We look at the division of 12936145 by 386 
We want to divide 12936145 by 386.

Advancing to step 1:
1 divided by 386 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
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 / 386

Step 2:
386 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 386

Step 3:
129 divided by 386 is 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 386

Step 4:
386 goes into 1293 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 135 after subtracting 1158 from 1293.
Append the next digit (6) from the dividend to 135 and continue with: 1356 / 386

On to step 5:
386 can be fit into 1356 3 times, resulting in a remainder of 198.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 1158 from 1356 to get 198.
Fetch the next digit (1) from the dividend, attach it to 198 and continue: 1981 / 386

Let's proceed to step 6:
If we divide 1981 by 386, we get 5 and a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
Subtract 1930 from 1981 to get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 386

Going ahead to step 7:
514 divided by 386 is 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 3351.0
Subtracting 386 from 514 leaves us with 128.
Take the next digit (5) from the dividend and append it to 128, then repeat: 1285 / 386

Going ahead to step 8:
When dividing 1285 by 386, we get 3 with a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 33513.0
The remainder is 127 after subtracting 1158 from 1285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 9:
When dividing 1270 by 386, we get 3 with a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 33513.3
Subtract 1158 from 1270 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
The number 386 fits into 1120 2 times, leaving a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 33513.32
The remainder is 348 after subtracting 772 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 11:
If we divide 3480 by 386, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 33513.329
Subtracting 3474 from 3480 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
When dividing 60 by 386, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 33513.329
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
386 can be fit into 600 1 times, resulting in a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 33513.32901
If we take 386 away from 600, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 14:
386 goes into 2140 5 times with a remainder of 210.
The next digit of our result is 5. 
Result so far: 33513.329015
Subtract 1930 from 2140 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 15:
The number 386 fits into 2100 5 times, leaving a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 33513.3290155
If we take 1930 away from 2100, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 33513.3290155 with a balance of 1.7e-06.
