We look at the division of 186 by 10 
We want to divide 186 by 10.

Going ahead to step 1:
10 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 10

Going ahead to step 2:
When dividing 18 by 10, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 10 from 18 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 10

On to step 3:
If we divide 86 by 10, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 80 from 86, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 4:
60 divided by 10 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 18.6
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 5:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 18.6, and the remainder is 0.0.
