92821 ÷ 72 
The aim is to understand the frequency of 72 in 92821.

Going ahead to step 1:
If we divide 9 by 72, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 72

Let's proceed to step 2:
72 goes into 92 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 92, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 72

Step 3:
208 divided by 72 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 64 after subtracting 144 from 208.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 72

Moving on to step 4:
The number 72 fits into 642 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we take 576 away from 642, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 72

Going ahead to step 5:
72 can be fit into 661 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 1289.0
Subtract 648 from 661 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 6:
When dividing 130 by 72, we get 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1289.1
Subtract 72 from 130 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
72 can be fit into 580 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1289.18
If we take 576 away from 580, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 72 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1289.18
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1289.1805
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1289.18055
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 1289.18055, with a leftover of 4e-05.
