Let's divide 356345 by 81
We're looking to find how many times 81 goes into 356345.

Step 1:
81 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 81

Let's proceed to step 2:
81 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 81

On to step 3:
When dividing 356 by 81, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 324 from 356 and we're left with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 81

On to step 4:
81 goes into 323 3 times with a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 80 after subtracting 243 from 323.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 81

Going ahead to step 5:
The number 81 fits into 804 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 439.0
Deduct 729 from 804 and we're left with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 81

Moving on to step 6:
If we divide 755 by 81, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 4399.0
The remainder is 26 after subtracting 729 from 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
260 divided by 81 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 4399.3
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
If we divide 170 by 81, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4399.32
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
81 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4399.32
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 81 fits into 800 9 times, leaving a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 4399.3209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
81 goes into 710 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 4399.32098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
620 divided by 81 is 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 4399.320987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4399.3209876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4399.32098765
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 4399.32098765 with a remaining 3.5e-08.
