583804 divided by 42 
Let's see how many times 42 fits into 583804.

Step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 42

On to step 2:
The number 42 fits into 58 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 16 after subtracting 42 from 58.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 42

Moving on to step 3:
The number 42 fits into 163 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 126 from 163, we get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 42

Step 4:
The number 42 fits into 378 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 378 from 378 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 42

Let's proceed to step 5:
When dividing 0 by 42, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1390.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 42

Moving on to step 6:
When dividing 4 by 42, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 13900.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13900.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 13900.09
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13900.095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 42, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 13900.0952
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.

Let's proceed to step 11:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13900.09523
If we subtract 126 from 160, we get 34.
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 12:
42 goes into 340 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 13900.095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13900.095238
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 13900.09523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 13900.09523809 with a remainder of 2.2e-08.
