Let's divide 469990 by 81
We're looking to find how many times 81 goes into 469990.

Advancing to 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
Deduct 0 from 4 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 81

Moving on to step 2:
When dividing 46 by 81, we get 0 with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 81

Let's proceed to step 3:
When dividing 469 by 81, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 405 from 469 and we're left with 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 81

Step 4:
81 can be fit into 649 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we take 648 away from 649, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 81

Step 5:
81 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 580.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 81

Step 6:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5802.0
Subtract 162 from 190 to 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.

Moving on to step 7:
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: 5802.3
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.

On to step 8:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 5802.34
Subtracting 324 from 370 leaves us 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.

Going ahead to step 9:
460 divided by 81 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5802.345
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
550 divided by 81 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 5802.3456
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
When dividing 640 by 81, we get 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 5802.34567
The remainder is 73 after subtracting 567 from 640.
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 12:
730 divided by 81 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5802.345679
If we subtract 729 from 730, we 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.

Advancing to step 13:
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: 5802.345679
If we take 0 away from 10, we end up 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.

Moving on to step 14:
100 divided by 81 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 5802.34567901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 5802.34567901, and the remainder is 1.9e-08.
