Let's divide 336986 by 8
Let's see how many times 8 fits into 336986.

Step 1:
8 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 8

Advancing to step 2:
8 goes into 33 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 32 from 33 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 8

Going ahead to step 3:
8 can be fit into 16 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 16 from 16 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 8

On to step 4:
If we divide 9 by 8, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 421.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 8

Going ahead to step 5:
8 can be fit into 18 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4212.0
Subtract 16 from 18 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

On to step 6:
8 goes into 26 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 42123.0
If we take 24 away from 26, we end up with 2.
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 8 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 42123.2
If we take 16 away from 20, we end up 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.

Moving on to step 8:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42123.25
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42123.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42123.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 42123.25 with a remainder of 0.0.
