We're dividing 251093 by 18 
Let's see how many times 18 fits into 251093.

Step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 18

Advancing to step 2:
25 divided by 18 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 18 from 25.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 18

Moving on to step 3:
The number 18 fits into 71 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 54 away from 71, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 18

Going ahead to step 4:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we subtract 162 from 170, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 18

Advancing to step 5:
The number 18 fits into 89 4 times, leaving a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 1394.0
Subtract 72 from 89 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 18

Step 6:
18 goes into 173 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 13949.0
Deduct 162 from 173 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 18 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 13949.6
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 18, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 13949.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
18 goes into 20 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 13949.611
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 13949.611 with a remaining 0.0002.
