We're dividing 12000886 by 18 
Let's see how many times 18 fits into 12000886.

Let's proceed to step 1:
18 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 18

Going ahead to step 2:
When dividing 12 by 18, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 18

Let's proceed to step 3:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 108 from 120 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 18

Going ahead to step 4:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 12 after subtracting 108 from 120.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 18

On to step 5:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 666.0
Deduct 108 from 120 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 18

Let's proceed to step 6:
128 divided by 18 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 6667.0
Subtract 126 from 128 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 18

Advancing to step 7:
18 goes into 28 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 66671.0
Subtract 18 from 28 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 18

Going ahead to step 8:
If we divide 106 by 18, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 666715.0
Subtract 90 from 106 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 666715.8
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 18, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 666715.88
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 666715.88 with a remaining 0.016.
