We're dividing 79147840 by 800 
We want to divide 79147840 by 800.

Step 1:
800 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 800

Let's proceed to step 2:
79 divided by 800 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 800

Advancing to step 3:
800 can be fit into 791 0 times, resulting in a remainder of 791.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 791 to get 791.
Append the next digit (4) from the dividend to 791 and continue with: 7914 / 800

Going ahead to step 4:
When dividing 7914 by 800, we get 9 with a remainder of 714.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 714 after subtracting 7200 from 7914.
Include the next digit (7) from the dividend after 714, then repeat: 7147 / 800

Step 5:
7147 divided by 800 is 8 with a remainder of 747.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 6400 from 7147 to get 747.
Grab the next digit (8) from the dividend, add it to 747, then carry on: 7478 / 800

Going ahead to step 6:
800 can be fit into 7478 9 times, resulting in a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 989.0
If we subtract 7200 from 7478, we get 278.
Include the next digit (4) from the dividend after 278, then repeat: 2784 / 800

Let's proceed to step 7:
800 goes into 2784 3 times with a remainder of 384.
Put 3 as the next digit of the answer. 
Result so far: 9893.0
Deduct 2400 from 2784 and we're left with 384.
Include the next digit (0) from the dividend after 384, then repeat: 3840 / 800

Advancing to step 8:
When dividing 3840 by 800, we get 4 with a remainder of 640.
Put 4 as the next digit of the answer. 
Result so far: 98934.0
Subtracting 3200 from 3840 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 9:
6400 divided by 800 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 98934.8
If we subtract 6400 from 6400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 98934.8
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.

On to step 11:
If we divide 0 by 800, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 98934.8
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.

Our division results in 98934.8 with a remaining 0.0.
