We look at the division of 72170882 by 800 
Let's see how many times 800 fits into 72170882.

Advancing to step 1:
When dividing 7 by 800, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 800

Moving on to step 2:
800 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 800

Going ahead to step 3:
721 divided by 800 is 0 with a remainder of 721.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 721 and we're left with 721.
Append the next digit (7) from the dividend to 721 and continue with: 7217 / 800

Advancing to step 4:
7217 divided by 800 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7200 from 7217 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 800

Step 5:
170 divided by 800 is 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 170 leaves us with 170.
Include the next digit (8) from the dividend after 170, then repeat: 1708 / 800

Let's proceed to step 6:
800 can be fit into 1708 2 times, resulting in a remainder of 108.
The next digit of our result is 2. 
Result so far: 902.0
Subtracting 1600 from 1708 leaves us with 108.
Grab the next digit (8) from the dividend, add it to 108, then carry on: 1088 / 800

Step 7:
The number 800 fits into 1088 1 times, leaving a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 9021.0
Deduct 800 from 1088 and we're left with 288.
Include the next digit (2) from the dividend after 288, then repeat: 2882 / 800

Advancing to step 8:
800 goes into 2882 3 times with a remainder of 482.
Use 3 as the next digit of our solution. 
Result so far: 90213.0
If we take 2400 away from 2882, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 9:
The number 800 fits into 4820 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 90213.6
Subtracting 4800 from 4820 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
800 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 90213.6
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
2000 divided by 800 is 2 with a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 90213.602
If we take 1600 away from 2000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
When dividing 4000 by 800, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 90213.6025
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90213.6025
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
0 divided by 800 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90213.6025
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 90213.6025, with a leftover of 0.0.
