We look at the division of 138166 by 10 
Let's see how many times 10 fits into 138166.

Moving on to step 1:
If we divide 1 by 10, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 10

On to step 2:
10 can be fit into 13 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 10 from 13, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 10

Step 3:
If we divide 38 by 10, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 30 from 38 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 10

On to step 4:
10 goes into 81 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 138.0
If we subtract 80 from 81, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 10

Moving on to step 5:
When dividing 16 by 10, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1381.0
The remainder is 6 after subtracting 10 from 16.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 10

On to step 6:
The number 10 fits into 66 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 13816.0
The remainder is 6 after subtracting 60 from 66.
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 7:
If we divide 60 by 10, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 13816.6
Deduct 60 from 60 and we're left 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.

Let's proceed to step 8:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13816.6
If we subtract 0 from 0, we 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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13816.6
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.

Our division results in 13816.6 with a remaining 0.0.
