78281212 divided by 331 
Let's see how many times 331 fits into 78281212.

Let's proceed to step 1:
The number 331 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 331

Going ahead to step 2:
78 divided by 331 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 331

Let's proceed to step 3:
782 divided by 331 is 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 662 from 782, we get 120.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 331

Step 4:
1208 divided by 331 is 3 with a remainder of 215.
The next digit of our result is 3. 
Result so far: 23.0
If we take 993 away from 1208, we end up with 215.
Fetch the next digit (1) from the dividend, attach it to 215 and continue: 2151 / 331

Moving on to step 5:
The number 331 fits into 2151 6 times, leaving a remainder of 165.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Subtract 1986 from 2151 to get 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 331

Going ahead to step 6:
When dividing 1652 by 331, we get 4 with a remainder of 328.
The next digit of our result is 4. 
Result so far: 2364.0
If we subtract 1324 from 1652, we get 328.
Include the next digit (1) from the dividend after 328, then repeat: 3281 / 331

Let's proceed to step 7:
The number 331 fits into 3281 9 times, leaving a remainder of 302.
The next digit of our result is 9. 
Result so far: 23649.0
If we subtract 2979 from 3281, we get 302.
Grab the next digit (2) from the dividend, add it to 302, then carry on: 3022 / 331

Going ahead to step 8:
331 goes into 3022 9 times with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 236499.0
If we subtract 2979 from 3022, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
430 divided by 331 is 1 with a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 236499.1
Subtracting 331 from 430 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
When dividing 990 by 331, we get 2 with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 236499.12
If we take 662 away from 990, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 11:
If we divide 3280 by 331, we get 9 and a remainder of 301.
Put 9 as the next digit of the answer. 
Result so far: 236499.129
If we subtract 2979 from 3280, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 12:
331 can be fit into 3010 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 236499.1299
If we subtract 2979 from 3010, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 236499.1299, with a leftover of 0.00031.
