We're dividing 84118 by 72 
The aim is to understand the frequency of 72 in 84118.

Moving on to step 1:
8 divided by 72 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 72

Step 2:
If we divide 84 by 72, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 72 away from 84, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 72

Moving on to step 3:
If we divide 121 by 72, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 72 from 121, we get 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 72

Advancing to step 4:
491 divided by 72 is 6 with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 432 from 491 and we're left with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 72

On to step 5:
The number 72 fits into 598 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 1168.0
If we subtract 576 from 598, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 6:
The number 72 fits into 220 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1168.3
Deduct 216 from 220 and we're left 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.

Step 7:
If we divide 40 by 72, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 1168.3
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.

Going ahead to step 8:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1168.305
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.

Step 9:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1168.3055
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 1168.3055 and a remainder of 0.0004.
