We're dividing 98645175 by 51 
The aim is to understand the frequency of 51 in 98645175.

Going ahead to step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 51

Moving on to step 2:
If we divide 98 by 51, we get 1 and a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 47 after subtracting 51 from 98.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 51

Let's proceed to step 3:
51 can be fit into 476 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 459 from 476 to get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 51

Step 4:
51 goes into 174 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
The remainder is 21 after subtracting 153 from 174.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 51

Let's proceed to step 5:
215 divided by 51 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 1934.0
Subtracting 204 from 215 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 51

Advancing to step 6:
51 can be fit into 111 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 19342.0
Subtract 102 from 111 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 51

Going ahead to step 7:
The number 51 fits into 97 1 times, leaving a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 193421.0
If we subtract 51 from 97, we get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 51

Step 8:
51 goes into 465 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1934219.0
Subtracting 459 from 465 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
51 can be fit into 60 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1934219.1
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1934219.11
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 1934219.11 with a balance of 0.039.
