We look at the division of 592789 by 72 
The aim is to understand the frequency of 72 in 592789.

Let's proceed to step 1:
When dividing 5 by 72, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 72

On to step 2:
When dividing 59 by 72, we get 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 72

Step 3:
72 goes into 592 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 16 after subtracting 576 from 592.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 72

Advancing to step 4:
72 can be fit into 167 2 times, resulting in a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 144 from 167, we get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 72

Let's proceed to step 5:
When dividing 238 by 72, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 823.0
Deduct 216 from 238 and we're left with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 72

On to step 6:
If we divide 229 by 72, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 8233.0
If we take 216 away from 229, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 72, we get 1 and a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 8233.1
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 8:
72 goes into 580 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8233.18
Subtracting 576 from 580 leaves us 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.

Let's proceed to step 9:
72 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8233.18
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 8233.1805
Subtracting 360 from 400 leaves us with 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 11:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 8233.18055
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.

After the division, we end up with 8233.18055 and a remainder of 4e-05.
