We're dividing 635880 by 98 
The aim is to understand the frequency of 98 in 635880.

On to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 98

On to step 2:
The number 98 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 98

Step 3:
635 divided by 98 is 6 with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 588 from 635 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 98

Advancing to step 4:
98 can be fit into 478 4 times, resulting in a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 392 from 478 and we're left with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 98

Moving on to step 5:
The number 98 fits into 868 8 times, leaving a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Deduct 784 from 868 and we're left with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 98

On to step 6:
If we divide 840 by 98, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 6488.0
Subtracting 784 from 840 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
The number 98 fits into 560 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 6488.5
The remainder is 70 after subtracting 490 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
98 goes into 700 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 6488.57
The remainder is 14 after subtracting 686 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 98 fits into 140 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 6488.571
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
420 divided by 98 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 6488.5714
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
98 goes into 280 2 times with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 6488.57142
If we subtract 196 from 280, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
If we divide 840 by 98, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6488.571428
Subtracting 784 from 840 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
If we divide 560 by 98, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 6488.5714285
Subtracting 490 from 560 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
If we divide 700 by 98, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 6488.57142857
Deduct 686 from 700 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 6488.57142857 with a balance of 1.4e-08.
