Let's divide 657604 by 98
The aim is to understand the frequency of 98 in 657604.

Going ahead to step 1:
If we divide 6 by 98, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 98

On to step 2:
65 divided by 98 is 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 98

Moving on to step 3:
If we divide 657 by 98, we get 6 and a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 588 from 657 and we're left with 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 98

Step 4:
If we divide 696 by 98, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtracting 686 from 696 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 98

On to step 5:
98 can be fit into 100 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 671.0
Deduct 98 from 100 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 98

Moving on to step 6:
The number 98 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 6710.0
If we subtract 0 from 24, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
The number 98 fits into 240 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6710.2
Subtract 196 from 240 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
If we divide 440 by 98, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 6710.24
Deduct 392 from 440 and we're left 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 9:
If we divide 480 by 98, we get 4 and a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 6710.244
Subtracting 392 from 480 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 6710.244, and the remainder is 0.0088.
