We're dividing 243985 by 78 
Our goal is to divide 243985 by 78.

On to step 1:
2 divided by 78 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 78

Step 2:
If we divide 24 by 78, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 78

Let's proceed to step 3:
The number 78 fits into 243 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 234 from 243 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 78

Moving on to step 4:
78 goes into 99 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 21 after subtracting 78 from 99.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 78

Going ahead to step 5:
218 divided by 78 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we take 156 away from 218, we end up with 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 78

Let's proceed to step 6:
78 can be fit into 625 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 3128.0
Subtracting 624 from 625 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 78, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3128.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 3128.01
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 3128.012
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3128.0128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3128.01282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
78 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 3128.01282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
400 divided by 78 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3128.0128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
78 goes into 100 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 3128.01282051
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.

The final result is 3128.01282051 with a remainder of 2.2e-08.
