67830991 ÷ 936 
Our goal is to divide 67830991 by 936.

On to step 1:
When dividing 6 by 936, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 936

Advancing to step 2:
When dividing 67 by 936, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 936

Going ahead to step 3:
936 goes into 678 0 times with a remainder of 678.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 678, we end up with 678.
Include the next digit (3) from the dividend after 678, then repeat: 6783 / 936

Going ahead to step 4:
6783 divided by 936 is 7 with a remainder of 231.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6552 from 6783, we get 231.
Fetch the next digit (0) from the dividend, attach it to 231 and continue: 2310 / 936

Moving on to step 5:
936 goes into 2310 2 times with a remainder of 438.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 1872 from 2310, we get 438.
Fetch the next digit (9) from the dividend, attach it to 438 and continue: 4389 / 936

On to step 6:
4389 divided by 936 is 4 with a remainder of 645.
Put 4 as the next digit of the answer. 
Result so far: 724.0
Subtract 3744 from 4389 to get 645.
Include the next digit (9) from the dividend after 645, then repeat: 6459 / 936

Going ahead to step 7:
936 can be fit into 6459 6 times, resulting in a remainder of 843.
Use 6 as the next digit of our solution. 
Result so far: 7246.0
If we take 5616 away from 6459, we end up with 843.
Append the next digit (1) from the dividend to 843 and continue with: 8431 / 936

Advancing to step 8:
936 goes into 8431 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 72469.0
If we subtract 8424 from 8431, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 936, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 72469.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
936 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 72469.0
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 72469.0 with a remaining 0.7.
