437739 divided by 51 
The aim is to understand the frequency of 51 in 437739.

Advancing to step 1:
4 divided by 51 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 51

Going ahead to step 2:
When dividing 43 by 51, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 51

Advancing to step 3:
437 divided by 51 is 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 408 from 437, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 51

Step 4:
The number 51 fits into 297 5 times, leaving a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 42 after subtracting 255 from 297.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 51

On to step 5:
The number 51 fits into 423 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 858.0
Subtracting 408 from 423 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 51

Let's proceed to step 6:
51 can be fit into 159 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 8583.0
The remainder is 6 after subtracting 153 from 159.
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:
51 goes into 60 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8583.1
If we subtract 51 from 60, we 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.

Going ahead to step 8:
If we divide 90 by 51, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 8583.11
Subtracting 51 from 90 leaves us 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 8583.11 with a balance of 0.039.
