We're dividing 87809 by 10 
We want to divide 87809 by 10.

On to step 1:
10 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 10

Step 2:
When dividing 87 by 10, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 80 from 87 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 10

Going ahead to step 3:
10 can be fit into 78 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 70 from 78, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 10

Advancing to step 4:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 878.0
The remainder is 0 after subtracting 80 from 80.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 10

Advancing to step 5:
10 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 8780.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
When dividing 90 by 10, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 8780.9
Subtracting 90 from 90 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.

Going ahead to step 7:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8780.9
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.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8780.9
If we subtract 0 from 0, 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.

The final result is 8780.9 with a remainder of 0.0.
