We look at the division of 166818 by 4 
We're looking to find how many times 4 goes into 166818.

On to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 4

Advancing to step 2:
16 divided by 4 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 16 from 16 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Moving 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
Subtracting 4 from 6 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 4

Advancing to step 4:
4 can be fit into 28 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 417.0
If we subtract 28 from 28, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Advancing to step 5:
1 divided by 4 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 4170.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

Going ahead to step 6:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 41704.0
Subtracting 16 from 18 leaves us 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.

Let's proceed to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41704.5
If we subtract 20 from 20, 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 8:
4 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: 41704.5
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.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41704.5
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.

The quotient of the division is 41704.5, and the remainder is 0.0.
