Let's divide 154478 by 72
The aim is to understand the frequency of 72 in 154478.

Step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 72

On to step 2:
If we divide 15 by 72, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 72

On to step 3:
If we divide 154 by 72, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 144 from 154, we get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 72

On to step 4:
If we divide 104 by 72, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 72 from 104 leaves us with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 72

Step 5:
When dividing 327 by 72, we get 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtract 288 from 327 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 72

Going ahead to step 6:
72 goes into 398 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 2145.0
Subtracting 360 from 398 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
If we divide 380 by 72, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2145.5
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 72, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 2145.52
Subtracting 144 from 200 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
72 goes into 560 7 times with a remainder of 56.
The next digit of our result is 7. 
Result so far: 2145.527
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 72 is 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 2145.5277
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 2145.5277, with a leftover of 0.00056.
