76392175 ÷ 51 
The aim is to understand the frequency of 51 in 76392175.

Let's proceed to step 1:
51 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 51

Advancing to step 2:
The number 51 fits into 76 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 76, we end up with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 51

Moving on to step 3:
51 goes into 253 4 times with a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 204 from 253, we get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 51

On to step 4:
499 divided by 51 is 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
If we subtract 459 from 499, we get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 51

Let's proceed to step 5:
402 divided by 51 is 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
The remainder is 45 after subtracting 357 from 402.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 51

Going ahead to step 6:
If we divide 451 by 51, we get 8 and a remainder of 43.
The number 8 becomes the next digit in our result. 
Result so far: 14978.0
The remainder is 43 after subtracting 408 from 451.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 51

Moving on to step 7:
If we divide 437 by 51, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 149788.0
If we subtract 408 from 437, we get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 51

Advancing to step 8:
If we divide 295 by 51, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1497885.0
If we subtract 255 from 295, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497885.7
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1497885.78
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
When dividing 220 by 51, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1497885.784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
If we divide 160 by 51, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1497885.7843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
51 goes into 70 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1497885.78431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1497885.784313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 15:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1497885.7843137
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 16:
When dividing 130 by 51, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1497885.78431372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 1497885.78431372, with a leftover of 2.8e-08.
