803447 divided by 78 
We're looking to find how many times 78 goes into 803447.

Going ahead to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 78

Moving on to step 2:
If we divide 80 by 78, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 80, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 78

On to step 3:
23 divided by 78 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 23 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 78

On to step 4:
78 goes into 234 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we subtract 234 from 234, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 78

Step 5:
If we divide 4 by 78, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1030.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 78

On to step 6:
If we divide 47 by 78, we get 0 and a remainder of 47.
The next digit of our result is 0. 
Result so far: 10300.0
If we take 0 away from 47, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
78 goes into 470 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 10300.6
The remainder is 2 after subtracting 468 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 78 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10300.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 10300.602
Subtracting 156 from 200 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 10:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 10300.6025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 10300.60256
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.

Advancing to step 12:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10300.602564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
The number 78 fits into 80 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10300.6025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10300.6025641
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.

The final outcome is 10300.6025641, with a leftover of 2e-08.
