99951 ÷ 18 
We want to divide 99951 by 18.

Advancing to step 1:
When dividing 9 by 18, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 18

On to step 2:
18 can be fit into 99 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 90 from 99 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 18

Advancing to step 3:
When dividing 99 by 18, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we take 90 away from 99, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 18

Let's proceed to step 4:
18 goes into 95 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 555.0
If we subtract 90 from 95, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 18

On to step 5:
18 can be fit into 51 2 times, resulting in a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 5552.0
The remainder is 15 after subtracting 36 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 6:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 5552.8
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 18, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 5552.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5552.833
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 5552.833 and a remainder of 0.0006.
