65192561 ÷ 838 
We want to figure out the number of times 65192561 can be divided by 838.

On to step 1:
838 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 838

On to step 2:
838 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 838

Let's proceed to step 3:
838 goes into 651 0 times with a remainder of 651.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 651, we get 651.
Include the next digit (9) from the dividend after 651, then repeat: 6519 / 838

Going ahead to step 4:
If we divide 6519 by 838, we get 7 and a remainder of 653.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 653 after subtracting 5866 from 6519.
Bring next digit (2) of the dividend behind the 653 and repeat the process: 6532 / 838

Advancing to step 5:
838 goes into 6532 7 times with a remainder of 666.
Use 7 as the next digit of our solution. 
Result so far: 77.0
The remainder is 666 after subtracting 5866 from 6532.
Take the next digit (5) from the dividend and append it to 666, then repeat: 6665 / 838

Moving on to step 6:
838 goes into 6665 7 times with a remainder of 799.
The number 7 becomes the next digit in our result. 
Result so far: 777.0
Subtract 5866 from 6665 to get 799.
Fetch the next digit (6) from the dividend, attach it to 799 and continue: 7996 / 838

Step 7:
838 goes into 7996 9 times with a remainder of 454.
Use 9 as the next digit of our solution. 
Result so far: 7779.0
If we take 7542 away from 7996, we end up with 454.
Append the next digit (1) from the dividend to 454 and continue with: 4541 / 838

Advancing to step 8:
If we divide 4541 by 838, we get 5 and a remainder of 351.
The next digit of our result is 5. 
Result so far: 77795.0
Subtract 4190 from 4541 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 9:
If we divide 3510 by 838, we get 4 and a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 77795.4
The remainder is 158 after subtracting 3352 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 10:
When dividing 1580 by 838, we get 1 with a remainder of 742.
Write down 1 as next digit of the result. 
Result so far: 77795.41
The remainder is 742 after subtracting 838 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 11:
If we divide 7420 by 838, we get 8 and a remainder of 716.
Put 8 as the next digit of the answer. 
Result so far: 77795.418
Subtract 6704 from 7420 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 12:
If we divide 7160 by 838, we get 8 and a remainder of 456.
The next digit of our result is 8. 
Result so far: 77795.4188
Deduct 6704 from 7160 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

In conclusion, the division gives 77795.4188 with a balance of 0.00456.
