346580 divided by 42 
We want to divide 346580 by 42.

Let's proceed to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 42

Going ahead to step 2:
The number 42 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 42

Going ahead to step 3:
The number 42 fits into 346 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 8.0
If we take 336 away from 346, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 42

Going ahead to step 4:
The number 42 fits into 105 2 times, leaving a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 84 from 105, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 42

Step 5:
When dividing 218 by 42, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
Deduct 210 from 218 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 42

On to step 6:
42 goes into 80 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 8251.0
Subtracting 42 from 80 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.

Step 7:
If we divide 380 by 42, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 8251.9
Deduct 378 from 380 and we're left 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 8:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8251.9
If we take 0 away from 20, we end up 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.

Let's proceed to step 9:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8251.904
Subtract 168 from 200 to get 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:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 8251.9047
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.

Going ahead to step 11:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 8251.90476
Deduct 252 from 260 and we're left 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.

Step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 8251.904761
If we take 42 away from 80, we end up 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.

Moving on 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: 8251.9047619
If we subtract 378 from 380, 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.

Let's proceed to step 14:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8251.9047619
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.

After the division, we end up with 8251.9047619 and a remainder of 2e-08.
