Let's divide 266188 by 51
The aim is to understand the frequency of 51 in 266188.

Advancing to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 51

On to step 2:
26 divided by 51 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 51

On to step 3:
If we divide 266 by 51, we get 5 and a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
If we take 255 away from 266, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 51

Step 4:
111 divided by 51 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 102 from 111, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 51

Step 5:
51 goes into 98 1 times with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
Deduct 51 from 98 and we're left with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 51

Moving on to step 6:
51 can be fit into 478 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 5219.0
Subtract 459 from 478 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 51, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 5219.3
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 51, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5219.37
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
51 goes into 130 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 5219.372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
51 goes into 280 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5219.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
51 goes into 250 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 5219.37254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
51 goes into 460 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 5219.372549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
If we divide 10 by 51, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 5219.372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
If we divide 100 by 51, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 5219.37254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 5219.37254901 with a balance of 4.9e-08.
