We're dividing 10488446 by 800 
Our goal is to divide 10488446 by 800.

Let's proceed to step 1:
1 divided by 800 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 800

On to step 2:
The number 800 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 800

On to step 3:
The number 800 fits into 104 0 times, leaving a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 800

Going ahead to step 4:
The number 800 fits into 1048 1 times, leaving a remainder of 248.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 800 from 1048 and we're left with 248.
Bring next digit (8) of the dividend behind the 248 and repeat the process: 2488 / 800

Moving on to step 5:
800 goes into 2488 3 times with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 2400 away from 2488, we end up with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 800

Advancing to step 6:
If we divide 884 by 800, we get 1 and a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 131.0
The remainder is 84 after subtracting 800 from 884.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 800

Advancing to step 7:
844 divided by 800 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1311.0
If we take 800 away from 844, we end up with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 800

Going ahead to step 8:
446 divided by 800 is 0 with a remainder of 446.
Record the quotient 0 as the next digit in the result. 
Result so far: 13110.0
Subtract 0 from 446 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 9:
800 goes into 4460 5 times with a remainder of 460.
Write down 5 as next digit of the result. 
Result so far: 13110.5
If we subtract 4000 from 4460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
If we divide 4600 by 800, we get 5 and a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 13110.55
Subtracting 4000 from 4600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 13110.55 with a remainder of 0.6.
