581949 ÷ 42 
We want to divide 581949 by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 42

Going ahead to step 2:
42 can be fit into 58 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 58 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 42

Let's proceed to step 3:
42 can be fit into 161 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 126 from 161 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 42

Moving on to step 4:
359 divided by 42 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 23 after subtracting 336 from 359.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 42

Step 5:
When dividing 234 by 42, we get 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 1385.0
Deduct 210 from 234 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 42

Moving on to step 6:
The number 42 fits into 249 5 times, leaving a remainder of 39.
The next digit of our result is 5. 
Result so far: 13855.0
If we take 210 away from 249, 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.

Advancing to step 7:
42 can be fit into 390 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 13855.9
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 13855.92
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.

Moving on to step 9:
42 goes into 360 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 13855.928
If we subtract 336 from 360, we 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.

Going ahead to step 10:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13855.9285
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.

On to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 13855.92857
If we subtract 294 from 300, we 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.

Moving on to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 13855.928571
Subtracting 42 from 60 leaves us 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 13:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 13855.9285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 13855.92857142
The remainder is 36 after subtracting 84 from 120.
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 13855.92857142, with a leftover of 3.6e-08.
