We divide 235421 by 11
We want to figure out the number of times 235421 can be divided by 11.

Step 1:
The number 11 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 11

Step 2:
23 divided by 11 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 22 from 23 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 11

Going ahead to step 3:
15 divided by 11 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 11 from 15 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 11

Advancing to step 4:
11 goes into 44 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtract 44 from 44 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 11

Let's proceed to step 5:
The number 11 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 2140.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 11

On to step 6:
If we divide 21 by 11, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 21401.0
If we take 11 away from 21, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
11 can be fit into 100 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 21401.9
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 21401.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
11 goes into 100 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 21401.909
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
If we divide 10 by 11, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21401.909
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 21401.90909
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21401.90909
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 11 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 21401.9090909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
If we divide 10 by 11, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 21401.9090909
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 21401.9090909 with a remaining 1e-08.
