502331 divided by 51 
The aim is to understand the frequency of 51 in 502331.

Let's proceed to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 51

On to step 2:
If we divide 50 by 51, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 51

Let's proceed to step 3:
The number 51 fits into 502 9 times, leaving a remainder of 43.
The next digit of our result is 9. 
Result so far: 9.0
If we take 459 away from 502, we end up with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 51

Let's proceed to step 4:
When dividing 433 by 51, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 408 away from 433, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 51

Moving on to step 5:
51 goes into 253 4 times with a remainder of 49.
The next digit of our result is 4. 
Result so far: 984.0
Subtracting 204 from 253 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 51

Step 6:
The number 51 fits into 491 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 9849.0
Subtract 459 from 491 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
51 goes into 320 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 9849.6
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 9849.62
Subtract 102 from 140 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
When dividing 380 by 51, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 9849.627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
If we divide 230 by 51, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 9849.6274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
51 can be fit into 260 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 9849.62745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 51, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 9849.62745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9849.6274509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 14:
51 goes into 410 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 9849.62745098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 9849.62745098 with a remaining 2e-09.
