30613688 ÷ 836 
We want to figure out the number of times 30613688 can be divided by 836.

On to step 1:
3 divided by 836 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 836

Step 2:
The number 836 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 836

Let's proceed to step 3:
836 goes into 306 0 times with a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Append the next digit (1) from the dividend to 306 and continue with: 3061 / 836

Step 4:
If we divide 3061 by 836, we get 3 and a remainder of 553.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2508 from 3061 and we're left with 553.
Fetch the next digit (3) from the dividend, attach it to 553 and continue: 5533 / 836

On to step 5:
The number 836 fits into 5533 6 times, leaving a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 5016 from 5533 leaves us with 517.
Include the next digit (6) from the dividend after 517, then repeat: 5176 / 836

Advancing to step 6:
If we divide 5176 by 836, we get 6 and a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 366.0
Deduct 5016 from 5176 and we're left with 160.
Bring next digit (8) of the dividend behind the 160 and repeat the process: 1608 / 836

Moving on to step 7:
836 can be fit into 1608 1 times, resulting in a remainder of 772.
The next digit of our result is 1. 
Result so far: 3661.0
Subtract 836 from 1608 to get 772.
Include the next digit (8) from the dividend after 772, then repeat: 7728 / 836

Let's proceed to step 8:
If we divide 7728 by 836, we get 9 and a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 36619.0
If we take 7524 away from 7728, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 9:
When dividing 2040 by 836, we get 2 with a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 36619.2
Subtracting 1672 from 2040 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
836 goes into 3680 4 times with a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 36619.24
Deduct 3344 from 3680 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 11:
3360 divided by 836 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 36619.244
If we take 3344 away from 3360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 36619.244, and the remainder is 0.0016.
