We're dividing 641851 by 98 
The aim is to understand the frequency of 98 in 641851.

Advancing to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 98

Let's proceed to step 2:
The number 98 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 98

On to step 3:
98 can be fit into 641 6 times, resulting in a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 588 from 641 and we're left with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 98

Moving on to step 4:
538 divided by 98 is 5 with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 490 from 538 and we're left with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 98

Going ahead to step 5:
98 goes into 485 4 times with a remainder of 93.
Write down 4 as next digit of the result. 
Result so far: 654.0
If we subtract 392 from 485, we get 93.
Take the next digit (1) from the dividend and append it to 93, then repeat: 931 / 98

Step 6:
931 divided by 98 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 6549.0
The remainder is 49 after subtracting 882 from 931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 98 fits into 490 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6549.5
Deduct 490 from 490 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
98 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6549.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 98, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6549.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6549.5, with a leftover of 0.0.
