We look at the division of 494124 by 51 
The aim is to understand the frequency of 51 in 494124.

Let's proceed to step 1:
4 divided by 51 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 51

Step 2:
If we divide 49 by 51, we get 0 and a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 51

Moving on to step 3:
51 can be fit into 494 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 459 from 494, we get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 51

On to step 4:
51 goes into 351 6 times with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 306 from 351 to get 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 51

Moving on to step 5:
The number 51 fits into 452 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 968.0
The remainder is 44 after subtracting 408 from 452.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 51

On to step 6:
51 goes into 444 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 9688.0
The remainder is 36 after subtracting 408 from 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 51 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 9688.7
Subtract 357 from 360 to 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.

Step 8:
When dividing 30 by 51, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 9688.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 51, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 9688.705
Subtract 255 from 300 to 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.

Advancing to step 10:
51 goes into 450 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9688.7058
Subtracting 408 from 450 leaves us 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 11:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 9688.70588
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.

Our division results in 9688.70588 with a remaining 1.2e-05.
