We're dividing 169441 by 51 
The aim is to understand the frequency of 51 in 169441.

Step 1:
51 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 51

Step 2:
16 divided by 51 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 51

Advancing to step 3:
If we divide 169 by 51, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 153 away from 169, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 51

Moving on to step 4:
51 goes into 164 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 153 from 164 leaves us with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 51

Going ahead to step 5:
When dividing 114 by 51, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 332.0
The remainder is 12 after subtracting 102 from 114.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 51

Let's proceed to step 6:
When dividing 121 by 51, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 3322.0
If we take 102 away from 121, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
190 divided by 51 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 3322.3
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
370 divided by 51 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3322.37
Subtracting 357 from 370 leaves us 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.

Moving on to step 9:
130 divided by 51 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 3322.372
Subtracting 102 from 130 leaves us 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.

Step 10:
51 goes into 280 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3322.3725
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.

Advancing to step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 3322.37254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 3322.372549
Subtracting 459 from 460 leaves us 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:
When dividing 10 by 51, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3322.372549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
51 can be fit into 100 1 times, resulting in a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3322.37254901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 3322.37254901 with a remainder of 4.9e-08.
