660342 ÷ 4 
Our goal is to divide 660342 by 4.

Going ahead to step 1:
4 goes into 6 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 4 away from 6, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Moving on to step 2:
4 can be fit into 26 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 24 from 26 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 4

Let's proceed to step 3:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
The remainder is 0 after subtracting 20 from 20.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Advancing to step 4:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 1650.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Advancing to step 5:
34 divided by 4 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 16508.0
Subtract 32 from 34 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

On to step 6:
4 can be fit into 22 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 165085.0
If we subtract 20 from 22, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 165085.5
Subtracting 20 from 20 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.

On to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 165085.5
Subtracting 0 from 0 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.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 165085.5
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.

Our division results in 165085.5 with a remaining 0.0.
