266450 ÷ 51 
The aim is to understand the frequency of 51 in 266450.

Let's proceed to step 1:
51 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 51

Going ahead to step 2:
The number 51 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 51

Going ahead to step 3:
51 goes into 266 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 255 away from 266, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 51

Let's proceed to step 4:
114 divided by 51 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 12 after subtracting 102 from 114.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 51

Step 5:
51 goes into 125 2 times with a remainder of 23.
The next digit of our result is 2. 
Result so far: 522.0
Subtracting 102 from 125 leaves us with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 51

Going ahead to step 6:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 5224.0
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 5224.5
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.

Moving on to step 8:
50 divided by 51 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5224.5
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.

Moving on to step 9:
If we divide 500 by 51, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 5224.509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
When dividing 410 by 51, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5224.5098
Deduct 408 from 410 and we're left 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 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5224.5098
Deduct 0 from 20 and we're left 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.

Moving on to step 12:
51 goes into 200 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 5224.509803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 5224.5098039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
110 divided by 51 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5224.50980392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 5224.50980392, with a leftover of 8e-09.
