We look at the division of 821015 by 98 
The aim is to understand the frequency of 98 in 821015.

Advancing to step 1:
If we divide 8 by 98, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 98

Moving on to step 2:
When dividing 82 by 98, we get 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 98

Moving on to step 3:
The number 98 fits into 821 8 times, leaving a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 784 from 821 and we're left with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 98

Let's proceed to step 4:
If we divide 370 by 98, we get 3 and a remainder of 76.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 294 from 370 leaves us with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 98

Let's proceed to step 5:
If we divide 761 by 98, we get 7 and a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 837.0
Deduct 686 from 761 and we're left with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 98

Let's proceed to step 6:
The number 98 fits into 755 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 8377.0
Subtracting 686 from 755 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
When dividing 690 by 98, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 8377.7
If we subtract 686 from 690, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
98 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8377.7
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
98 goes into 400 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 8377.704
Deduct 392 from 400 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 98 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 8377.704
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
800 divided by 98 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8377.70408
If we take 784 away from 800, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
160 divided by 98 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 8377.704081
Subtracting 98 from 160 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
If we divide 620 by 98, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 8377.7040816
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.

Step 14:
98 can be fit into 320 3 times, resulting in a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 8377.70408163
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 8377.70408163 and a remainder of 2.6e-08.
