860306 divided by 81 
We're looking to find how many times 81 goes into 860306.

Let's proceed to step 1:
81 goes into 8 0 times 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

On to step 2:
When dividing 86 by 81, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 81 from 86, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 81

Moving on to step 3:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 81

Moving on to step 4:
The number 81 fits into 503 6 times, leaving a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 486 from 503 leaves us with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 81

Advancing to step 5:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1062.0
The remainder is 8 after subtracting 162 from 170.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

Going ahead to step 6:
81 can be fit into 86 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10621.0
Deduct 81 from 86 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 81, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10621.0
If we subtract 0 from 50, 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.

Moving on to step 8:
When dividing 500 by 81, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 10621.06
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 81, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 10621.061
Subtract 81 from 140 to 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.

Moving on to step 10:
590 divided by 81 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 10621.0617
Deduct 567 from 590 and we're left 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 11:
If we divide 230 by 81, we get 2 and a remainder of 68.
The next digit of our result is 2. 
Result so far: 10621.06172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
If we divide 680 by 81, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 10621.061728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
81 goes into 320 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 10621.0617283
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 10621.06172839
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 10621.06172839 and a remainder of 4.1e-08.
