We look at the division of 166187 by 10 
Let's see how many times 10 fits into 166187.

Moving on to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 10

Advancing to step 2:
10 can be fit into 16 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 10 from 16, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 10

Going ahead to step 3:
10 goes into 66 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 60 from 66, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 10

Going ahead to step 4:
The number 10 fits into 61 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
If we take 60 away from 61, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 10

Advancing to step 5:
18 divided by 10 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1661.0
Subtracting 10 from 18 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 10

Moving on to step 6:
When dividing 87 by 10, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 16618.0
Subtracting 80 from 87 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
10 goes into 70 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 16618.7
Subtracting 70 from 70 leaves us 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.

Moving on to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16618.7
Deduct 0 from 0 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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16618.7
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.

After the division, we end up with 16618.7 and a remainder of 0.0.
