Result so far: 78556.45959595
Deduct 4950 from 5900 and we're left with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

The final outcome is 78556.45959595, with a leftover of 9.5e-07.
