Let's divide 15391951 by 98
The aim is to understand the frequency of 98 in 15391951.

On to step 1:
The number 98 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 98

Let's proceed to step 2:
15 divided by 98 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 98

On to step 3:
98 goes into 153 1 times with a remainder of 55.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 98 from 153 leaves us with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 98

Let's proceed to step 4:
98 goes into 559 5 times with a remainder of 69.
The next digit of our result is 5. 
Result so far: 15.0
If we take 490 away from 559, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 98

Advancing to step 5:
98 can be fit into 691 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we subtract 686 from 691, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 98

Moving on to step 6:
When dividing 59 by 98, we get 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 1570.0
If we take 0 away from 59, we end up with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 98

Advancing to step 7:
The number 98 fits into 595 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 15706.0
The remainder is 7 after subtracting 588 from 595.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 98

Let's proceed to step 8:
The number 98 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 157060.0
Subtracting 0 from 71 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
If we divide 710 by 98, we get 7 and a remainder of 24.
The next digit of our result is 7. 
Result so far: 157060.7
If we subtract 686 from 710, 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.

Let's proceed to step 10:
The number 98 fits into 240 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 157060.72
The remainder is 44 after subtracting 196 from 240.
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 11:
When dividing 440 by 98, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 157060.724
Subtract 392 from 440 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
480 divided by 98 is 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 157060.7244
Deduct 392 from 480 and we're left 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.

After the division, we end up with 157060.7244 and a remainder of 0.00088.
