We divide 12348105 by 306
Our goal is to divide 12348105 by 306.

Going ahead to step 1:
The number 306 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 306

Going ahead to step 2:
The number 306 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 306

Going ahead to step 3:
The number 306 fits into 123 0 times, leaving a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Fetch the next digit (4) from the dividend, attach it to 123 and continue: 1234 / 306

Advancing to step 4:
The number 306 fits into 1234 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1224 from 1234 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 306

On to step 5:
306 goes into 108 0 times with a remainder of 108.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 108 leaves us with 108.
Take the next digit (1) from the dividend and append it to 108, then repeat: 1081 / 306

Step 6:
1081 divided by 306 is 3 with a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Subtracting 918 from 1081 leaves us with 163.
Fetch the next digit (0) from the dividend, attach it to 163 and continue: 1630 / 306

Let's proceed to step 7:
306 goes into 1630 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 4035.0
The remainder is 100 after subtracting 1530 from 1630.
Include the next digit (5) from the dividend after 100, then repeat: 1005 / 306

Going ahead to step 8:
When dividing 1005 by 306, we get 3 with a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 40353.0
Subtracting 918 from 1005 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
If we divide 870 by 306, we get 2 and a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 40353.2
Deduct 612 from 870 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 10:
306 goes into 2580 8 times with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 40353.28
If we take 2448 away from 2580, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
1320 divided by 306 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 40353.284
Subtracting 1224 from 1320 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
306 goes into 960 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 40353.2843
If we take 918 away from 960, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
If we divide 420 by 306, we get 1 and a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 40353.28431
Deduct 306 from 420 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 14:
306 can be fit into 1140 3 times, resulting in a remainder of 222.
The next digit of our result is 3. 
Result so far: 40353.284313
If we subtract 918 from 1140, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 15:
When dividing 2220 by 306, we get 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 40353.2843137
Subtract 2142 from 2220 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 16:
306 goes into 780 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 40353.28431372
Subtract 612 from 780 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 40353.28431372, with a leftover of 1.68e-07.
