345416 divided by 72 
The aim is to understand the frequency of 72 in 345416.

On to step 1:
72 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 72

On to step 2:
72 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 72

On to step 3:
If we divide 345 by 72, we get 4 and a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 288 away from 345, we end up with 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 72

Going ahead to step 4:
72 goes into 574 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 504 away from 574, we end up with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 72

On to step 5:
72 can be fit into 701 9 times, resulting in a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 479.0
If we subtract 648 from 701, we get 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 72

Let's proceed to step 6:
72 can be fit into 536 7 times, resulting in a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 4797.0
Subtracting 504 from 536 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.

On to step 7:
When dividing 320 by 72, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 4797.4
If we take 288 away from 320, we end up 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.

Going ahead to step 8:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4797.44
If we subtract 288 from 320, 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.

The final outcome is 4797.44, with a leftover of 0.032.
