We're dividing 346692 by 51 
The aim is to understand the frequency of 51 in 346692.

Going ahead to step 1:
3 divided by 51 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 51

Let's proceed to step 2:
If we divide 34 by 51, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 51

Moving on to step 3:
51 can be fit into 346 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 306 from 346 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 51

Advancing to step 4:
The number 51 fits into 406 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 357 from 406 to get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 51

On to step 5:
499 divided by 51 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 679.0
Subtract 459 from 499 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 51

Let's proceed to step 6:
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: 6797.0
If we subtract 357 from 402, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 6797.8
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
When dividing 420 by 51, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6797.88
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 6797.88 and a remainder of 0.012.
