We look at the division of 356078 by 81 
Let's see how many times 81 fits into 356078.

Going ahead to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 81

Moving on to step 2:
If we divide 35 by 81, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 81

Let's proceed to step 3:
The number 81 fits into 356 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 324 from 356 and we're left with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 81

Going ahead to step 4:
81 can be fit into 320 3 times, resulting in a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 243 away from 320, we end up with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 81

Step 5:
81 goes into 777 9 times with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 439.0
Deduct 729 from 777 and we're left with 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 81

Step 6:
81 can be fit into 488 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 4396.0
Deduct 486 from 488 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
81 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4396.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 4396.02
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 81, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4396.024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
When dividing 560 by 81, we get 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 4396.0246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
81 can be fit into 740 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4396.02469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 4396.024691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
If we divide 290 by 81, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 4396.0246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
81 goes into 470 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 4396.02469135
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 4396.02469135 with a remaining 6.5e-08.
