85764834 ÷ 990 
The aim is to understand the frequency of 990 in 85764834.

Going ahead to step 1:
8 divided by 990 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 990

Going ahead to step 2:
990 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 990

Moving on to step 3:
857 divided by 990 is 0 with a remainder of 857.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 857 to get 857.
Append the next digit (6) from the dividend to 857 and continue with: 8576 / 990

On to step 4:
If we divide 8576 by 990, we get 8 and a remainder of 656.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7920 from 8576 leaves us with 656.
Bring next digit (4) of the dividend behind the 656 and repeat the process: 6564 / 990

Advancing to step 5:
990 can be fit into 6564 6 times, resulting in a remainder of 624.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 5940 from 6564, we get 624.
Include the next digit (8) from the dividend after 624, then repeat: 6248 / 990

Step 6:
990 goes into 6248 6 times with a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
Deduct 5940 from 6248 and we're left with 308.
Append the next digit (3) from the dividend to 308 and continue with: 3083 / 990

Moving on to step 7:
The number 990 fits into 3083 3 times, leaving a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 8663.0
Subtract 2970 from 3083 to get 113.
Append the next digit (4) from the dividend to 113 and continue with: 1134 / 990

Moving on to step 8:
The number 990 fits into 1134 1 times, leaving a remainder of 144.
The next digit of our result is 1. 
Result so far: 86631.0
Subtracting 990 from 1134 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
If we divide 1440 by 990, we get 1 and a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 86631.1
Subtract 990 from 1440 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
990 goes into 4500 4 times with a remainder of 540.
Write down 4 as next digit of the result. 
Result so far: 86631.14
If we subtract 3960 from 4500, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
When dividing 5400 by 990, we get 5 with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 86631.145
Subtracting 4950 from 5400 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 12:
The number 990 fits into 4500 4 times, leaving a remainder of 540.
Put 4 as the next digit of the answer. 
Result so far: 86631.1454
If we subtract 3960 from 4500, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 13:
5400 divided by 990 is 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 86631.14545
Deduct 4950 from 5400 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
If we divide 4500 by 990, we get 4 and a remainder of 540.
The next digit of our result is 4. 
Result so far: 86631.145454
If we take 3960 away from 4500, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 15:
When dividing 5400 by 990, we get 5 with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 86631.1454545
Subtracting 4950 from 5400 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
990 goes into 4500 4 times with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 86631.14545454
If we subtract 3960 from 4500, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 86631.14545454 and a remainder of 5.4e-07.
