Let's divide 448416 by 72
The aim is to understand the frequency of 72 in 448416.

Going ahead to step 1:
4 divided by 72 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 72

Step 2:
44 divided by 72 is 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 72

Let's proceed to step 3:
If we divide 448 by 72, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 432 from 448 and we're left with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 72

Advancing to step 4:
72 can be fit into 164 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 144 from 164, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 72

Advancing to step 5:
72 goes into 201 2 times with a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 622.0
Deduct 144 from 201 and we're left with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 72

Going ahead to step 6:
72 can be fit into 576 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 6228.0
If we subtract 576 from 576, we 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.

Going ahead to step 7:
The number 72 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6228.0
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
When dividing 0 by 72, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6228.0
If we subtract 0 from 0, we 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.

The final result is 6228.0 with a remainder of 0.0.
