We look at the division of 318749 by 69 
The aim is to understand the frequency of 69 in 318749.

On to step 1:
69 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 69

Advancing to step 2:
If we divide 31 by 69, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 69

Going ahead to step 3:
318 divided by 69 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 276 from 318 to get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 69

On to step 4:
69 goes into 427 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 414 from 427 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 69

On to step 5:
The number 69 fits into 134 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
The remainder is 65 after subtracting 69 from 134.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 69

Going ahead to step 6:
69 can be fit into 659 9 times, resulting in a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 4619.0
The remainder is 38 after subtracting 621 from 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 69 fits into 380 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4619.5
The remainder is 35 after subtracting 345 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
If we divide 350 by 69, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4619.55
Subtract 345 from 350 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 4619.55 with a remainder of 0.005.
