We're dividing 424290 by 81 
We want to figure out the number of times 424290 can be divided by 81.

Moving on to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 81

On to step 2:
When dividing 42 by 81, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 81

Moving on to step 3:
When dividing 424 by 81, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 405 from 424 and we're left with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 81

Let's proceed to step 4:
81 can be fit into 192 2 times, resulting in a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 162 from 192 leaves us with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 81

Step 5:
The number 81 fits into 309 3 times, leaving a remainder of 66.
The next digit of our result is 3. 
Result so far: 523.0
If we subtract 243 from 309, we get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 81

Advancing to step 6:
81 goes into 660 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5238.0
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
81 goes into 120 1 times with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 5238.1
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 5238.14
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
81 goes into 660 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5238.148
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 81, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5238.1481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
When dividing 390 by 81, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 5238.14814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5238.148148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 81, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 5238.1481481
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 14:
390 divided by 81 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 5238.14814814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 5238.14814814 with a balance of 6.6e-08.
