12306942 ÷ 771 
Let's see how many times 771 fits into 12306942.

Let's proceed to step 1:
The number 771 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 771

Let's proceed to step 2:
771 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 771

Let's proceed to step 3:
If we divide 123 by 771, we get 0 and a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 771

Advancing to step 4:
When dividing 1230 by 771, we get 1 with a remainder of 459.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 771 from 1230 to get 459.
Take the next digit (6) from the dividend and append it to 459, then repeat: 4596 / 771

Step 5:
When dividing 4596 by 771, we get 5 with a remainder of 741.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 3855 from 4596 and we're left with 741.
Take the next digit (9) from the dividend and append it to 741, then repeat: 7419 / 771

Going ahead to step 6:
7419 divided by 771 is 9 with a remainder of 480.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 480 after subtracting 6939 from 7419.
Bring next digit (4) of the dividend behind the 480 and repeat the process: 4804 / 771

On to step 7:
If we divide 4804 by 771, we get 6 and a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 1596.0
Subtract 4626 from 4804 to get 178.
Append the next digit (2) from the dividend to 178 and continue with: 1782 / 771

Advancing to step 8:
1782 divided by 771 is 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 15962.0
Subtract 1542 from 1782 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 9:
The number 771 fits into 2400 3 times, leaving a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 15962.3
If we take 2313 away from 2400, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
870 divided by 771 is 1 with a remainder of 99.
The next digit of our result is 1. 
Result so far: 15962.31
If we subtract 771 from 870, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 11:
If we divide 990 by 771, we get 1 and a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 15962.311
If we subtract 771 from 990, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

After the division, we end up with 15962.311 and a remainder of 0.0219.
