We look at the division of 121818 by 72 
Let's see how many times 72 fits into 121818.

Advancing to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 72

Let's proceed to step 2:
72 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 72

Going ahead to step 3:
121 divided by 72 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 72 from 121 and we're left with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 72

On to step 4:
72 goes into 498 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 66 after subtracting 432 from 498.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 72

Moving on to step 5:
661 divided by 72 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 169.0
Deduct 648 from 661 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 72

Advancing to step 6:
The number 72 fits into 138 1 times, leaving a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.0
Subtracting 72 from 138 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
When dividing 660 by 72, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 1691.9
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 72 fits into 120 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.91
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 72 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 1691.916
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
If we divide 480 by 72, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 1691.9166
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 1691.9166 with a remaining 0.00048.
