Let's divide 12433820 by 306
We're looking to find how many times 306 goes into 12433820.

Let's proceed to step 1:
If we divide 1 by 306, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 306

Let's proceed to step 2:
When dividing 12 by 306, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 306

Let's proceed to step 3:
When dividing 124 by 306, we get 0 with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 306

Moving on to step 4:
The number 306 fits into 1243 4 times, leaving a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 1224 from 1243, we get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 306

Advancing to step 5:
The number 306 fits into 193 0 times, leaving a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 193 to get 193.
Bring next digit (8) of the dividend behind the 193 and repeat the process: 1938 / 306

Advancing to step 6:
If we divide 1938 by 306, we get 6 and a remainder of 102.
The next digit of our result is 6. 
Result so far: 406.0
If we subtract 1836 from 1938, we get 102.
Bring next digit (2) of the dividend behind the 102 and repeat the process: 1022 / 306

Advancing to step 7:
1022 divided by 306 is 3 with a remainder of 104.
The next digit of our result is 3. 
Result so far: 4063.0
Deduct 918 from 1022 and we're left with 104.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 306

Advancing to step 8:
When dividing 1040 by 306, we get 3 with a remainder of 122.
The next digit of our result is 3. 
Result so far: 40633.0
If we subtract 918 from 1040, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 9:
1220 divided by 306 is 3 with a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 40633.3
If we take 918 away from 1220, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
306 goes into 3020 9 times with a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 40633.39
Subtracting 2754 from 3020 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 11:
306 goes into 2660 8 times with a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 40633.398
Subtracting 2448 from 2660 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 12:
306 can be fit into 2120 6 times, resulting in a remainder of 284.
Write down 6 as next digit of the result. 
Result so far: 40633.3986
The remainder is 284 after subtracting 1836 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 13:
306 goes into 2840 9 times with a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 40633.39869
Deduct 2754 from 2840 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 14:
306 goes into 860 2 times with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 40633.398692
Subtracting 612 from 860 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 15:
If we divide 2480 by 306, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 40633.3986928
If we take 2448 away from 2480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
320 divided by 306 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 40633.39869281
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 40633.39869281, with a leftover of 1.4e-08.
