We're dividing 991605 by 69 
The aim is to understand the frequency of 69 in 991605.

Step 1:
When dividing 9 by 69, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 69

Moving on to step 2:
If we divide 99 by 69, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 69 from 99 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 69

Moving on to step 3:
If we divide 301 by 69, we get 4 and a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 276 from 301, we get 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 69

Advancing to step 4:
69 goes into 256 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Subtract 207 from 256 to get 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 69

Let's proceed to step 5:
490 divided by 69 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1437.0
Subtracting 483 from 490 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 69

Advancing to step 6:
If we divide 75 by 69, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 14371.0
The remainder is 6 after subtracting 69 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
69 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 14371.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 69, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 14371.08
If we subtract 552 from 600, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 69, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 14371.086
If we subtract 414 from 480, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
69 can be fit into 660 9 times, resulting in a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 14371.0869
Deduct 621 from 660 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
390 divided by 69 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 14371.08695
Deduct 345 from 390 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
The number 69 fits into 450 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 14371.086956
If we take 414 away from 450, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
69 can be fit into 360 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 14371.0869565
Subtract 345 from 360 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
If we divide 150 by 69, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 14371.08695652
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 14371.08695652 with a remaining 1.2e-08.
