We look at the division of 356158 by 81 
Our goal is to divide 356158 by 81.

On to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 81

Going ahead to step 2:
The number 81 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 81

Let's proceed to step 3:
If we divide 356 by 81, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 324 from 356 to get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 81

Moving on to step 4:
321 divided by 81 is 3 with a remainder of 78.
The next digit of our result is 3. 
Result so far: 43.0
If we take 243 away from 321, we end up with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 81

Advancing to step 5:
81 can be fit into 785 9 times, resulting in a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 439.0
Subtracting 729 from 785 leaves us with 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 81

Step 6:
When dividing 568 by 81, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4397.0
Subtracting 567 from 568 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4397.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 81, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 4397.01
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 81, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4397.012
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.

Going ahead to step 10:
280 divided by 81 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 4397.0123
Deduct 243 from 280 and we're left with 37.
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 11:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4397.01234
Deduct 324 from 370 and we're left 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.

Advancing to step 12:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4397.012345
Deduct 405 from 460 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
81 goes into 550 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 4397.0123456
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
When dividing 640 by 81, we get 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 4397.01234567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 4397.01234567, with a leftover of 7.3e-08.
