We divide 86240458 by 800
We want to divide 86240458 by 800.

Let's proceed to step 1:
8 divided by 800 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 800

Going ahead to step 2:
If we divide 86 by 800, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 800

Advancing to step 3:
When dividing 862 by 800, we get 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 800 from 862, we get 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 800

Step 4:
800 goes into 624 0 times with a remainder of 624.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 624 after subtracting 0 from 624.
Include the next digit (0) from the dividend after 624, then repeat: 6240 / 800

On to step 5:
The number 800 fits into 6240 7 times, leaving a remainder of 640.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 5600 away from 6240, we end up with 640.
Append the next digit (4) from the dividend to 640 and continue with: 6404 / 800

Moving on to step 6:
800 can be fit into 6404 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 1078.0
Subtracting 6400 from 6404 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 800

Moving on to step 7:
When dividing 45 by 800, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 10780.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 800

Moving on to step 8:
800 goes into 458 0 times with a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 107800.0
If we take 0 away from 458, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 9:
If we divide 4580 by 800, we get 5 and a remainder of 580.
Put 5 as the next digit of the answer. 
Result so far: 107800.5
Deduct 4000 from 4580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 10:
800 can be fit into 5800 7 times, resulting in a remainder of 200.
Write down 7 as next digit of the result. 
Result so far: 107800.57
If we take 5600 away from 5800, 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.

Going ahead 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: 107800.572
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.

Going ahead to step 12:
When dividing 4000 by 800, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 107800.5725
Deduct 4000 from 4000 and we're left 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.

Let's proceed to step 13:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 107800.5725
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.

Advancing to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 107800.5725
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.

In conclusion, the division gives 107800.5725 with a balance of 0.0.
