853639 divided by 42 
Let's see how many times 42 fits into 853639.

Let's proceed to step 1:
8 divided by 42 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 42

On to step 2:
When dividing 85 by 42, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 85, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 42

Step 3:
42 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 42

On to step 4:
When dividing 136 by 42, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 203.0
If we subtract 126 from 136, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 42

Going ahead to step 5:
When dividing 103 by 42, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 2032.0
Subtracting 84 from 103 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 42

Moving on to step 6:
42 can be fit into 199 4 times, resulting in a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 20324.0
Subtracting 168 from 199 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
42 can be fit into 310 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 20324.7
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 20324.73
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20324.738
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 20324.738
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 20324.73809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 20324.738095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20324.7380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
42 goes into 160 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 20324.73809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 20324.73809523 and a remainder of 3.4e-08.
