18342902 ÷ 842 
We're looking to find how many times 842 goes into 18342902.

Going ahead to step 1:
842 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 842

Going ahead to step 2:
If we divide 18 by 842, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 842

Moving on to step 3:
The number 842 fits into 183 0 times, leaving a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Bring next digit (4) of the dividend behind the 183 and repeat the process: 1834 / 842

Advancing to step 4:
1834 divided by 842 is 2 with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1684 from 1834 and we're left with 150.
Include the next digit (2) from the dividend after 150, then repeat: 1502 / 842

On to step 5:
The number 842 fits into 1502 1 times, leaving a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 842 from 1502 to get 660.
Take the next digit (9) from the dividend and append it to 660, then repeat: 6609 / 842

Moving on to step 6:
When dividing 6609 by 842, we get 7 with a remainder of 715.
Put 7 as the next digit of the answer. 
Result so far: 217.0
The remainder is 715 after subtracting 5894 from 6609.
Include the next digit (0) from the dividend after 715, then repeat: 7150 / 842

Advancing to step 7:
If we divide 7150 by 842, we get 8 and a remainder of 414.
Use 8 as the next digit of our solution. 
Result so far: 2178.0
Subtracting 6736 from 7150 leaves us with 414.
Take the next digit (2) from the dividend and append it to 414, then repeat: 4142 / 842

Going ahead to step 8:
When dividing 4142 by 842, we get 4 with a remainder of 774.
The next digit of our result is 4. 
Result so far: 21784.0
The remainder is 774 after subtracting 3368 from 4142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Step 9:
When dividing 7740 by 842, we get 9 with a remainder of 162.
Record the quotient 9 as the next digit in the result. 
Result so far: 21784.9
Subtracting 7578 from 7740 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
If we divide 1620 by 842, we get 1 and a remainder of 778.
Use 1 as the next digit of our solution. 
Result so far: 21784.91
If we take 842 away from 1620, we end up with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Step 11:
If we divide 7780 by 842, we get 9 and a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 21784.919
If we take 7578 away from 7780, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 12:
If we divide 2020 by 842, we get 2 and a remainder of 336.
The next digit of our result is 2. 
Result so far: 21784.9192
Subtracting 1684 from 2020 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
When dividing 3360 by 842, we get 3 with a remainder of 834.
Record the quotient 3 as the next digit in the result. 
Result so far: 21784.91923
Subtracting 2526 from 3360 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 14:
When dividing 8340 by 842, we get 9 with a remainder of 762.
Record the quotient 9 as the next digit in the result. 
Result so far: 21784.919239
Subtracting 7578 from 8340 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Moving on to step 15:
7620 divided by 842 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 21784.9192399
Subtracting 7578 from 7620 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 21784.9192399, with a leftover of 4.2e-07.
