We're dividing 77899 by 10 
Let's see how many times 10 fits into 77899.

On to step 1:
10 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 10

Let's proceed to step 2:
If we divide 77 by 10, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 70 from 77 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 10

Moving on to step 3:
The number 10 fits into 78 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 8 after subtracting 70 from 78.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 10

Let's proceed to step 4:
The number 10 fits into 89 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 778.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 10

Advancing to step 5:
99 divided by 10 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 7789.0
If we take 90 away from 99, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving 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: 7789.9
The remainder is 0 after subtracting 90 from 90.
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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7789.9
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 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7789.9
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 7789.9 with a remaining 0.0.
