81393695 divided by 64 
Our goal is to divide 81393695 by 64.

Let's proceed to step 1:
8 divided by 64 is 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 / 64

On to step 2:
If we divide 81 by 64, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 64 away from 81, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 64

On to step 3:
64 can be fit into 173 2 times, resulting in a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 128 from 173 and we're left with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 64

Moving on to step 4:
If we divide 459 by 64, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 448 from 459 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 64

Going ahead to step 5:
The number 64 fits into 113 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1271.0
If we subtract 64 from 113, we get 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 64

Moving on to step 6:
64 goes into 496 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 12717.0
The remainder is 48 after subtracting 448 from 496.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 64

On to step 7:
When dividing 489 by 64, we get 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 127177.0
The remainder is 41 after subtracting 448 from 489.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 64

Advancing to step 8:
64 can be fit into 415 6 times, resulting in a remainder of 31.
The next digit of our result is 6. 
Result so far: 1271776.0
Deduct 384 from 415 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
The number 64 fits into 310 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 1271776.4
Deduct 256 from 310 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 64 fits into 540 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1271776.48
Deduct 512 from 540 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
If we divide 280 by 64, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 1271776.484
Subtract 256 from 280 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
240 divided by 64 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1271776.4843
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
64 goes into 480 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1271776.48437
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1271776.484375
Subtract 320 from 320 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1271776.484375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 16:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1271776.484375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1271776.484375, with a leftover of 0.0.
