We're dividing 345560 by 69 
The aim is to understand the frequency of 69 in 345560.

Going ahead to step 1:
The number 69 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 69

Let's proceed to step 2:
The number 69 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 69

On to step 3:
345 divided by 69 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 345 from 345 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 69

Moving on to step 4:
69 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 69

Going ahead to step 5:
If we divide 56 by 69, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 500.0
If we subtract 0 from 56, we get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 69

Step 6:
If we divide 560 by 69, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 5008.0
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.

Step 7:
69 can be fit into 80 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 5008.1
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
110 divided by 69 is 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 5008.11
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.

The final result is 5008.11 with a remainder of 0.041.
