We look at the division of 81259016 by 838 
Let's see how many times 838 fits into 81259016.

Let's proceed to step 1:
When dividing 8 by 838, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 838

Advancing to step 2:
When dividing 81 by 838, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 838

Step 3:
812 divided by 838 is 0 with a remainder of 812.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 812 to get 812.
Bring next digit (5) of the dividend behind the 812 and repeat the process: 8125 / 838

Going ahead to step 4:
When dividing 8125 by 838, we get 9 with a remainder of 583.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7542 away from 8125, we end up with 583.
Include the next digit (9) from the dividend after 583, then repeat: 5839 / 838

Step 5:
838 goes into 5839 6 times with a remainder of 811.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we take 5028 away from 5839, we end up with 811.
Grab the next digit (0) from the dividend, add it to 811, then carry on: 8110 / 838

Going ahead to step 6:
838 goes into 8110 9 times with a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 969.0
Deduct 7542 from 8110 and we're left with 568.
Fetch the next digit (1) from the dividend, attach it to 568 and continue: 5681 / 838

Moving on to step 7:
5681 divided by 838 is 6 with a remainder of 653.
Record the quotient 6 as the next digit in the result. 
Result so far: 9696.0
If we take 5028 away from 5681, we end up with 653.
Include the next digit (6) from the dividend after 653, then repeat: 6536 / 838

Advancing to step 8:
If we divide 6536 by 838, we get 7 and a remainder of 670.
Use 7 as the next digit of our solution. 
Result so far: 96967.0
If we take 5866 away from 6536, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 9:
When dividing 6700 by 838, we get 7 with a remainder of 834.
The number 7 becomes the next digit in our result. 
Result so far: 96967.7
Subtracting 5866 from 6700 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Advancing to step 10:
838 goes into 8340 9 times with a remainder of 798.
The next digit of our result is 9. 
Result so far: 96967.79
Deduct 7542 from 8340 and we're left with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 11:
838 goes into 7980 9 times with a remainder of 438.
Write down 9 as next digit of the result. 
Result so far: 96967.799
If we subtract 7542 from 7980, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final result is 96967.799 with a remainder of 0.0438.
