We're dividing 863539 by 11 
We're looking to find how many times 11 goes into 863539.

Moving on to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 11

On to step 2:
The number 11 fits into 86 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 11

On to step 3:
The number 11 fits into 93 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 88 away from 93, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 11

Moving on to step 4:
11 can be fit into 55 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
If we subtract 55 from 55, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 11

Going ahead to step 5:
When dividing 3 by 11, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 7850.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 11

Advancing to step 6:
If we divide 39 by 11, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 78503.0
If we take 33 away from 39, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 11 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 78503.5
If we take 55 away from 60, we end up 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.

On to step 8:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 78503.54
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 78503.545
If we subtract 55 from 60, 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.

Going ahead to step 10:
11 goes into 50 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 78503.5454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
11 can be fit into 60 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 78503.54545
If we take 55 away from 60, we end up 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 12:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 78503.545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 11 fits into 60 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 78503.5454545
The remainder is 5 after subtracting 55 from 60.
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 14:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 78503.54545454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 78503.54545454 and a remainder of 6e-09.
