We look at the division of 813351 by 72 
We want to divide 813351 by 72.

On to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 72

Advancing to step 2:
If we divide 81 by 72, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 72 from 81.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 72

Going ahead to step 3:
72 goes into 93 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 72 from 93 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 72

Let's proceed to step 4:
72 can be fit into 213 2 times, resulting in a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 144 away from 213, we end up with 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 72

On to step 5:
72 goes into 695 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 1129.0
Subtract 648 from 695 to get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 72

Let's proceed to step 6:
When dividing 471 by 72, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 11296.0
If we take 432 away from 471, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
72 goes into 390 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11296.5
Deduct 360 from 390 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
72 can be fit into 300 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 11296.54
If we take 288 away from 300, we end up 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.

Moving on to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11296.541
Subtracting 72 from 120 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.

Step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 11296.5416
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.

On to step 11:
When dividing 480 by 72, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 11296.54166
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 11296.54166 with a remaining 4.8e-05.
