We look at the division of 680342 by 4 
We want to divide 680342 by 4.

On to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Going ahead to step 2:
28 divided by 4 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 28 from 28 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Moving on to step 3:
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: 170.0
If we take 0 away from 0, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

Let's proceed to step 4:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 1700.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Advancing to step 5:
4 goes into 34 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 17008.0
Deduct 32 from 34 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 4

On to step 6:
If we divide 22 by 4, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 170085.0
The remainder is 2 after subtracting 20 from 22.
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 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 170085.5
Subtract 20 from 20 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.

Moving on to step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 170085.5
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:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170085.5
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 170085.5, and the remainder is 0.0.
