Let's divide 745442 by 72
The aim is to understand the frequency of 72 in 745442.

On to step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 72

Moving on to step 2:
The number 72 fits into 74 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 74 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 72

On to step 3:
If we divide 25 by 72, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 72

Let's proceed to step 4:
72 goes into 254 3 times with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 103.0
The remainder is 38 after subtracting 216 from 254.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 72

On to step 5:
If we divide 384 by 72, we get 5 and a remainder of 24.
The next digit of our result is 5. 
Result so far: 1035.0
The remainder is 24 after subtracting 360 from 384.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 72

Moving on to step 6:
The number 72 fits into 242 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 10353.0
Subtract 216 from 242 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
260 divided by 72 is 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 10353.3
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10353.36
Deduct 432 from 440 and we're left 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.

Let's proceed to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 10353.361
Subtracting 72 from 80 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.

Moving on to step 10:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10353.3611
Deduct 72 from 80 and we're left 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.

After the division, we end up with 10353.3611 and a remainder of 8e-05.
