64445 ÷ 72 
The aim is to understand the frequency of 72 in 64445.

Going ahead to step 1:
6 divided by 72 is 0 with 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 (4) from the dividend, attach it to 6 and continue: 64 / 72

On to step 2:
72 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 72

Advancing to step 3:
The number 72 fits into 644 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 8.0
If we take 576 away from 644, we end up with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 72

Let's proceed to step 4:
If we divide 684 by 72, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 648 from 684, we get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 72

Let's proceed to step 5:
72 can be fit into 365 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 895.0
The remainder is 5 after subtracting 360 from 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
The number 72 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 895.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
When dividing 500 by 72, we get 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 895.06
Deduct 432 from 500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
72 can be fit into 680 9 times, resulting in a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 895.069
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 895.0694
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 72 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 895.06944
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 895.06944 with a remaining 3.2e-05.
