We look at the division of 807542 by 98 
The aim is to understand the frequency of 98 in 807542.

Advancing to step 1:
When dividing 8 by 98, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 98

Step 2:
The number 98 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 98

Advancing to step 3:
If we divide 807 by 98, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 784 away from 807, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 98

On to step 4:
235 divided by 98 is 2 with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 39 after subtracting 196 from 235.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 98

Going ahead to step 5:
98 goes into 394 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 824.0
If we subtract 392 from 394, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 98

Advancing to step 6:
When dividing 22 by 98, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 8240.0
Subtract 0 from 22 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
98 goes into 220 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8240.2
Deduct 196 from 220 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
98 can be fit into 240 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 8240.22
If we take 196 away from 240, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8240.22 with a remainder of 0.044.
