Let's divide 64577429 by 81
Let's see how many times 81 fits into 64577429.

Moving on to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 81

Let's proceed to step 2:
When dividing 64 by 81, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 81

Advancing to step 3:
When dividing 645 by 81, we get 7 with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 78 after subtracting 567 from 645.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 81

On to step 4:
81 goes into 787 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 729 from 787 leaves us with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 81

Step 5:
When dividing 587 by 81, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 797.0
If we take 567 away from 587, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 81

Moving on to step 6:
When dividing 204 by 81, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 7972.0
Subtracting 162 from 204 leaves us with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 81

Going ahead to step 7:
If we divide 422 by 81, we get 5 and a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 79725.0
Subtracting 405 from 422 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 81

Let's proceed to step 8:
The number 81 fits into 179 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 797252.0
Deduct 162 from 179 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 797252.2
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 81 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 797252.2
If we take 0 away from 80, we end up with 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 11:
The number 81 fits into 800 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 797252.209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
If we divide 710 by 81, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 797252.2098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
The number 81 fits into 620 7 times, leaving a remainder of 53.
The next digit of our result is 7. 
Result so far: 797252.20987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 797252.209876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 797252.2098765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 16:
When dividing 350 by 81, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 797252.20987654
Subtracting 324 from 350 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 797252.20987654 and a remainder of 2.6e-08.
