7702750 ÷ 990 
The aim is to understand the frequency of 990 in 7702750.

Going ahead to step 1:
990 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
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

On to step 2:
990 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 990

Advancing to step 3:
If we divide 770 by 990, we get 0 and a remainder of 770.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 770 and we're left with 770.
Bring next digit (2) of the dividend behind the 770 and repeat the process: 7702 / 990

Moving on to step 4:
When dividing 7702 by 990, we get 7 with a remainder of 772.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 6930 from 7702, we get 772.
Fetch the next digit (7) from the dividend, attach it to 772 and continue: 7727 / 990

Advancing to step 5:
990 can be fit into 7727 7 times, resulting in a remainder of 797.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we take 6930 away from 7727, we end up with 797.
Fetch the next digit (5) from the dividend, attach it to 797 and continue: 7975 / 990

Advancing to step 6:
The number 990 fits into 7975 8 times, leaving a remainder of 55.
The next digit of our result is 8. 
Result so far: 778.0
Deduct 7920 from 7975 and we're left with 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 990

Going ahead to step 7:
990 goes into 550 0 times with a remainder of 550.
The next digit of our result is 0. 
Result so far: 7780.0
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 8:
The number 990 fits into 5500 5 times, leaving a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 7780.5
Subtracting 4950 from 5500 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 9:
990 goes into 5500 5 times with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 7780.55
If we subtract 4950 from 5500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The quotient of the division is 7780.55, and the remainder is 0.55.
