210903 divided by 72 
We want to figure out the number of times 210903 can be divided by 72.

Let's proceed to step 1:
The number 72 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 72

On to step 2:
72 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 72

On to step 3:
72 can be fit into 210 2 times, resulting in a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 144 from 210 to get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 72

Moving on to step 4:
When dividing 669 by 72, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 21 after subtracting 648 from 669.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 72

Advancing to step 5:
If we divide 210 by 72, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
The remainder is 66 after subtracting 144 from 210.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 72

Going ahead to step 6:
72 can be fit into 663 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 2929.0
Subtract 648 from 663 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
150 divided by 72 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2929.2
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
72 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2929.2
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
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: 2929.208
Subtracting 576 from 600 leaves us 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.

On to step 10:
72 goes into 240 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2929.2083
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.

Going ahead to step 11:
240 divided by 72 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 2929.20833
Subtracting 216 from 240 leaves us 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 2929.20833 and a remainder of 2.4e-05.
