889216 ÷ 81 
We want to figure out the number of times 889216 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 81

Moving on to step 2:
When dividing 88 by 81, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 81 from 88 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 81

Advancing to step 3:
79 divided by 81 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 81

On to step 4:
The number 81 fits into 792 9 times, leaving a remainder of 63.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 729 from 792 and we're left with 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 81

Going ahead to step 5:
If we divide 631 by 81, we get 7 and a remainder of 64.
The next digit of our result is 7. 
Result so far: 1097.0
Deduct 567 from 631 and we're left with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 81

Going ahead to step 6:
81 goes into 646 7 times with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 10977.0
If we take 567 away from 646, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
If we divide 790 by 81, we get 9 and a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 10977.9
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 10977.97
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 81 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 10977.975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
If we divide 250 by 81, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 10977.9753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
The number 81 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 10977.9753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
700 divided by 81 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 10977.975308
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 10977.9753086
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
If we divide 340 by 81, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 10977.97530864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 10977.97530864, with a leftover of 1.6e-08.
