We look at the division of 354252 by 51 
The aim is to understand the frequency of 51 in 354252.

Step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 51

Going ahead to step 2:
51 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 51

Advancing to step 3:
If we divide 354 by 51, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 306 away from 354, we end up with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 51

Going ahead to step 4:
482 divided by 51 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtract 459 from 482 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 51

Going ahead to step 5:
The number 51 fits into 235 4 times, leaving a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 694.0
Subtract 204 from 235 to get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 51

Moving on to step 6:
If we divide 312 by 51, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6946.0
Subtracting 306 from 312 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.

On to step 7:
If we divide 60 by 51, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 6946.1
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 6946.11
The remainder is 39 after subtracting 51 from 90.
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 6946.11 with a balance of 0.039.
