8790 divided by 98 
The aim is to understand the frequency of 98 in 8790.

Step 1:
When dividing 8 by 98, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 98

Going ahead to step 2:
98 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 98

Going ahead to step 3:
98 can be fit into 879 8 times, resulting in a remainder of 95.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 784 from 879, we get 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 98

Advancing to step 4:
The number 98 fits into 950 9 times, leaving a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 882 from 950 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 5:
98 can be fit into 680 6 times, resulting in a remainder of 92.
The next digit of our result is 6. 
Result so far: 89.6
The remainder is 92 after subtracting 588 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 6:
98 can be fit into 920 9 times, resulting in a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 89.69
The remainder is 38 after subtracting 882 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
98 goes into 380 3 times with a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 89.693
Subtract 294 from 380 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 8:
If we divide 860 by 98, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 89.6938
The remainder is 76 after subtracting 784 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
If we divide 760 by 98, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 89.69387
If we subtract 686 from 760, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
98 can be fit into 740 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 89.693877
If we take 686 away from 740, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 89.693877 with a balance of 5.4e-06.
