We look at the division of 166101 by 39 
We're looking to find how many times 39 goes into 166101.

Going ahead to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 39

Advancing to step 2:
If we divide 16 by 39, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 39

Step 3:
39 can be fit into 166 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 10 after subtracting 156 from 166.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 39

Let's proceed to step 4:
101 divided by 39 is 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 78 from 101 to get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 39

Advancing to step 5:
When dividing 230 by 39, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
The remainder is 35 after subtracting 195 from 230.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 39

Let's proceed to step 6:
The number 39 fits into 351 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 4259.0
Subtract 351 from 351 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.

Step 7:
39 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4259.0
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.

Going ahead to step 8:
39 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4259.0
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 4259.0 with a remaining 0.0.
