2874904 ÷ 42 
We want to divide 2874904 by 42.

Moving on to step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 42

Going ahead to step 2:
42 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 42

Step 3:
If we divide 287 by 42, we get 6 and a remainder of 35.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 35 after subtracting 252 from 287.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 42

On to step 4:
The number 42 fits into 354 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 336 from 354 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 42

Step 5:
42 can be fit into 189 4 times, resulting in a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 684.0
Subtract 168 from 189 to get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 42

Going ahead to step 6:
The number 42 fits into 210 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6845.0
Deduct 210 from 210 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 42

Advancing to step 7:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 68450.0
If we subtract 0 from 4, 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.

On to step 8:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 68450.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 68450.09
Subtracting 378 from 400 leaves us 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.

Moving on to step 10:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 68450.095
Subtracting 210 from 220 leaves us 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.

Moving on to step 11:
100 divided by 42 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 68450.0952
If we take 84 away from 100, we end up 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.

On to step 12:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 68450.09523
Subtract 126 from 160 to 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.

Moving on to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 68450.095238
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.

On to step 14:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 68450.095238
If we subtract 0 from 40, we get 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 15:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 68450.09523809
The remainder is 22 after subtracting 378 from 400.
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 outcome is 68450.09523809, with a leftover of 2.2e-08.
