We're dividing 98101988 by 631 
The aim is to understand the frequency of 631 in 98101988.

Moving on to step 1:
The number 631 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 631

Let's proceed to step 2:
When dividing 98 by 631, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Append the next digit (1) from the dividend to 98 and continue with: 981 / 631

On to step 3:
631 can be fit into 981 1 times, resulting in a remainder of 350.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 631 away from 981, we end up with 350.
Append the next digit (0) from the dividend to 350 and continue with: 3500 / 631

Moving on to step 4:
631 can be fit into 3500 5 times, resulting in a remainder of 345.
The next digit of our result is 5. 
Result so far: 15.0
If we take 3155 away from 3500, we end up with 345.
Include the next digit (1) from the dividend after 345, then repeat: 3451 / 631

Moving on to step 5:
If we divide 3451 by 631, we get 5 and a remainder of 296.
The next digit of our result is 5. 
Result so far: 155.0
If we subtract 3155 from 3451, we get 296.
Include the next digit (9) from the dividend after 296, then repeat: 2969 / 631

On to step 6:
631 goes into 2969 4 times with a remainder of 445.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
Deduct 2524 from 2969 and we're left with 445.
Append the next digit (8) from the dividend to 445 and continue with: 4458 / 631

Moving on to step 7:
If we divide 4458 by 631, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 15547.0
Subtracting 4417 from 4458 leaves us with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 631

On to step 8:
The number 631 fits into 418 0 times, leaving a remainder of 418.
The number 0 becomes the next digit in our result. 
Result so far: 155470.0
Subtracting 0 from 418 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
If we divide 4180 by 631, we get 6 and a remainder of 394.
The number 6 becomes the next digit in our result. 
Result so far: 155470.6
Subtract 3786 from 4180 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
The number 631 fits into 3940 6 times, leaving a remainder of 154.
Use 6 as the next digit of our solution. 
Result so far: 155470.66
If we take 3786 away from 3940, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The quotient of the division is 155470.66, and the remainder is 0.154.
