63965210 ÷ 834 
We want to figure out the number of times 63965210 can be divided by 834.

Going ahead to step 1:
834 goes into 6 0 times 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 (3) of the dividend behind the 6 and repeat the process: 63 / 834

Advancing to step 2:
The number 834 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 834

Step 3:
When dividing 639 by 834, we get 0 with a remainder of 639.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 639 and we're left with 639.
Grab the next digit (6) from the dividend, add it to 639, then carry on: 6396 / 834

Step 4:
834 goes into 6396 7 times with a remainder of 558.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5838 away from 6396, we end up with 558.
Bring next digit (5) of the dividend behind the 558 and repeat the process: 5585 / 834

Advancing to step 5:
When dividing 5585 by 834, we get 6 with a remainder of 581.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtracting 5004 from 5585 leaves us with 581.
Bring next digit (2) of the dividend behind the 581 and repeat the process: 5812 / 834

On to step 6:
When dividing 5812 by 834, we get 6 with a remainder of 808.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
Subtract 5004 from 5812 to get 808.
Grab the next digit (1) from the dividend, add it to 808, then carry on: 8081 / 834

Step 7:
834 can be fit into 8081 9 times, resulting in a remainder of 575.
Use 9 as the next digit of our solution. 
Result so far: 7669.0
Subtract 7506 from 8081 to get 575.
Append the next digit (0) from the dividend to 575 and continue with: 5750 / 834

On to step 8:
834 goes into 5750 6 times with a remainder of 746.
The number 6 becomes the next digit in our result. 
Result so far: 76696.0
If we subtract 5004 from 5750, we get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Step 9:
834 goes into 7460 8 times with a remainder of 788.
Put 8 as the next digit of the answer. 
Result so far: 76696.8
Subtracting 6672 from 7460 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Going ahead to step 10:
834 goes into 7880 9 times with a remainder of 374.
The number 9 becomes the next digit in our result. 
Result so far: 76696.89
If we subtract 7506 from 7880, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
3740 divided by 834 is 4 with a remainder of 404.
The next digit of our result is 4. 
Result so far: 76696.894
If we take 3336 away from 3740, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 12:
834 can be fit into 4040 4 times, resulting in a remainder of 704.
Record the quotient 4 as the next digit in the result. 
Result so far: 76696.8944
The remainder is 704 after subtracting 3336 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final result is 76696.8944 with a remainder of 0.00704.
