583929 divided by 42 
Let's see how many times 42 fits into 583929.

Step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 42

Going ahead to step 2:
If we divide 58 by 42, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 58 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 42

Advancing to step 3:
If we divide 163 by 42, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 37 after subtracting 126 from 163.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 42

Going ahead to step 4:
379 divided by 42 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 378 from 379, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 42

Moving on to step 5:
42 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 1390.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 42

On to step 6:
The number 42 fits into 129 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13903.0
Deduct 126 from 129 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 42, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 13903.0
Deduct 0 from 30 and we're left 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 8:
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: 13903.07
Subtract 294 from 300 to 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.

Step 9:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 13903.071
If we subtract 42 from 60, we 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.

Let's proceed to step 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 13903.0714
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.

Moving on to step 11:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 13903.07142
Subtracting 84 from 120 leaves us 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 12:
42 goes into 360 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 13903.071428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 13903.0714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 13903.07142857
Subtract 294 from 300 to 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.

After the division, we end up with 13903.07142857 and a remainder of 6e-09.
