358406 divided by 81 
Let's see how many times 81 fits into 358406.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 81

Going ahead to step 2:
35 divided by 81 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 81

Moving on to step 3:
The number 81 fits into 358 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 324 from 358 leaves us with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 81

On to step 4:
81 can be fit into 344 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 324 from 344, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 81

Let's proceed to step 5:
200 divided by 81 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 442.0
The remainder is 38 after subtracting 162 from 200.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 81

Moving on to step 6:
The number 81 fits into 386 4 times, leaving a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 4424.0
If we subtract 324 from 386, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
If we divide 620 by 81, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 4424.7
Subtract 567 from 620 to get 53.
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 8:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4424.76
Subtracting 486 from 530 leaves us 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 9:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4424.765
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.

On to step 10:
350 divided by 81 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4424.7654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
260 divided by 81 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 4424.76543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
81 can be fit into 170 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4424.765432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 4424.765432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 4424.76543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 4424.76543209, with a leftover of 7.1e-08.
