166635 ÷ 10 
We want to figure out the number of times 166635 can be divided by 10.

Step 1:
The number 10 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 10

On to step 2:
10 goes into 16 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 10 from 16 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 10

On to step 3:
The number 10 fits into 66 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 60 from 66 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 10

Step 4:
10 goes into 66 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Subtract 60 from 66 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 10

On to step 5:
When dividing 63 by 10, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1666.0
If we take 60 away from 63, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 10

Moving on to step 6:
If we divide 35 by 10, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 16663.0
If we subtract 30 from 35, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
10 can be fit into 50 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16663.5
The remainder is 0 after subtracting 50 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16663.5
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:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16663.5
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.

Our division results in 16663.5 with a remaining 0.0.
