36358568 ÷ 81 
We're looking to find how many times 81 goes into 36358568.

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
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 81

Let's proceed to step 2:
When dividing 36 by 81, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 81

Advancing to step 3:
If we divide 363 by 81, we get 4 and a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 324 away from 363, we end up with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 81

On to step 4:
The number 81 fits into 395 4 times, leaving a remainder of 71.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 324 from 395 leaves us with 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 81

Going ahead to step 5:
When dividing 718 by 81, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 448.0
If we subtract 648 from 718, we get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 81

Step 6:
When dividing 705 by 81, we get 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 4488.0
If we subtract 648 from 705, we get 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 81

Moving on to step 7:
The number 81 fits into 576 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 44887.0
If we subtract 567 from 576, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 81

Moving on to step 8:
81 goes into 98 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 448871.0
Deduct 81 from 98 and we're left 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.

Going ahead to step 9:
The number 81 fits into 170 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 448871.2
Subtracting 162 from 170 leaves us 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.

Going ahead to step 10:
80 divided by 81 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 448871.2
If we subtract 0 from 80, we get 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 11:
800 divided by 81 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 448871.209
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.

Let's proceed to step 12:
81 goes into 710 8 times with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 448871.2098
If we take 648 away from 710, we end up 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.

Advancing to step 13:
620 divided by 81 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 448871.20987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 14:
When dividing 530 by 81, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 448871.209876
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.

Going ahead to step 15:
440 divided by 81 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 448871.2098765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 16:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 448871.20987654
If we take 324 away from 350, we end up 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.

The quotient of the division is 448871.20987654, and the remainder is 2.6e-08.
