917861 divided by 81 
We want to figure out the number of times 917861 can be divided by 81.

Advancing to step 1:
If we divide 9 by 81, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 81

Let's proceed to step 2:
If we divide 91 by 81, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 91 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 81

Advancing to step 3:
81 goes into 107 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 81 from 107 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 81

Moving on to step 4:
268 divided by 81 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 243 from 268, we get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 81

On to step 5:
81 can be fit into 256 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 1133.0
If we take 243 away from 256, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 81

Let's proceed to step 6:
When dividing 131 by 81, we get 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 11331.0
If we subtract 81 from 131, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
81 goes into 500 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 11331.6
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 81, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 11331.61
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 81, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 11331.617
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
81 goes into 230 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 11331.6172
Subtracting 162 from 230 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
680 divided by 81 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 11331.61728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 11331.617283
Subtracting 243 from 320 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 13:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 11331.6172839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 14:
410 divided by 81 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11331.61728395
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 11331.61728395 and a remainder of 5e-09.
