We look at the division of 472490 by 81 
We're looking to find how many times 81 goes into 472490.

Step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 81

Going ahead to step 2:
47 divided by 81 is 0 with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 81

Advancing to step 3:
472 divided by 81 is 5 with a remainder of 67.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 67 after subtracting 405 from 472.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 81

On to step 4:
If we divide 674 by 81, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we subtract 648 from 674, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 81

Let's proceed to step 5:
269 divided by 81 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 583.0
If we subtract 243 from 269, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 81

Going ahead to step 6:
260 divided by 81 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 5833.0
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
81 goes into 170 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 5833.2
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.

Moving on to step 8:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 5833.2
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
81 goes into 800 9 times with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 5833.209
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
When dividing 710 by 81, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 5833.2098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
When dividing 620 by 81, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 5833.20987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 12:
If we divide 530 by 81, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 5833.209876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
440 divided by 81 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5833.2098765
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
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: 5833.20987654
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.

Our division results in 5833.20987654 with a remaining 2.6e-08.
