22591664 ÷ 18 
We're looking to find how many times 18 goes into 22591664.

Advancing to step 1:
2 divided by 18 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 18

Going ahead to step 2:
18 goes into 22 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 18 from 22.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 18

Going ahead to step 3:
The number 18 fits into 45 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 9 after subtracting 36 from 45.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 18

Let's proceed to step 4:
99 divided by 18 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 125.0
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

Going ahead to step 5:
91 divided by 18 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
Subtracting 90 from 91 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 18

Advancing to step 6:
When dividing 16 by 18, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 12550.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 18

Let's proceed to step 7:
If we divide 166 by 18, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 125509.0
The remainder is 4 after subtracting 162 from 166.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 18

On to step 8:
44 divided by 18 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1255092.0
Subtracting 36 from 44 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1255092.4
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
18 goes into 80 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1255092.44
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1255092.44 and a remainder of 0.008.
