Let's divide 85905 by 72
The aim is to understand the frequency of 72 in 85905.

Let's proceed to step 1:
72 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 72

Advancing to step 2:
72 can be fit into 85 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 72 from 85, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 72

Moving on to step 3:
When dividing 139 by 72, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 72 from 139 and we're left with 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 72

Going ahead to step 4:
When dividing 670 by 72, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 648 from 670, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 72

Moving on to step 5:
When dividing 225 by 72, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1193.0
The remainder is 9 after subtracting 216 from 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
72 can be fit into 90 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1193.1
Deduct 72 from 90 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 72 fits into 180 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 1193.12
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.

Moving on to step 8:
360 divided by 72 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1193.125
Subtract 360 from 360 to 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.

Step 9:
If we divide 0 by 72, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1193.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
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: 1193.125
Deduct 0 from 0 and we're left 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.

After the division, we end up with 1193.125 and a remainder of 0.0.
