872806 ÷ 72 
We want to figure out the number of times 872806 can be divided by 72.

Step 1:
72 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 72

Advancing to step 2:
87 divided by 72 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 72 away from 87, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 72

Advancing to step 3:
152 divided by 72 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 8 after subtracting 144 from 152.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 72

Moving on to step 4:
The number 72 fits into 88 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
The remainder is 16 after subtracting 72 from 88.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 72

Advancing to step 5:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 1212.0
Deduct 144 from 160 and we're left with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 72

Let's proceed to step 6:
72 can be fit into 166 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12122.0
If we subtract 144 from 166, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
The number 72 fits into 220 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 12122.3
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 72, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12122.3
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 72 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 12122.305
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 12122.3055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 12122.3055, with a leftover of 0.0004.
