We divide 84297897 by 990
The aim is to understand the frequency of 990 in 84297897.

Step 1:
990 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 990

Going ahead to step 2:
When dividing 84 by 990, we get 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 990

Step 3:
The number 990 fits into 842 0 times, leaving a remainder of 842.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 842 and we're left with 842.
Append the next digit (9) from the dividend to 842 and continue with: 8429 / 990

On to step 4:
8429 divided by 990 is 8 with a remainder of 509.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 509 after subtracting 7920 from 8429.
Bring next digit (7) of the dividend behind the 509 and repeat the process: 5097 / 990

Let's proceed to step 5:
5097 divided by 990 is 5 with a remainder of 147.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 4950 from 5097 leaves us with 147.
Fetch the next digit (8) from the dividend, attach it to 147 and continue: 1478 / 990

Going ahead to step 6:
1478 divided by 990 is 1 with a remainder of 488.
Use 1 as the next digit of our solution. 
Result so far: 851.0
If we take 990 away from 1478, we end up with 488.
Grab the next digit (9) from the dividend, add it to 488, then carry on: 4889 / 990

Moving on to step 7:
4889 divided by 990 is 4 with a remainder of 929.
Put 4 as the next digit of the answer. 
Result so far: 8514.0
Subtract 3960 from 4889 to get 929.
Take the next digit (7) from the dividend and append it to 929, then repeat: 9297 / 990

Moving on to step 8:
The number 990 fits into 9297 9 times, leaving a remainder of 387.
Use 9 as the next digit of our solution. 
Result so far: 85149.0
Subtract 8910 from 9297 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 9:
The number 990 fits into 3870 3 times, leaving a remainder of 900.
The next digit of our result is 3. 
Result so far: 85149.3
If we take 2970 away from 3870, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Going ahead to step 10:
9000 divided by 990 is 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 85149.39
The remainder is 90 after subtracting 8910 from 9000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
990 can be fit into 900 0 times, resulting in a remainder of 900.
Use 0 as the next digit of our solution. 
Result so far: 85149.39
If we subtract 0 from 900, we get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 12:
990 can be fit into 9000 9 times, resulting in a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 85149.3909
If we take 8910 away from 9000, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
When dividing 900 by 990, we get 0 with a remainder of 900.
Use 0 as the next digit of our solution. 
Result so far: 85149.3909
Subtract 0 from 900 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

On to step 14:
990 goes into 9000 9 times with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 85149.390909
If we take 8910 away from 9000, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
When dividing 900 by 990, we get 0 with a remainder of 900.
The next digit of our result is 0. 
Result so far: 85149.390909
Deduct 0 from 900 and we're left with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

On to step 16:
When dividing 9000 by 990, we get 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 85149.39090909
If we take 8910 away from 9000, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 85149.39090909 with a balance of 9e-08.
