639396 divided by 98 
The aim is to understand the frequency of 98 in 639396.

Moving on to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 98

On to step 2:
98 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 98

Let's proceed to step 3:
98 goes into 639 6 times with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 588 away from 639, we end up with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 98

Moving on to step 4:
If we divide 513 by 98, we get 5 and a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtract 490 from 513 to get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 98

Going ahead to step 5:
98 goes into 239 2 times with a remainder of 43.
The next digit of our result is 2. 
Result so far: 652.0
Subtracting 196 from 239 leaves us with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 98

Let's proceed to step 6:
The number 98 fits into 436 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 6524.0
Subtracting 392 from 436 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
98 can be fit into 440 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 6524.4
If we take 392 away from 440, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
When dividing 480 by 98, we get 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 6524.44
The remainder is 88 after subtracting 392 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 6524.44 with a balance of 0.088.
