303943 divided by 78 
We want to divide 303943 by 78.

Going ahead to step 1:
3 divided by 78 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 78

Let's proceed to step 2:
78 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 78

Advancing to step 3:
303 divided by 78 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 234 away from 303, we end up with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 78

Advancing to step 4:
78 goes into 699 8 times with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 624 from 699 to get 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 78

Let's proceed to step 5:
If we divide 754 by 78, we get 9 and a remainder of 52.
The next digit of our result is 9. 
Result so far: 389.0
Deduct 702 from 754 and we're left with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 78

Let's proceed to step 6:
When dividing 523 by 78, we get 6 with a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 3896.0
Deduct 468 from 523 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
If we divide 550 by 78, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3896.7
Deduct 546 from 550 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 78 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 3896.7
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 78 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3896.705
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 3896.7051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 78, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 3896.70512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3896.705128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3896.7051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3896.7051282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 3896.7051282 with a remaining 4e-08.
