We look at the division of 35768 by 51 
The aim is to understand the frequency of 51 in 35768.

Step 1:
51 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 51

Advancing to step 2:
51 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 51

Moving on to step 3:
If we divide 357 by 51, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 0 after subtracting 357 from 357.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 51

Advancing to step 4:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 51

Moving on to step 5:
The number 51 fits into 68 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 701.0
Subtracting 51 from 68 leaves us 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.

Advancing to step 6:
170 divided by 51 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 701.3
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.

Moving on to step 7:
170 divided by 51 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 701.33
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.

The quotient of the division is 701.33, and the remainder is 0.017.
