836286 divided by 72 
We want to figure out the number of times 836286 can be divided by 72.

Step 1:
8 divided by 72 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 72

On to step 2:
If we divide 83 by 72, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 83 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 72

Let's proceed to step 3:
116 divided by 72 is 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 44 after subtracting 72 from 116.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 72

Advancing to step 4:
When dividing 442 by 72, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 432 from 442 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 72

Let's proceed to step 5:
72 goes into 108 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1161.0
If we take 72 away from 108, we end up with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 72

Moving on to step 6:
The number 72 fits into 366 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 11615.0
If we subtract 360 from 366, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 72, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 11615.0
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.

Advancing to step 8:
If we divide 600 by 72, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 11615.08
If we subtract 576 from 600, we 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 9:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 11615.083
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
240 divided by 72 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 11615.0833
If we subtract 216 from 240, we 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.

The final outcome is 11615.0833, with a leftover of 0.00024.
