922448 ÷ 72 
The aim is to understand the frequency of 72 in 922448.

Advancing to step 1:
72 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 72

Going ahead to step 2:
If we divide 92 by 72, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 72 from 92 leaves us with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 72

Advancing to step 3:
The number 72 fits into 202 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 144 from 202 to get 58.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 72

Advancing to step 4:
The number 72 fits into 584 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 128.0
Deduct 576 from 584 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 72

On to step 5:
72 can be fit into 84 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1281.0
If we take 72 away from 84, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 72

On to step 6:
128 divided by 72 is 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 12811.0
Deduct 72 from 128 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:
When dividing 560 by 72, we get 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 12811.7
Deduct 504 from 560 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.

Advancing to step 8:
560 divided by 72 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 12811.77
Subtracting 504 from 560 leaves us 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.

The final result is 12811.77 with a remainder of 0.056.
