We're dividing 152129 by 98 
The aim is to understand the frequency of 98 in 152129.

Going ahead to step 1:
98 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 98

Going ahead to step 2:
98 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 98

Advancing to step 3:
When dividing 152 by 98, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 54 after subtracting 98 from 152.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 98

Advancing to step 4:
98 goes into 541 5 times with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 490 from 541, we get 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 98

Going ahead to step 5:
When dividing 512 by 98, we get 5 with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we subtract 490 from 512, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 98

On to step 6:
98 goes into 229 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 1552.0
Deduct 196 from 229 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
If we divide 330 by 98, we get 3 and a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 1552.3
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
The number 98 fits into 360 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 1552.33
If we subtract 294 from 360, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 1552.33 with a remainder of 0.066.
