We look at the division of 149435 by 72 
The aim is to understand the frequency of 72 in 149435.

Let's proceed to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 72

Step 2:
72 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 72

On to step 3:
72 goes into 149 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 144 from 149 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 72

On to step 4:
54 divided by 72 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 72

Step 5:
543 divided by 72 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 207.0
Deduct 504 from 543 and we're left with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 72

Step 6:
If we divide 395 by 72, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2075.0
The remainder is 35 after subtracting 360 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
72 goes into 350 4 times with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 2075.4
Subtract 288 from 350 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
620 divided by 72 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 2075.48
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
If we divide 440 by 72, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2075.486
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 72 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 2075.4861
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 2075.48611
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 2075.48611 with a balance of 8e-06.
