We're dividing 368442 by 72 
The aim is to understand the frequency of 72 in 368442.

Going ahead to step 1:
72 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 72

Advancing to step 2:
If we divide 36 by 72, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 72

Going ahead to step 3:
If we divide 368 by 72, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 360 from 368 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 72

Moving on to step 4:
If we divide 84 by 72, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 72 from 84, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 72

Advancing to step 5:
When dividing 124 by 72, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 511.0
The remainder is 52 after subtracting 72 from 124.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 72

Advancing to step 6:
The number 72 fits into 522 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 5117.0
If we subtract 504 from 522, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 72 fits into 180 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 5117.2
Subtracting 144 from 180 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 72, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 5117.25
Subtract 360 from 360 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 72 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5117.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
72 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5117.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5117.25 and a remainder of 0.0.
