578463 divided by 42 
We want to divide 578463 by 42.

Step 1:
If we divide 5 by 42, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 42

On to step 2:
42 goes into 57 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 57 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 42

Moving on to step 3:
42 can be fit into 158 3 times, resulting in a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 126 from 158 and we're left with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 42

Going ahead to step 4:
The number 42 fits into 324 7 times, leaving a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 137.0
If we take 294 away from 324, we end up with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 42

Advancing to step 5:
306 divided by 42 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 1377.0
Subtract 294 from 306 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 42

Going ahead to step 6:
The number 42 fits into 123 2 times, leaving a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 13772.0
If we take 84 away from 123, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
42 can be fit into 390 9 times, resulting in a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 13772.9
Deduct 378 from 390 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.

Let's proceed to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 13772.92
If we take 84 away from 120, we end up 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.

On to step 9:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 13772.928
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 42, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 13772.9285
Subtracting 210 from 240 leaves us 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 11:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 13772.92857
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.

On to step 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 13772.928571
Deduct 42 from 60 and we're left 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 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 13772.9285714
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 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 13772.92857142
Deduct 84 from 120 and we're left 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.

The final outcome is 13772.92857142, with a leftover of 3.6e-08.
