Let's divide 538550 by 51
The aim is to understand the frequency of 51 in 538550.

Going ahead 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
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 51

Advancing to step 2:
51 can be fit into 53 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 53 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 51

Moving on to step 3:
51 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 51

Moving on to step 4:
51 can be fit into 285 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 255 from 285 leaves us with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 51

Moving on to step 5:
The number 51 fits into 305 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1055.0
If we subtract 255 from 305, we get 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 51

Step 6:
If we divide 500 by 51, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 10559.0
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.

Advancing to step 7:
410 divided by 51 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 10559.8
Subtracting 408 from 410 leaves us 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.

On to step 8:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10559.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 10559.803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
51 can be fit into 470 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 10559.8039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
If we divide 110 by 51, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 10559.80392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 10559.803921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
If we divide 290 by 51, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 10559.8039215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 10559.80392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 10559.80392156 with a balance of 4.4e-08.
