We look at the division of 147611 by 51 
The aim is to understand the frequency of 51 in 147611.

Advancing to step 1:
The number 51 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
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 51

Advancing to step 2:
The number 51 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 51

Moving on to step 3:
When dividing 147 by 51, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
If we take 102 away from 147, we end up with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 51

Step 4:
51 goes into 456 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 408 from 456 to get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 51

Let's proceed to step 5:
51 goes into 481 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 459 away from 481, we end up with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 51

Advancing to step 6:
If we divide 221 by 51, we get 4 and a remainder of 17.
The next digit of our result is 4. 
Result so far: 2894.0
If we subtract 204 from 221, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2894.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2894.33
Subtracting 153 from 170 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 2894.33, with a leftover of 0.017.
