We look at the division of 263066 by 51 
The aim is to understand the frequency of 51 in 263066.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 51

Moving on to step 2:
51 goes into 26 0 times with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 51

Let's proceed to step 3:
51 can be fit into 263 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 255 away from 263, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 51

Moving on to step 4:
When dividing 80 by 51, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 51 from 80 to get 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 51

Advancing to step 5:
If we divide 296 by 51, we get 5 and a remainder of 41.
The next digit of our result is 5. 
Result so far: 515.0
Subtract 255 from 296 to get 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 51

Step 6:
51 can be fit into 416 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 5158.0
The remainder is 8 after subtracting 408 from 416.
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 7:
80 divided by 51 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 5158.1
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 8:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5158.15
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
51 goes into 350 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 5158.156
Subtract 306 from 350 to 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.

Let's proceed to step 10:
When dividing 440 by 51, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 5158.1568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 51 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 5158.15686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5158.156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
380 divided by 51 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 5158.1568627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
51 goes into 230 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 5158.15686274
Subtracting 204 from 230 leaves us 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.

The quotient of the division is 5158.15686274, and the remainder is 2.6e-08.
