We look at the division of 804538 by 78 
Let's see how many times 78 fits into 804538.

Advancing to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 78

Going ahead to step 2:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 80 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 78

Moving on to step 3:
78 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 24 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 78

On to step 4:
245 divided by 78 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 103.0
The remainder is 11 after subtracting 234 from 245.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 78

Let's proceed to step 5:
78 goes into 113 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1031.0
Subtracting 78 from 113 leaves us with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 78

Going ahead to step 6:
78 goes into 358 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 10314.0
If we subtract 312 from 358, 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.

On to step 7:
If we divide 460 by 78, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 10314.5
Subtract 390 from 460 to get 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:
When dividing 700 by 78, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 10314.58
Subtract 624 from 700 to get 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:
760 divided by 78 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 10314.589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
When dividing 580 by 78, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 10314.5897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
78 goes into 340 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 10314.58974
If we subtract 312 from 340, we get 28.
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 12:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 10314.589743
Subtract 234 from 280 to 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.

Advancing to step 13:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10314.5897435
If we take 390 away from 460, we end up 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 14:
When dividing 700 by 78, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 10314.58974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 10314.58974358 with a remainder of 7.6e-08.
