20961004 ÷ 18 
Our goal is to divide 20961004 by 18.

Let's proceed to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 18

Moving on to step 2:
20 divided by 18 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 18 from 20.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 18

Moving on to step 3:
The number 18 fits into 29 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 18 from 29, we get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 18

Step 4:
116 divided by 18 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
The remainder is 8 after subtracting 108 from 116.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 18

Let's proceed to step 5:
81 divided by 18 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 1164.0
Deduct 72 from 81 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 18

Step 6:
90 divided by 18 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11645.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 18

On to step 7:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 116450.0
If we subtract 0 from 0, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 18

Step 8:
If we divide 4 by 18, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1164500.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1164500.2
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.

Moving on to step 10:
If we divide 40 by 18, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1164500.22
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 1164500.22, and the remainder is 0.004.
