We look at the division of 3126486 by 912 
We want to divide 3126486 by 912.

Advancing to step 1:
912 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 912

Let's proceed to step 2:
912 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 912

Going ahead to step 3:
The number 912 fits into 312 0 times, leaving a remainder of 312.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 312 after subtracting 0 from 312.
Bring next digit (6) of the dividend behind the 312 and repeat the process: 3126 / 912

Let's proceed to step 4:
3126 divided by 912 is 3 with a remainder of 390.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2736 from 3126, we get 390.
Fetch the next digit (4) from the dividend, attach it to 390 and continue: 3904 / 912

Moving on to step 5:
912 can be fit into 3904 4 times, resulting in a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 3648 from 3904 leaves us with 256.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 912

Let's proceed to step 6:
2568 divided by 912 is 2 with a remainder of 744.
Write down 2 as next digit of the result. 
Result so far: 342.0
If we subtract 1824 from 2568, we get 744.
Include the next digit (6) from the dividend after 744, then repeat: 7446 / 912

On to step 7:
7446 divided by 912 is 8 with a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 3428.0
The remainder is 150 after subtracting 7296 from 7446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 8:
When dividing 1500 by 912, we get 1 with a remainder of 588.
Record the quotient 1 as the next digit in the result. 
Result so far: 3428.1
If we subtract 912 from 1500, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 9:
5880 divided by 912 is 6 with a remainder of 408.
The next digit of our result is 6. 
Result so far: 3428.16
Subtracting 5472 from 5880 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 10:
When dividing 4080 by 912, we get 4 with a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 3428.164
Deduct 3648 from 4080 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 11:
The number 912 fits into 4320 4 times, leaving a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 3428.1644
The remainder is 672 after subtracting 3648 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The quotient of the division is 3428.1644, and the remainder is 0.00672.
