68041670 ÷ 839 
Our goal is to divide 68041670 by 839.

Going ahead to step 1:
839 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 839

On to step 2:
839 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 839

On to step 3:
If we divide 680 by 839, we get 0 and a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 680, we get 680.
Fetch the next digit (4) from the dividend, attach it to 680 and continue: 6804 / 839

Advancing to step 4:
839 goes into 6804 8 times with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6712 away from 6804, we end up with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 839

Step 5:
When dividing 921 by 839, we get 1 with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 839 from 921 to get 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 839

Let's proceed to step 6:
If we divide 826 by 839, we get 0 and a remainder of 826.
Write down 0 as next digit of the result. 
Result so far: 810.0
The remainder is 826 after subtracting 0 from 826.
Bring next digit (7) of the dividend behind the 826 and repeat the process: 8267 / 839

On to step 7:
839 can be fit into 8267 9 times, resulting in a remainder of 716.
Put 9 as the next digit of the answer. 
Result so far: 8109.0
Deduct 7551 from 8267 and we're left with 716.
Take the next digit (0) from the dividend and append it to 716, then repeat: 7160 / 839

Advancing to step 8:
839 goes into 7160 8 times with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 81098.0
If we take 6712 away from 7160, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
When dividing 4480 by 839, we get 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 81098.5
If we subtract 4195 from 4480, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
When dividing 2850 by 839, we get 3 with a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 81098.53
Subtracting 2517 from 2850 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 11:
The number 839 fits into 3330 3 times, leaving a remainder of 813.
Put 3 as the next digit of the answer. 
Result so far: 81098.533
Subtracting 2517 from 3330 leaves us with 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Our division results in 81098.533 with a remaining 0.0813.
