19138 divided by 78 
Let's see how many times 78 fits into 19138.

Moving on to step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 78

Moving on to step 2:
78 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 78

Advancing to step 3:
78 goes into 191 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 35 after subtracting 156 from 191.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 78

Going ahead to step 4:
The number 78 fits into 353 4 times, leaving a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 312 from 353 and we're left with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 78

Advancing to step 5:
If we divide 418 by 78, we get 5 and a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 245.0
The remainder is 28 after subtracting 390 from 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 6:
If we divide 280 by 78, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 245.3
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.35
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
78 goes into 700 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 245.358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
78 goes into 760 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 245.3589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 78 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 245.35897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 245.358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
If we divide 280 by 78, we get 3 and a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 245.3589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
If we divide 460 by 78, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 245.35897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 245.35897435, with a leftover of 7e-08.
