We're dividing 26921 by 51 
The aim is to understand the frequency of 51 in 26921.

On to step 1:
51 goes into 2 0 times with 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.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 51

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.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 51

Advancing to step 3:
If we divide 269 by 51, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 255 away from 269, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 51

Let's proceed to step 4:
51 goes into 142 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 102 from 142 leaves us with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 51

Going ahead to step 5:
When dividing 401 by 51, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 527.0
Subtract 357 from 401 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.

Going ahead to step 6:
440 divided by 51 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 527.8
Deduct 408 from 440 and we're left with 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 7:
When dividing 320 by 51, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 527.86
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.

Advancing to step 8:
51 can be fit into 140 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 527.862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
380 divided by 51 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 527.8627
If we subtract 357 from 380, we get 23.
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 10:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 527.86274
If we take 204 away from 230, we end up 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 11:
260 divided by 51 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 527.862745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
51 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 527.862745
If we take 0 away from 50, we end up 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 13:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 527.86274509
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.

The final outcome is 527.86274509, with a leftover of 4.1e-08.
