225242 divided by 51 
The aim is to understand the frequency of 51 in 225242.

Let's proceed to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 51

Advancing to step 2:
If we divide 22 by 51, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 51

Advancing to step 3:
When dividing 225 by 51, we get 4 with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 21 after subtracting 204 from 225.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 51

Moving on to step 4:
When dividing 212 by 51, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 204 from 212 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 51

Moving on to step 5:
The number 51 fits into 84 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 441.0
Subtract 51 from 84 to get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 51

Moving on to step 6:
51 goes into 332 6 times with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 4416.0
Deduct 306 from 332 and we're left 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.

Let's proceed to step 7:
If we divide 260 by 51, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4416.5
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
51 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4416.5
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.

Step 9:
500 divided by 51 is 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 4416.509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
410 divided by 51 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4416.5098
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 11:
51 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4416.5098
If we subtract 0 from 20, we get 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 12:
51 goes into 200 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 4416.509803
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 13:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4416.5098039
If we subtract 459 from 470, we 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.

Step 14:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 4416.50980392
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.

In conclusion, the division gives 4416.50980392 with a balance of 8e-09.
