87385814 divided by 81 
We're looking to find how many times 81 goes into 87385814.

Going ahead to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 81

Going ahead to step 2:
81 goes into 87 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 81 from 87 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 81

Advancing to step 3:
The number 81 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 63, we end up with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 81

Moving on to step 4:
The number 81 fits into 638 7 times, leaving a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 567 from 638 to get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 81

Step 5:
715 divided by 81 is 8 with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 1078.0
Subtract 648 from 715 to get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 81

On to step 6:
678 divided by 81 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 10788.0
The remainder is 30 after subtracting 648 from 678.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 81

Going ahead to step 7:
When dividing 301 by 81, we get 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 107883.0
Subtracting 243 from 301 leaves us with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 81

Moving on to step 8:
If we divide 584 by 81, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1078837.0
Deduct 567 from 584 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.

Step 9:
When dividing 170 by 81, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1078837.2
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
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: 1078837.2
Subtract 0 from 80 to 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.

Advancing to step 11:
If we divide 800 by 81, we get 9 and a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 1078837.209
If we take 729 away from 800, we end up with 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.
Use 8 as the next digit of our solution. 
Result so far: 1078837.2098
If we subtract 648 from 710, 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 13:
620 divided by 81 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 1078837.20987
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.

On to step 14:
The number 81 fits into 530 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1078837.209876
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.

Step 15:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1078837.2098765
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.

Let's proceed to step 16:
81 can be fit into 350 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 1078837.20987654
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 final result is 1078837.20987654 with a remainder of 2.6e-08.
