51145146 ÷ 825 
Our goal is to divide 51145146 by 825.

Advancing to step 1:
825 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 825

Advancing to step 2:
825 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 825

On to step 3:
511 divided by 825 is 0 with a remainder of 511.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 511 after subtracting 0 from 511.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 825

Step 4:
825 goes into 5114 6 times with a remainder of 164.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4950 from 5114, we get 164.
Take the next digit (5) from the dividend and append it to 164, then repeat: 1645 / 825

Advancing to step 5:
1645 divided by 825 is 1 with a remainder of 820.
The next digit of our result is 1. 
Result so far: 61.0
Deduct 825 from 1645 and we're left with 820.
Include the next digit (1) from the dividend after 820, then repeat: 8201 / 825

Going ahead to step 6:
8201 divided by 825 is 9 with a remainder of 776.
The next digit of our result is 9. 
Result so far: 619.0
The remainder is 776 after subtracting 7425 from 8201.
Fetch the next digit (4) from the dividend, attach it to 776 and continue: 7764 / 825

Moving on to step 7:
825 goes into 7764 9 times with a remainder of 339.
Write down 9 as next digit of the result. 
Result so far: 6199.0
If we take 7425 away from 7764, we end up with 339.
Include the next digit (6) from the dividend after 339, then repeat: 3396 / 825

Let's proceed to step 8:
When dividing 3396 by 825, we get 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 61994.0
Subtracting 3300 from 3396 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
825 can be fit into 960 1 times, resulting in a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 61994.1
Subtract 825 from 960 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
The number 825 fits into 1350 1 times, leaving a remainder of 525.
The next digit of our result is 1. 
Result so far: 61994.11
The remainder is 525 after subtracting 825 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

In conclusion, the division gives 61994.11 with a balance of 0.525.
