20925963 ÷ 18 
We're looking to find how many times 18 goes into 20925963.

On to step 1:
When dividing 2 by 18, we get 0 with 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.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 18

Step 2:
If we divide 20 by 18, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 18 from 20 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 18

Let's proceed to step 3:
18 can be fit into 29 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 18 away from 29, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 18

Advancing to step 4:
18 goes into 112 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 116.0
If we take 108 away from 112, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 18

Let's proceed to step 5:
45 divided by 18 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 1162.0
If we subtract 36 from 45, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 18

Moving on to step 6:
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: 11625.0
If we take 90 away from 99, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 18

Moving on to step 7:
When dividing 96 by 18, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 116255.0
If we subtract 90 from 96, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 18

On to step 8:
63 divided by 18 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 1162553.0
Deduct 54 from 63 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 18, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1162553.5
If we subtract 90 from 90, 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 10:
18 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1162553.5
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 11:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1162553.5
If we take 0 away from 0, we end up 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.

The final outcome is 1162553.5, with a leftover of 0.0.
