Let's divide 72731913 by 51
The aim is to understand the frequency of 51 in 72731913.

Let's proceed to step 1:
7 divided by 51 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 51

Advancing to step 2:
72 divided by 51 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 72, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 51

On to step 3:
The number 51 fits into 217 4 times, leaving a remainder of 13.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 204 from 217 to get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 51

On to step 4:
51 can be fit into 133 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 142.0
If we subtract 102 from 133, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 51

Let's proceed to step 5:
When dividing 311 by 51, we get 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
Subtract 306 from 311 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 51

On to step 6:
The number 51 fits into 59 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 14261.0
Subtract 51 from 59 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 51

Advancing to step 7:
When dividing 81 by 51, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 142611.0
Subtracting 51 from 81 leaves us with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 51

On to step 8:
When dividing 303 by 51, we get 5 with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 1426115.0
If we subtract 255 from 303, we 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.

On to step 9:
51 goes into 480 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1426115.9
If we take 459 away from 480, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
When dividing 210 by 51, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1426115.94
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1426115.941
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.

Let's proceed to step 12:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1426115.9411
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.

The final result is 1426115.9411 with a remainder of 0.00039.
