We look at the division of 223620 by 72 
We want to figure out the number of times 223620 can be divided by 72.

Step 1:
72 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 72

Moving on to step 2:
When dividing 22 by 72, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 72

Going ahead to step 3:
The number 72 fits into 223 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 216 from 223 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 72

Going ahead to step 4:
76 divided by 72 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 72 from 76 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 72

Let's proceed to step 5:
The number 72 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 72

Let's proceed to step 6:
If we divide 420 by 72, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 3105.0
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3105.8
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3105.83
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 3105.833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3105.833 and a remainder of 0.0024.
