991819 ÷ 18 
Let's see how many times 18 fits into 991819.

Let's proceed to step 1:
18 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 18

Advancing to step 2:
If we divide 99 by 18, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
If we take 90 away from 99, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 18

On to step 3:
91 divided by 18 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 90 from 91 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 18

Step 4:
The number 18 fits into 18 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 18

Step 5:
18 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 5510.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

Let's proceed to step 6:
If we divide 19 by 18, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 55101.0
If we subtract 18 from 19, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 18, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 55101.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 55101.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 55101.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 55101.055 and a remainder of 0.001.
