We look at the division of 71848617 by 800 
We want to figure out the number of times 71848617 can be divided by 800.

Advancing to step 1:
If we divide 7 by 800, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 800

Going ahead to step 2:
If we divide 71 by 800, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 800

Let's proceed to step 3:
If we divide 718 by 800, we get 0 and a remainder of 718.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 718 leaves us with 718.
Grab the next digit (4) from the dividend, add it to 718, then carry on: 7184 / 800

Step 4:
When dividing 7184 by 800, we get 8 with a remainder of 784.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6400 from 7184, we get 784.
Take the next digit (8) from the dividend and append it to 784, then repeat: 7848 / 800

Moving on to step 5:
800 goes into 7848 9 times with a remainder of 648.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 648 after subtracting 7200 from 7848.
Include the next digit (6) from the dividend after 648, then repeat: 6486 / 800

Going ahead to step 6:
When dividing 6486 by 800, we get 8 with a remainder of 86.
The next digit of our result is 8. 
Result so far: 898.0
Subtract 6400 from 6486 to get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 800

Advancing to step 7:
800 can be fit into 861 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 8981.0
If we subtract 800 from 861, we get 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 800

Going ahead to step 8:
When dividing 617 by 800, we get 0 with a remainder of 617.
The number 0 becomes the next digit in our result. 
Result so far: 89810.0
If we subtract 0 from 617, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 9:
When dividing 6170 by 800, we get 7 with a remainder of 570.
Use 7 as the next digit of our solution. 
Result so far: 89810.7
Deduct 5600 from 6170 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 10:
800 goes into 5700 7 times with a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 89810.77
Subtract 5600 from 5700 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 89810.77 with a remaining 0.1.
