We divide 51640865 by 819
We're looking to find how many times 819 goes into 51640865.

Going ahead to step 1:
5 divided by 819 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 819

Step 2:
The number 819 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 819

Moving on to step 3:
If we divide 516 by 819, we get 0 and a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Append the next digit (4) from the dividend to 516 and continue with: 5164 / 819

Moving on to step 4:
819 goes into 5164 6 times with a remainder of 250.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4914 from 5164 and we're left with 250.
Append the next digit (0) from the dividend to 250 and continue with: 2500 / 819

Step 5:
When dividing 2500 by 819, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 63.0
Subtracting 2457 from 2500 leaves us with 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 819

Let's proceed to step 6:
438 divided by 819 is 0 with a remainder of 438.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
If we subtract 0 from 438, we get 438.
Include the next digit (6) from the dividend after 438, then repeat: 4386 / 819

Moving on to step 7:
If we divide 4386 by 819, we get 5 and a remainder of 291.
The next digit of our result is 5. 
Result so far: 6305.0
Subtract 4095 from 4386 to get 291.
Take the next digit (5) from the dividend and append it to 291, then repeat: 2915 / 819

Advancing to step 8:
819 goes into 2915 3 times with a remainder of 458.
The next digit of our result is 3. 
Result so far: 63053.0
If we subtract 2457 from 2915, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 9:
819 can be fit into 4580 5 times, resulting in a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 63053.5
Deduct 4095 from 4580 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 10:
When dividing 4850 by 819, we get 5 with a remainder of 755.
Record the quotient 5 as the next digit in the result. 
Result so far: 63053.55
Subtracting 4095 from 4850 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

In conclusion, the division gives 63053.55 with a balance of 0.755.
