We divide 428077 by 81
We want to figure out the number of times 428077 can be divided by 81.

Step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 81

Advancing to step 2:
81 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 81

On to step 3:
428 divided by 81 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 405 from 428 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 81

Step 4:
81 can be fit into 230 2 times, resulting in a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 162 from 230 leaves us with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 81

Step 5:
The number 81 fits into 687 8 times, leaving a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 528.0
Subtracting 648 from 687 leaves us with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 81

Moving on to step 6:
If we divide 397 by 81, we get 4 and a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 5284.0
Subtracting 324 from 397 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
81 can be fit into 730 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5284.9
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 81, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5284.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 81, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 5284.901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
81 can be fit into 190 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 5284.9012
Subtracting 162 from 190 leaves us 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.

Let's proceed to step 11:
When dividing 280 by 81, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 5284.90123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
If we divide 370 by 81, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 5284.901234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
460 divided by 81 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5284.9012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 14:
81 goes into 550 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5284.90123456
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 5284.90123456 with a remainder of 6.4e-08.
