We're dividing 320427 by 72 
We want to figure out the number of times 320427 can be divided by 72.

Let's proceed to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 72

On to step 2:
When dividing 32 by 72, we get 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 72

Moving on to step 3:
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: 4.0
Deduct 288 from 320 and we're left with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 72

Step 4:
72 goes into 324 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 288 from 324 to get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 72

Advancing to step 5:
When dividing 362 by 72, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Deduct 360 from 362 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 72

Step 6:
27 divided by 72 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 4450.0
If we take 0 away from 27, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
The number 72 fits into 270 3 times, leaving a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 4450.3
The remainder is 54 after subtracting 216 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
72 can be fit into 540 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 4450.37
Subtracting 504 from 540 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 9:
If we divide 360 by 72, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4450.375
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 10:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4450.375
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 11:
When dividing 0 by 72, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4450.375
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.

Our division results in 4450.375 with a remaining 0.0.
