We divide 77877 by 18
We want to divide 77877 by 18.

Advancing to step 1:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 18

Going ahead to step 2:
If we divide 77 by 18, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 5 after subtracting 72 from 77.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 18

Let's proceed to step 3:
58 divided by 18 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 54 from 58 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 18

Let's proceed to step 4:
When dividing 47 by 18, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 432.0
If we subtract 36 from 47, we get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 18

On to step 5:
18 goes into 117 6 times with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 4326.0
The remainder is 9 after subtracting 108 from 117.
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:
18 goes into 90 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4326.5
Deduct 90 from 90 and we're left 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.

On to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4326.5
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.

Let's proceed to step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4326.5
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 4326.5 with a remainder of 0.0.
