Let's divide 69604 by 72
The aim is to understand the frequency of 72 in 69604.

Going ahead to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 72

On to step 2:
When dividing 69 by 72, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 72

Moving on to step 3:
The number 72 fits into 696 9 times, leaving a remainder of 48.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 48 after subtracting 648 from 696.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 72

Advancing to step 4:
If we divide 480 by 72, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtracting 432 from 480 leaves us with 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 72

Moving on to step 5:
If we divide 484 by 72, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 966.0
Subtracting 432 from 484 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 6:
When dividing 520 by 72, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 966.7
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 966.72
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
72 can be fit into 160 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 966.722
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 966.722 with a remainder of 0.0016.
