688506 divided by 42 
We want to divide 688506 by 42.

Step 1:
42 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 42

Let's proceed to step 2:
42 can be fit into 68 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 68 leaves us with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 42

On to step 3:
The number 42 fits into 268 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 252 from 268 and we're left with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 42

Moving on to step 4:
42 goes into 165 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 39 after subtracting 126 from 165.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 42

Step 5:
The number 42 fits into 390 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 1639.0
Deduct 378 from 390 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 42

Going ahead to step 6:
126 divided by 42 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 16393.0
Subtracting 126 from 126 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 7:
42 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16393.0
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.

Let's proceed to step 8:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16393.0
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 final result is 16393.0 with a remainder of 0.0.
