342506 divided by 42 
Let's see how many times 42 fits into 342506.

On to step 1:
3 divided by 42 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 42

Step 2:
42 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 42

Going ahead to step 3:
When dividing 342 by 42, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 336 from 342 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 42

Moving on to step 4:
42 goes into 65 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 42 from 65 to get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 42

Moving on to step 5:
42 can be fit into 230 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 815.0
Subtracting 210 from 230 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 42

Advancing to step 6:
42 goes into 206 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 8154.0
Subtracting 168 from 206 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
When dividing 380 by 42, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8154.9
The remainder is 2 after subtracting 378 from 380.
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 8:
42 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8154.9
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8154.904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 8154.9047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8154.90476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 8154.904761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
380 divided by 42 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8154.9047619
If we take 378 away from 380, we end up 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 14:
42 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8154.9047619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 8154.9047619 with a remaining 2e-08.
