86447493 ÷ 800 
We're looking to find how many times 800 goes into 86447493.

Advancing to step 1:
8 divided by 800 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 800

Moving on to step 2:
800 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 800

Advancing to step 3:
864 divided by 800 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 800 from 864 leaves us with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 800

Step 4:
The number 800 fits into 644 0 times, leaving a remainder of 644.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 644 leaves us with 644.
Bring next digit (7) of the dividend behind the 644 and repeat the process: 6447 / 800

On to step 5:
If we divide 6447 by 800, we get 8 and a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we take 6400 away from 6447, we end up with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 800

Let's proceed to step 6:
When dividing 474 by 800, we get 0 with a remainder of 474.
Write down 0 as next digit of the result. 
Result so far: 1080.0
Subtract 0 from 474 to get 474.
Append the next digit (9) from the dividend to 474 and continue with: 4749 / 800

Going ahead to step 7:
800 goes into 4749 5 times with a remainder of 749.
The number 5 becomes the next digit in our result. 
Result so far: 10805.0
If we subtract 4000 from 4749, we get 749.
Grab the next digit (3) from the dividend, add it to 749, then carry on: 7493 / 800

Advancing to step 8:
If we divide 7493 by 800, we get 9 and a remainder of 293.
The number 9 becomes the next digit in our result. 
Result so far: 108059.0
If we subtract 7200 from 7493, we get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 9:
2930 divided by 800 is 3 with a remainder of 530.
The next digit of our result is 3. 
Result so far: 108059.3
If we subtract 2400 from 2930, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 10:
800 can be fit into 5300 6 times, resulting in a remainder of 500.
The number 6 becomes the next digit in our result. 
Result so far: 108059.36
Subtract 4800 from 5300 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
800 can be fit into 5000 6 times, resulting in a remainder of 200.
The next digit of our result is 6. 
Result so far: 108059.366
If we take 4800 away from 5000, 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.

In conclusion, the division gives 108059.366 with a balance of 0.02.
