Let's divide 603843 by 78
We want to figure out the number of times 603843 can be divided by 78.

Moving on to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 78

Let's proceed to step 2:
When dividing 60 by 78, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 78

Moving on to step 3:
603 divided by 78 is 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 546 from 603 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 78

Going ahead to step 4:
78 can be fit into 578 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 546 from 578 leaves us with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 78

Advancing to step 5:
324 divided by 78 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 774.0
If we take 312 away from 324, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 78

Going ahead to step 6:
123 divided by 78 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 7741.0
Subtract 78 from 123 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
450 divided by 78 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 7741.5
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 7741.57
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
If we divide 540 by 78, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 7741.576
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 7741.5769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
When dividing 180 by 78, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 7741.57692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 7741.576923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7741.576923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7741.57692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 7741.57692307, with a leftover of 5.4e-08.
