We're dividing 705897 by 72 
The aim is to understand the frequency of 72 in 705897.

Step 1:
7 divided by 72 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 72

Advancing to step 2:
When dividing 70 by 72, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 72

Advancing to step 3:
72 goes into 705 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 648 from 705, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 72

On to step 4:
When dividing 578 by 72, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 576 away from 578, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 72

Going ahead to step 5:
If we divide 29 by 72, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 980.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 72

Step 6:
72 can be fit into 297 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 9804.0
The remainder is 9 after subtracting 288 from 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 72, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 9804.1
The remainder is 18 after subtracting 72 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 72, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 9804.12
Deduct 144 from 180 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
72 can be fit into 360 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9804.125
If we take 360 away from 360, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 72, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9804.125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 72, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9804.125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 9804.125 and a remainder of 0.0.
