18842 ÷ 78 
We're looking to find how many times 78 goes into 18842.

Step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 78

Moving on to step 2:
When dividing 18 by 78, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 78

Step 3:
78 can be fit into 188 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 2.0
If we take 156 away from 188, we end up with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 78

Going ahead to step 4:
The number 78 fits into 324 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 312 from 324 leaves us with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 78

Going ahead to step 5:
If we divide 122 by 78, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 241.0
Subtracting 78 from 122 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 6:
78 goes into 440 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 241.5
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
78 goes into 500 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 241.56
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
78 goes into 320 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 241.564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
78 goes into 80 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 241.5641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 241.5641
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 241.564102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 241.5641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 241.56410256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 241.56410256, with a leftover of 3.2e-08.
