72582587 divided by 18 
Let's see how many times 18 fits into 72582587.

Step 1:
18 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

Step 2:
If we divide 72 by 18, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 72 away from 72, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 18

Advancing to step 3:
18 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 18

On to step 4:
18 goes into 58 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 403.0
The remainder is 4 after subtracting 54 from 58.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 18

Let's proceed to step 5:
When dividing 42 by 18, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 4032.0
Subtracting 36 from 42 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 18

Advancing to step 6:
65 divided by 18 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 40323.0
Deduct 54 from 65 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 18

Step 7:
18 goes into 118 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 403236.0
Subtract 108 from 118 to get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

On to step 8:
If we divide 107 by 18, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 4032365.0
Subtract 90 from 107 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
170 divided by 18 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 4032365.9
Subtracting 162 from 170 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.

Advancing to step 10:
80 divided by 18 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4032365.94
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.

Let's proceed to step 11:
If we divide 80 by 18, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4032365.944
Deduct 72 from 80 and we're left 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.

The quotient of the division is 4032365.944, and the remainder is 0.0008.
