We're dividing 43686 by 11 
We're looking to find how many times 11 goes into 43686.

Moving on to step 1:
The number 11 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 11

On to step 2:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 33 from 43 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 11

Moving on to step 3:
11 can be fit into 106 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 99 away from 106, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 11

Step 4:
The number 11 fits into 78 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 397.0
Subtracting 77 from 78 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 11

Advancing to step 5:
11 can be fit into 16 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 3971.0
If we take 11 away from 16, 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.

Advancing to step 6:
50 divided by 11 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 3971.4
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.

On to step 7:
11 can be fit into 60 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3971.45
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.

Step 8:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3971.454
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.

On to step 9:
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: 3971.4545
Subtracting 55 from 60 leaves us 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.

Going ahead to step 10:
If we divide 50 by 11, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 3971.45454
Subtracting 44 from 50 leaves us 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 11:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3971.454545
Subtracting 55 from 60 leaves us 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.

Going ahead to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3971.4545454
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.

On to step 13:
If we divide 60 by 11, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3971.45454545
Subtract 55 from 60 to 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.

In conclusion, the division gives 3971.45454545 with a balance of 5e-09.
