We divide 763926 by 51
The aim is to understand the frequency of 51 in 763926.

Advancing to step 1:
If we divide 7 by 51, we get 0 and 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 (6) from the dividend and append it to 7, then repeat: 76 / 51

Let's proceed to step 2:
76 divided by 51 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 76, we get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 51

On to step 3:
51 goes into 253 4 times with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 204 from 253 leaves us with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 51

Let's proceed to step 4:
51 goes into 499 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 459 from 499 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 51

Let's proceed to step 5:
When dividing 402 by 51, we get 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 1497.0
If we subtract 357 from 402, we get 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 51

On to step 6:
456 divided by 51 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 14978.0
Subtracting 408 from 456 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
51 goes into 480 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 14978.9
Deduct 459 from 480 and we're left 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.

Going ahead to step 8:
If we divide 210 by 51, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14978.94
If we subtract 204 from 210, we 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.

Step 9:
If we divide 60 by 51, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 14978.941
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.

Going ahead to step 10:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 14978.9411
Deduct 51 from 90 and we're left 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.

After the division, we end up with 14978.9411 and a remainder of 0.00039.
