We're dividing 172091 by 69 
The aim is to understand the frequency of 69 in 172091.

Moving on to step 1:
1 divided by 69 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 69

Let's proceed to step 2:
69 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 69

Going ahead to step 3:
69 can be fit into 172 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 34 after subtracting 138 from 172.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 69

On to step 4:
If we divide 340 by 69, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 64 after subtracting 276 from 340.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 69

Let's proceed to step 5:
69 goes into 649 9 times with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
If we subtract 621 from 649, we get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 69

On to step 6:
The number 69 fits into 281 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 2494.0
If we take 276 away from 281, 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.

Going ahead to step 7:
If we divide 50 by 69, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 2494.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
If we divide 500 by 69, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 2494.07
The remainder is 17 after subtracting 483 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
69 goes into 170 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2494.072
If we subtract 138 from 170, we 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.

Advancing to step 10:
69 can be fit into 320 4 times, resulting in a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 2494.0724
Subtract 276 from 320 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 11:
The number 69 fits into 440 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 2494.07246
Subtracting 414 from 440 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.

On to step 12:
69 goes into 260 3 times with a remainder of 53.
The next digit of our result is 3. 
Result so far: 2494.072463
Deduct 207 from 260 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 13:
If we divide 530 by 69, we get 7 and a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 2494.0724637
The remainder is 47 after subtracting 483 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
470 divided by 69 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 2494.07246376
Deduct 414 from 470 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 2494.07246376 with a balance of 5.6e-08.
