166931 ÷ 4 
Our goal is to divide 166931 by 4.

Let's proceed to step 1:
4 can be fit into 1 0 times, resulting in 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.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

Going ahead to step 2:
4 goes into 16 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 16 from 16 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

On to step 3:
4 can be fit into 6 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 4 away from 6, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 4

Advancing to step 4:
The number 4 fits into 29 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 417.0
Subtracting 28 from 29 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 4

Moving on to step 5:
4 goes into 13 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 4173.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Let's proceed to step 6:
The number 4 fits into 11 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 41732.0
The remainder is 3 after subtracting 8 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 41732.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 41732.75
The remainder is 0 after subtracting 20 from 20.
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 9:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41732.75
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.

Step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41732.75
The remainder is 0 after subtracting 0 from 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 41732.75, and the remainder is 0.0.
