81195413 ÷ 512 
Let's see how many times 512 fits into 81195413.

On to step 1:
When dividing 8 by 512, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 512

Step 2:
512 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 512

Step 3:
If we divide 811 by 512, we get 1 and a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 512 from 811 and we're left with 299.
Bring next digit (9) of the dividend behind the 299 and repeat the process: 2999 / 512

Going ahead to step 4:
2999 divided by 512 is 5 with a remainder of 439.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2560 away from 2999, we end up with 439.
Append the next digit (5) from the dividend to 439 and continue with: 4395 / 512

On to step 5:
The number 512 fits into 4395 8 times, leaving a remainder of 299.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 299 after subtracting 4096 from 4395.
Append the next digit (4) from the dividend to 299 and continue with: 2994 / 512

Let's proceed to step 6:
If we divide 2994 by 512, we get 5 and a remainder of 434.
Use 5 as the next digit of our solution. 
Result so far: 1585.0
Subtracting 2560 from 2994 leaves us with 434.
Append the next digit (1) from the dividend to 434 and continue with: 4341 / 512

Moving on to step 7:
512 goes into 4341 8 times with a remainder of 245.
Write down 8 as next digit of the result. 
Result so far: 15858.0
Deduct 4096 from 4341 and we're left with 245.
Grab the next digit (3) from the dividend, add it to 245, then carry on: 2453 / 512

On to step 8:
2453 divided by 512 is 4 with a remainder of 405.
Record the quotient 4 as the next digit in the result. 
Result so far: 158584.0
Subtracting 2048 from 2453 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
If we divide 4050 by 512, we get 7 and a remainder of 466.
Write down 7 as next digit of the result. 
Result so far: 158584.7
If we take 3584 away from 4050, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 10:
512 goes into 4660 9 times with a remainder of 52.
The next digit of our result is 9. 
Result so far: 158584.79
The remainder is 52 after subtracting 4608 from 4660.
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 11:
520 divided by 512 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 158584.791
Subtract 512 from 520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 512, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 158584.791
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
The number 512 fits into 800 1 times, leaving a remainder of 288.
The next digit of our result is 1. 
Result so far: 158584.79101
If we take 512 away from 800, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
512 goes into 2880 5 times with a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 158584.791015
If we take 2560 away from 2880, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
The number 512 fits into 3200 6 times, leaving a remainder of 128.
The next digit of our result is 6. 
Result so far: 158584.7910156
If we subtract 3072 from 3200, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
The number 512 fits into 1280 2 times, leaving a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 158584.79101562
The remainder is 256 after subtracting 1024 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 158584.79101562 with a balance of 2.56e-07.
