We're dividing 356242 by 81 
Let's see how many times 81 fits into 356242.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 81

Let's proceed to step 2:
81 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 81

Going ahead to step 3:
81 can be fit into 356 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 324 from 356, we get 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 81

Let's proceed to step 4:
When dividing 322 by 81, we get 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 243 from 322 and we're left with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 81

Let's proceed to step 5:
81 goes into 794 9 times with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 439.0
If we take 729 away from 794, we end up with 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 81

Let's proceed to step 6:
81 goes into 652 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 4398.0
The remainder is 4 after subtracting 648 from 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4398.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
81 goes into 400 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4398.04
If we take 324 away from 400, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
760 divided by 81 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 4398.049
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
When dividing 310 by 81, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 4398.0493
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
If we divide 670 by 81, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 4398.04938
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
81 goes into 220 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4398.049382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
81 goes into 580 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 4398.0493827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
130 divided by 81 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 4398.04938271
Deduct 81 from 130 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 4398.04938271, with a leftover of 4.9e-08.
