We're dividing 103423 by 78 
We want to divide 103423 by 78.

On to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 78

On to step 2:
If we divide 10 by 78, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 78

Advancing to step 3:
78 goes into 103 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 103 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 78

Advancing to step 4:
78 can be fit into 254 3 times, resulting in a remainder of 20.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 234 from 254 leaves us with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 78

Advancing to step 5:
The number 78 fits into 202 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we take 156 away from 202, we end up with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 78

Advancing to step 6:
78 goes into 463 5 times with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 1325.0
If we take 390 away from 463, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
730 divided by 78 is 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 1325.9
If we take 702 away from 730, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1325.93
If we subtract 234 from 280, 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.

Step 9:
78 goes into 460 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 1325.935
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 78 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 1325.9358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 1325.93589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 1325.935897
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.

Moving on to step 13:
78 goes into 340 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1325.9358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
If we divide 280 by 78, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1325.93589743
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.

The quotient of the division is 1325.93589743, and the remainder is 4.6e-08.
