We're dividing 838586 by 12 
We want to figure out the number of times 838586 can be divided by 12.

Advancing to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 12

Let's proceed to step 2:
If we divide 83 by 12, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
If we take 72 away from 83, we end up with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Advancing to step 3:
118 divided by 12 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we subtract 108 from 118, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 12

Going ahead to step 4:
If we divide 105 by 12, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 698.0
If we subtract 96 from 105, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

On to step 5:
12 goes into 98 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 6988.0
Subtracting 96 from 98 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 12

Going ahead to step 6:
If we divide 26 by 12, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 69882.0
The remainder is 2 after subtracting 24 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 12 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 69882.1
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 69882.16
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 69882.166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 69882.166 and a remainder of 0.0008.
