Let's divide 837339 by 42
Our goal is to divide 837339 by 42.

On to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 42

Advancing to step 2:
If we divide 83 by 42, we get 1 and a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 83 and we're left with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 42

Going ahead to step 3:
When dividing 417 by 42, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 378 away from 417, we end up with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 42

Going ahead to step 4:
42 goes into 393 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 199.0
If we take 378 away from 393, we end up with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 42

Let's proceed to step 5:
When dividing 153 by 42, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1993.0
The remainder is 27 after subtracting 126 from 153.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 42

On to step 6:
42 can be fit into 279 6 times, resulting in a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 19936.0
Subtracting 252 from 279 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 42, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 19936.6
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 19936.64
If we subtract 168 from 180, we 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.

Moving on to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 19936.642
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 19936.6428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 19936.64285
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.

Step 12:
If we divide 300 by 42, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19936.642857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 19936.6428571
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:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 19936.64285714
Deduct 168 from 180 and we're left 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.

The quotient of the division is 19936.64285714, and the remainder is 1.2e-08.
