We divide 64035855 by 81
We're looking to find how many times 81 goes into 64035855.

On to step 1:
81 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 81

Moving on to step 2:
81 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 81

On to step 3:
When dividing 640 by 81, we get 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 567 from 640 to get 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 81

Going ahead to step 4:
The number 81 fits into 733 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 729 from 733 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 81

On to step 5:
If we divide 45 by 81, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 81

Step 6:
81 goes into 458 5 times with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 7905.0
The remainder is 53 after subtracting 405 from 458.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 81

Advancing to step 7:
81 can be fit into 535 6 times, resulting in a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 79056.0
If we take 486 away from 535, we end up with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 81

Advancing to step 8:
81 goes into 495 6 times with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 790566.0
If we take 486 away from 495, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 790566.1
Subtract 81 from 90 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 790566.11
If we subtract 81 from 90, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 790566.11 with a remainder of 0.009.
