We look at the division of 1668502 by 72 
We want to figure out the number of times 1668502 can be divided by 72.

Let's proceed to step 1:
72 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 72

Going ahead to step 2:
When dividing 16 by 72, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 72

Let's proceed to step 3:
If we divide 166 by 72, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 144 from 166, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 72

Step 4:
228 divided by 72 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 12 after subtracting 216 from 228.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 72

On to step 5:
If we divide 125 by 72, we get 1 and a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 231.0
The remainder is 53 after subtracting 72 from 125.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 72

Step 6:
530 divided by 72 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 2317.0
If we take 504 away from 530, we end up with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 72

Advancing to step 7:
262 divided by 72 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 23173.0
The remainder is 46 after subtracting 216 from 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
When dividing 460 by 72, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 23173.6
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
72 goes into 280 3 times with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 23173.63
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 23173.638
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
72 goes into 640 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 23173.6388
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 23173.6388 with a remaining 0.00064.
