We look at the division of 43686684 by 836 
Let's see how many times 836 fits into 43686684.

On to step 1:
836 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 836

On to step 2:
If we divide 43 by 836, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 836

Advancing to step 3:
836 can be fit into 436 0 times, resulting in a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 436 after subtracting 0 from 436.
Include the next digit (8) from the dividend after 436, then repeat: 4368 / 836

Going ahead to step 4:
4368 divided by 836 is 5 with a remainder of 188.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4180 away from 4368, we end up with 188.
Bring next digit (6) of the dividend behind the 188 and repeat the process: 1886 / 836

Let's proceed to step 5:
If we divide 1886 by 836, we get 2 and a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 1672 from 1886, we get 214.
Fetch the next digit (6) from the dividend, attach it to 214 and continue: 2146 / 836

Let's proceed to step 6:
When dividing 2146 by 836, we get 2 with a remainder of 474.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we subtract 1672 from 2146, we get 474.
Fetch the next digit (8) from the dividend, attach it to 474 and continue: 4748 / 836

Going ahead to step 7:
When dividing 4748 by 836, we get 5 with a remainder of 568.
The next digit of our result is 5. 
Result so far: 5225.0
Subtract 4180 from 4748 to get 568.
Fetch the next digit (4) from the dividend, attach it to 568 and continue: 5684 / 836

Advancing to step 8:
836 can be fit into 5684 6 times, resulting in a remainder of 668.
Use 6 as the next digit of our solution. 
Result so far: 52256.0
Subtract 5016 from 5684 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Moving on to step 9:
The number 836 fits into 6680 7 times, leaving a remainder of 828.
Write down 7 as next digit of the result. 
Result so far: 52256.7
The remainder is 828 after subtracting 5852 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Step 10:
If we divide 8280 by 836, we get 9 and a remainder of 756.
Use 9 as the next digit of our solution. 
Result so far: 52256.79
Subtract 7524 from 8280 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Moving on to step 11:
When dividing 7560 by 836, we get 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 52256.799
The remainder is 36 after subtracting 7524 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 52256.799 with a remaining 0.0036.
