Let's divide 6460177 by 81
We want to figure out the number of times 6460177 can be divided by 81.

Moving on to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 81

Step 2:
The number 81 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 81

Step 3:
The number 81 fits into 646 7 times, leaving a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 79 after subtracting 567 from 646.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 81

Step 4:
When dividing 790 by 81, we get 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 729 from 790 to get 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 81

Going ahead to step 5:
When dividing 611 by 81, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 797.0
Subtract 567 from 611 to get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 81

Step 6:
81 goes into 447 5 times with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 7975.0
If we subtract 405 from 447, we get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 81

Let's proceed to step 7:
When dividing 427 by 81, we get 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 79755.0
The remainder is 22 after subtracting 405 from 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
81 goes into 220 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 79755.2
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 79755.27
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
If we divide 130 by 81, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 79755.271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 11:
490 divided by 81 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 79755.2716
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 81, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 79755.2716
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 79755.271604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
The number 81 fits into 760 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 79755.2716049
Subtracting 729 from 760 leaves us 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.

Step 15:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 79755.27160493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 79755.27160493 and a remainder of 6.7e-08.
