We're dividing 78154331 by 318 
Let's see how many times 318 fits into 78154331.

Step 1:
The number 318 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 318

Step 2:
The number 318 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 318

Let's proceed to step 3:
If we divide 781 by 318, we get 2 and a remainder of 145.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 636 from 781 to get 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 318

Going ahead to step 4:
318 goes into 1455 4 times with a remainder of 183.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 1272 from 1455, we get 183.
Take the next digit (4) from the dividend and append it to 183, then repeat: 1834 / 318

On to step 5:
318 goes into 1834 5 times with a remainder of 244.
Put 5 as the next digit of the answer. 
Result so far: 245.0
Subtract 1590 from 1834 to get 244.
Bring next digit (3) of the dividend behind the 244 and repeat the process: 2443 / 318

On to step 6:
318 can be fit into 2443 7 times, resulting in a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 2457.0
If we take 2226 away from 2443, we end up with 217.
Take the next digit (3) from the dividend and append it to 217, then repeat: 2173 / 318

Going ahead to step 7:
The number 318 fits into 2173 6 times, leaving a remainder of 265.
Put 6 as the next digit of the answer. 
Result so far: 24576.0
Deduct 1908 from 2173 and we're left with 265.
Append the next digit (1) from the dividend to 265 and continue with: 2651 / 318

Let's proceed to step 8:
When dividing 2651 by 318, we get 8 with a remainder of 107.
Put 8 as the next digit of the answer. 
Result so far: 245768.0
Subtracting 2544 from 2651 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 9:
318 goes into 1070 3 times with a remainder of 116.
The next digit of our result is 3. 
Result so far: 245768.3
Subtracting 954 from 1070 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
318 goes into 1160 3 times with a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 245768.33
If we subtract 954 from 1160, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

After the division, we end up with 245768.33 and a remainder of 0.206.
