Let's divide 251513 by 18
Let's see how many times 18 fits into 251513.

Let's proceed to step 1:
The number 18 fits into 2 0 times, leaving 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 (5) from the dividend, add it to 2, then carry on: 25 / 18

Going ahead to step 2:
When dividing 25 by 18, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 18 from 25 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 18

Going ahead to step 3:
When dividing 71 by 18, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 54 from 71 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 18

On to step 4:
The number 18 fits into 175 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
The remainder is 13 after subtracting 162 from 175.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 18

On to step 5:
The number 18 fits into 131 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1397.0
Subtract 126 from 131 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 18

Let's proceed to step 6:
If we divide 53 by 18, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 13972.0
Deduct 36 from 53 and we're left with 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 7:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 13972.9
If we subtract 162 from 170, we get 8.
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 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13972.94
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.

Let's proceed to step 9:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13972.944
If we subtract 72 from 80, we get 8.
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 13972.944 and a remainder of 0.0008.
