We divide 19651 by 18
We're looking to find how many times 18 goes into 19651.

On to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

On to step 2:
18 goes into 19 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 18

Going ahead to step 3:
18 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 18

Let's proceed to step 4:
If we divide 165 by 18, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 3 after subtracting 162 from 165.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 18

On to step 5:
31 divided by 18 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1091.0
Deduct 18 from 31 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
The number 18 fits into 130 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1091.7
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 18 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1091.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1091.722
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 1091.722 and a remainder of 0.0004.
