We divide 583512 by 42
We want to figure out the number of times 583512 can be divided by 42.

Moving on to step 1:
42 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 42

Going ahead to step 2:
The number 42 fits into 58 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 58 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 42

On to step 3:
42 can be fit into 163 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 126 from 163 and we're left with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 42

On to step 4:
42 goes into 375 8 times with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we subtract 336 from 375, we get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 42

Step 5:
42 goes into 391 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1389.0
If we subtract 378 from 391, we get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 42

Advancing to step 6:
42 goes into 132 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 13893.0
Subtract 126 from 132 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.

On to step 7:
60 divided by 42 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 13893.1
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.

Step 8:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 13893.14
If we take 168 away from 180, we end up 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 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 13893.142
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.

Moving on to step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 13893.1428
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 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 13893.14285
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 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 13893.142857
Subtracting 294 from 300 leaves us 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.
Put 1 as the next digit of the answer. 
Result so far: 13893.1428571
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.

Advancing to step 14:
42 goes into 180 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 13893.14285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 13893.14285714, with a leftover of 1.2e-08.
