838704 ÷ 42 
Let's see how many times 42 fits into 838704.

Moving on to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 42

Advancing to step 2:
42 goes into 83 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 83 to get 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 42

Step 3:
If we divide 418 by 42, we get 9 and a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 378 from 418 leaves us with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 42

Going ahead to step 4:
If we divide 407 by 42, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
The remainder is 29 after subtracting 378 from 407.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 42

On to step 5:
42 can be fit into 290 6 times, resulting in a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 1996.0
Subtract 252 from 290 to get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 42

Advancing to step 6:
The number 42 fits into 384 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 19969.0
If we subtract 378 from 384, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19969.1
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
When dividing 180 by 42, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 19969.14
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 19969.142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 19969.1428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 19969.14285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 19969.142857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 19969.1428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
180 divided by 42 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19969.14285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 19969.14285714 and a remainder of 1.2e-08.
