78738280 divided by 800 
We want to divide 78738280 by 800.

Going ahead to step 1:
800 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 800

On to step 2:
800 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 800

Going ahead to step 3:
When dividing 787 by 800, we get 0 with a remainder of 787.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 787 to get 787.
Fetch the next digit (3) from the dividend, attach it to 787 and continue: 7873 / 800

Advancing to step 4:
7873 divided by 800 is 9 with a remainder of 673.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7200 from 7873, we get 673.
Fetch the next digit (8) from the dividend, attach it to 673 and continue: 6738 / 800

Step 5:
800 can be fit into 6738 8 times, resulting in a remainder of 338.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 6400 away from 6738, we end up with 338.
Include the next digit (2) from the dividend after 338, then repeat: 3382 / 800

On to step 6:
If we divide 3382 by 800, we get 4 and a remainder of 182.
Use 4 as the next digit of our solution. 
Result so far: 984.0
Subtract 3200 from 3382 to get 182.
Append the next digit (8) from the dividend to 182 and continue with: 1828 / 800

On to step 7:
800 goes into 1828 2 times with a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 9842.0
Subtracting 1600 from 1828 leaves us with 228.
Grab the next digit (0) from the dividend, add it to 228, then carry on: 2280 / 800

Step 8:
2280 divided by 800 is 2 with a remainder of 680.
The number 2 becomes the next digit in our result. 
Result so far: 98422.0
If we subtract 1600 from 2280, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 9:
When dividing 6800 by 800, we get 8 with a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 98422.8
If we take 6400 away from 6800, 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.

On to step 10:
800 goes into 4000 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 98422.85
If we subtract 4000 from 4000, 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.

Advancing to step 11:
800 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 98422.85
If we take 0 away from 0, we end up 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.

Step 12:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 98422.85
If we take 0 away from 0, we end up 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 98422.85 with a remaining 0.0.
