922111 divided by 72 
The aim is to understand the frequency of 72 in 922111.

On to step 1:
9 divided by 72 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 72

Moving on to step 2:
72 can be fit into 92 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 92 leaves us with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 72

Moving on to step 3:
72 can be fit into 202 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 144 from 202 to get 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 72

Moving on to step 4:
581 divided by 72 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 576 from 581 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 72

Advancing to step 5:
If we divide 51 by 72, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 1280.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 72

Let's proceed to step 6:
511 divided by 72 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 12807.0
Deduct 504 from 511 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
72 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 12807.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
The number 72 fits into 700 9 times, leaving a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 12807.09
Subtracting 648 from 700 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.

Step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 12807.097
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.

Advancing to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12807.0972
Deduct 144 from 160 and we're left 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 11:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12807.09722
If we subtract 144 from 160, we get 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 12807.09722 with a remainder of 1.6e-05.
