We're dividing 650640 by 98 
The aim is to understand the frequency of 98 in 650640.

Moving on to step 1:
The number 98 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 98

Moving on to step 2:
98 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 98

Let's proceed to step 3:
98 goes into 650 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 588 from 650, we get 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 98

Step 4:
The number 98 fits into 626 6 times, leaving a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 588 from 626 and we're left with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 98

Advancing to step 5:
98 can be fit into 384 3 times, resulting in a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 663.0
Deduct 294 from 384 and we're left with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 98

Going ahead to step 6:
900 divided by 98 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6639.0
The remainder is 18 after subtracting 882 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 98, we get 1 and a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 6639.1
If we take 98 away from 180, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
98 can be fit into 820 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 6639.18
Subtracting 784 from 820 leaves us 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.

Advancing to step 9:
98 can be fit into 360 3 times, resulting in a remainder of 66.
The next digit of our result is 3. 
Result so far: 6639.183
Subtract 294 from 360 to 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.

Moving on to step 10:
660 divided by 98 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 6639.1836
If we subtract 588 from 660, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
When dividing 720 by 98, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 6639.18367
Deduct 686 from 720 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
98 can be fit into 340 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 6639.183673
If we subtract 294 from 340, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
98 can be fit into 460 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 6639.1836734
Deduct 392 from 460 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
When dividing 680 by 98, we get 6 with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 6639.18367346
Subtracting 588 from 680 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 6639.18367346 with a remainder of 9.2e-08.
