We divide 12531864 by 306
Our goal is to divide 12531864 by 306.

Moving on to step 1:
306 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 306

On to step 2:
The number 306 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 306

Let's proceed to step 3:
306 goes into 125 0 times with a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Fetch the next digit (3) from the dividend, attach it to 125 and continue: 1253 / 306

Step 4:
306 can be fit into 1253 4 times, resulting in a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1224 from 1253 to get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 306

Advancing to step 5:
When dividing 291 by 306, we get 0 with a remainder of 291.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 291, we end up with 291.
Grab the next digit (8) from the dividend, add it to 291, then carry on: 2918 / 306

Let's proceed to step 6:
When dividing 2918 by 306, we get 9 with a remainder of 164.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Deduct 2754 from 2918 and we're left with 164.
Grab the next digit (6) from the dividend, add it to 164, then carry on: 1646 / 306

Let's proceed to step 7:
If we divide 1646 by 306, we get 5 and a remainder of 116.
The next digit of our result is 5. 
Result so far: 4095.0
Subtract 1530 from 1646 to get 116.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 306

Moving on to step 8:
The number 306 fits into 1164 3 times, leaving a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 40953.0
The remainder is 246 after subtracting 918 from 1164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 9:
The number 306 fits into 2460 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 40953.8
If we take 2448 away from 2460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
306 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 40953.8
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
1200 divided by 306 is 3 with a remainder of 282.
The next digit of our result is 3. 
Result so far: 40953.803
If we subtract 918 from 1200, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 12:
When dividing 2820 by 306, we get 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 40953.8039
If we take 2754 away from 2820, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
The number 306 fits into 660 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 40953.80392
If we take 612 away from 660, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
306 can be fit into 480 1 times, resulting in a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 40953.803921
The remainder is 174 after subtracting 306 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 15:
If we divide 1740 by 306, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 40953.8039215
Subtract 1530 from 1740 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 16:
2100 divided by 306 is 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 40953.80392156
Subtract 1836 from 2100 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

In conclusion, the division gives 40953.80392156 with a balance of 2.64e-07.
