We divide 811841 by 69
The aim is to understand the frequency of 69 in 811841.

Going ahead to step 1:
If we divide 8 by 69, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 69

Let's proceed to step 2:
If we divide 81 by 69, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 69 from 81 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 69

Let's proceed to step 3:
69 goes into 121 1 times with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 69 from 121 to get 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 69

Advancing to step 4:
69 can be fit into 528 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 117.0
Subtract 483 from 528 to get 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 69

Going ahead to step 5:
69 can be fit into 454 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 1176.0
The remainder is 40 after subtracting 414 from 454.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 69

Moving on to step 6:
If we divide 401 by 69, we get 5 and a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 11765.0
Deduct 345 from 401 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.

Moving on to step 7:
560 divided by 69 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 11765.8
If we subtract 552 from 560, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
69 can be fit into 80 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11765.81
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
The number 69 fits into 110 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11765.811
Subtracting 69 from 110 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 11765.811 and a remainder of 0.0041.
