912764 ÷ 51 
The aim is to understand the frequency of 51 in 912764.

Advancing to step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 51

Advancing to step 2:
91 divided by 51 is 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 91, we get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 51

On to step 3:
51 goes into 402 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 357 from 402 to get 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 51

Moving on to step 4:
457 divided by 51 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 178.0
Subtract 408 from 457 to get 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 51

Going ahead to step 5:
The number 51 fits into 496 9 times, leaving a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 1789.0
Subtracting 459 from 496 leaves us with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 51

Advancing to step 6:
If we divide 374 by 51, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 17897.0
If we take 357 away from 374, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 17897.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
170 divided by 51 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 17897.33
Deduct 153 from 170 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 17897.33 and a remainder of 0.017.
