52538560 ÷ 81 
Our goal is to divide 52538560 by 81.

Step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 81

Let's proceed to step 2:
52 divided by 81 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 81

Moving on to step 3:
The number 81 fits into 525 6 times, leaving a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 39 after subtracting 486 from 525.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 81

Advancing to step 4:
81 goes into 393 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 64.0
Deduct 324 from 393 and we're left with 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 81

On to step 5:
The number 81 fits into 698 8 times, leaving a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Subtract 648 from 698 to get 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 81

Advancing to step 6:
If we divide 505 by 81, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 6486.0
Subtract 486 from 505 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 81

Going ahead to step 7:
When dividing 196 by 81, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 64862.0
If we take 162 away from 196, we end up with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 81

Moving on to step 8:
When dividing 340 by 81, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 648624.0
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 81, we get 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 648624.1
If we take 81 away from 160, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 648624.19
Subtracting 729 from 790 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 11:
When dividing 610 by 81, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 648624.197
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
When dividing 430 by 81, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 648624.1975
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
When dividing 250 by 81, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 648624.19753
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
If we divide 70 by 81, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 648624.19753
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 15:
81 goes into 700 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 648624.1975308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
The number 81 fits into 520 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 648624.19753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 648624.19753086 with a balance of 3.4e-08.
