We look at the division of 223538 by 69 
The aim is to understand the frequency of 69 in 223538.

On to step 1:
69 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 69

On to step 2:
The number 69 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 69

Step 3:
223 divided by 69 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 207 away from 223, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 69

Going ahead to step 4:
The number 69 fits into 165 2 times, leaving a remainder of 27.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 138 from 165, we get 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 69

Moving on to step 5:
When dividing 273 by 69, we get 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 323.0
The remainder is 66 after subtracting 207 from 273.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 69

Advancing to step 6:
The number 69 fits into 668 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 3239.0
If we take 621 away from 668, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
69 can be fit into 470 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 3239.6
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.

Moving on to step 8:
560 divided by 69 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3239.68
If we take 552 away from 560, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 69, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 3239.681
If we take 69 away from 80, we end up with 11.
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 10:
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: 3239.6811
Deduct 69 from 110 and we're left 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.

Our division results in 3239.6811 with a remaining 0.00041.
