12905772 ÷ 386 
We want to figure out the number of times 12905772 can be divided by 386.

Step 1:
386 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 386

On to step 2:
If we divide 12 by 386, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 386

Moving on to step 3:
386 can be fit into 129 0 times, resulting in a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Fetch the next digit (0) from the dividend, attach it to 129 and continue: 1290 / 386

Going ahead to step 4:
If we divide 1290 by 386, we get 3 and a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1158 from 1290 to get 132.
Take the next digit (5) from the dividend and append it to 132, then repeat: 1325 / 386

Let's proceed to step 5:
386 goes into 1325 3 times with a remainder of 167.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 1158 away from 1325, we end up with 167.
Include the next digit (7) from the dividend after 167, then repeat: 1677 / 386

Advancing to step 6:
1677 divided by 386 is 4 with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 334.0
The remainder is 133 after subtracting 1544 from 1677.
Grab the next digit (7) from the dividend, add it to 133, then carry on: 1337 / 386

Step 7:
If we divide 1337 by 386, we get 3 and a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 3343.0
Subtracting 1158 from 1337 leaves us with 179.
Take the next digit (2) from the dividend and append it to 179, then repeat: 1792 / 386

Moving on to step 8:
386 can be fit into 1792 4 times, resulting in a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 33434.0
Subtracting 1544 from 1792 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.

Advancing to step 9:
386 goes into 2480 6 times with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 33434.6
The remainder is 164 after subtracting 2316 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
386 can be fit into 1640 4 times, resulting in a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 33434.64
Subtracting 1544 from 1640 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.

Let's proceed to step 11:
960 divided by 386 is 2 with a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 33434.642
The remainder is 188 after subtracting 772 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
The number 386 fits into 1880 4 times, leaving a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 33434.6424
Subtracting 1544 from 1880 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
386 goes into 3360 8 times with a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 33434.64248
If we take 3088 away from 3360, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 14:
When dividing 2720 by 386, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 33434.642487
The remainder is 18 after subtracting 2702 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
386 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 33434.642487
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
386 goes into 1800 4 times with a remainder of 256.
The next digit of our result is 4. 
Result so far: 33434.64248704
The remainder is 256 after subtracting 1544 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 33434.64248704, and the remainder is 2.56e-07.
