Let's divide 939886 by 12
We want to divide 939886 by 12.

Moving on to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 12

Going ahead to step 2:
12 can be fit into 93 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 84 from 93 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 12

Let's proceed to step 3:
If we divide 99 by 12, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 96 away from 99, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Let's proceed to step 4:
If we divide 38 by 12, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 783.0
Subtract 36 from 38 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

On to step 5:
When dividing 28 by 12, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7832.0
If we take 24 away from 28, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 12

Moving on to step 6:
12 can be fit into 46 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 78323.0
If we take 36 away from 46, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 12 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 78323.8
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 78323.83
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 78323.833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 78323.833, and the remainder is 0.0004.
