We divide 145319 by 72
The aim is to understand the frequency of 72 in 145319.

Moving on to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 72

On to step 2:
When dividing 14 by 72, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 72

Let's proceed to step 3:
The number 72 fits into 145 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 144 from 145 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 72

On to step 4:
13 divided by 72 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 13, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 72

Let's proceed to step 5:
The number 72 fits into 131 1 times, leaving a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we take 72 away from 131, we end up with 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 72

Going ahead to step 6:
72 goes into 599 8 times with a remainder of 23.
The next digit of our result is 8. 
Result so far: 2018.0
If we subtract 576 from 599, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
If we divide 230 by 72, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2018.3
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 72, we get 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 2018.31
Subtracting 72 from 140 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
72 can be fit into 680 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 2018.319
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 72, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 2018.3194
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
If we divide 320 by 72, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2018.31944
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 2018.31944 and a remainder of 3.2e-05.
