We look at the division of 70766864 by 990 
The aim is to understand the frequency of 990 in 70766864.

Going ahead to step 1:
990 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 990

Step 2:
If we divide 70 by 990, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 990

Moving on to step 3:
990 goes into 707 0 times with a remainder of 707.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 707 and we're left with 707.
Include the next digit (6) from the dividend after 707, then repeat: 7076 / 990

On to step 4:
When dividing 7076 by 990, we get 7 with a remainder of 146.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6930 from 7076 leaves us with 146.
Take the next digit (6) from the dividend and append it to 146, then repeat: 1466 / 990

On to step 5:
990 goes into 1466 1 times with a remainder of 476.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Deduct 990 from 1466 and we're left with 476.
Grab the next digit (8) from the dividend, add it to 476, then carry on: 4768 / 990

Step 6:
990 goes into 4768 4 times with a remainder of 808.
The next digit of our result is 4. 
Result so far: 714.0
If we take 3960 away from 4768, we end up with 808.
Fetch the next digit (6) from the dividend, attach it to 808 and continue: 8086 / 990

Step 7:
If we divide 8086 by 990, we get 8 and a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 7148.0
If we take 7920 away from 8086, we end up with 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 990

Moving on to step 8:
1664 divided by 990 is 1 with a remainder of 674.
Record the quotient 1 as the next digit in the result. 
Result so far: 71481.0
If we take 990 away from 1664, we end up with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 9:
990 can be fit into 6740 6 times, resulting in a remainder of 800.
The next digit of our result is 6. 
Result so far: 71481.6
If we take 5940 away from 6740, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 10:
The number 990 fits into 8000 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 71481.68
Deduct 7920 from 8000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
990 can be fit into 800 0 times, resulting in a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 71481.68
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 12:
8000 divided by 990 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 71481.6808
If we subtract 7920 from 8000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
990 can be fit into 800 0 times, resulting in a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 71481.6808
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 14:
When dividing 8000 by 990, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 71481.680808
If we take 7920 away from 8000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
990 goes into 800 0 times with a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 71481.680808
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 16:
If we divide 8000 by 990, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 71481.68080808
If we subtract 7920 from 8000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 71481.68080808 with a remainder of 8e-08.
