138931 ÷ 98 
The aim is to understand the frequency of 98 in 138931.

Moving on to step 1:
If we divide 1 by 98, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 98

Let's proceed to step 2:
When dividing 13 by 98, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 98

Moving on to step 3:
If we divide 138 by 98, we get 1 and a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 40 after subtracting 98 from 138.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 98

Advancing to step 4:
98 goes into 409 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 392 from 409 to get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 98

Advancing to step 5:
98 can be fit into 173 1 times, resulting in a remainder of 75.
The next digit of our result is 1. 
Result so far: 141.0
Deduct 98 from 173 and we're left with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 98

On to step 6:
751 divided by 98 is 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 1417.0
Subtracting 686 from 751 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
The number 98 fits into 650 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 1417.6
The remainder is 62 after subtracting 588 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 98, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1417.66
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 1417.66, and the remainder is 0.032.
