We look at the division of 16448259 by 78 
We want to divide 16448259 by 78.

Moving on to step 1:
78 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 78

Let's proceed to step 2:
If we divide 16 by 78, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 78

Going ahead to step 3:
The number 78 fits into 164 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 156 from 164, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 78

Step 4:
78 goes into 84 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 6 after subtracting 78 from 84.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 78

Going ahead to step 5:
78 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 210.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 78

Moving on to step 6:
If we divide 682 by 78, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 2108.0
Subtracting 624 from 682 leaves us with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 78

Advancing to step 7:
If we divide 585 by 78, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 21087.0
Subtract 546 from 585 to get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 78

Let's proceed to step 8:
The number 78 fits into 399 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 210875.0
If we take 390 away from 399, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
78 goes into 90 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 210875.1
Subtracting 78 from 90 leaves us with 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 10:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 210875.11
If we subtract 78 from 120, we get 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 quotient of the division is 210875.11, and the remainder is 0.042.
