Let's divide 489457 by 81
We want to figure out the number of times 489457 can be divided by 81.

Moving on to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 81

Going ahead to step 2:
81 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 81

On to step 3:
If we divide 489 by 81, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 486 away from 489, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 81

Going ahead to step 4:
34 divided by 81 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 81

Moving on to step 5:
345 divided by 81 is 4 with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 604.0
Subtracting 324 from 345 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 81

Moving on to step 6:
The number 81 fits into 217 2 times, leaving a remainder of 55.
The next digit of our result is 2. 
Result so far: 6042.0
If we take 162 away from 217, 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.

Moving on to step 7:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 6042.6
Subtracting 486 from 550 leaves us 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.

Let's proceed to step 8:
The number 81 fits into 640 7 times, leaving a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 6042.67
Deduct 567 from 640 and we're left 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.

Advancing to step 9:
The number 81 fits into 730 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 6042.679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6042.679
If we subtract 0 from 10, we get 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 11:
If we divide 100 by 81, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 6042.67901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 81 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6042.679012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
81 can be fit into 280 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 6042.6790123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
When dividing 370 by 81, we get 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 6042.67901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 6042.67901234 and a remainder of 4.6e-08.
