2247 ÷ 72 
The aim is to understand the frequency of 72 in 2247.

Step 1:
If we divide 2 by 72, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 72

Going ahead to step 2:
22 divided by 72 is 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 72

Moving on to step 3:
72 goes into 224 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 216 away from 224, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 72

Step 4:
72 goes into 87 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 72 from 87, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 5:
150 divided by 72 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 31.2
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
When dividing 60 by 72, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 31.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
600 divided by 72 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 31.208
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 72, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 31.2083
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 31.20833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 31.20833 with a remainder of 2.4e-05.
