Let's divide 808383 by 51
The aim is to understand the frequency of 51 in 808383.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 51

Let's proceed to step 2:
When dividing 80 by 51, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 80 leaves us with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 51

On to step 3:
51 can be fit into 298 5 times, resulting in a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 255 from 298 leaves us with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 51

Let's proceed to step 4:
433 divided by 51 is 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Deduct 408 from 433 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 51

Advancing to step 5:
51 goes into 258 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1585.0
Subtract 255 from 258 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 51

On to step 6:
The number 51 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 15850.0
The remainder is 33 after subtracting 0 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
51 goes into 330 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 15850.6
The remainder is 24 after subtracting 306 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 15850.64
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
360 divided by 51 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 15850.647
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15850.647
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 15850.64705
If we subtract 255 from 300, 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.

Going ahead to step 12:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 15850.647058
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.

Moving on to step 13:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15850.6470588
If we take 408 away from 420, we end up 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.

The quotient of the division is 15850.6470588, and the remainder is 1.2e-07.
