643926 divided by 11 
Our goal is to divide 643926 by 11.

Step 1:
6 divided by 11 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 11

On to step 2:
When dividing 64 by 11, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 55 away from 64, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 11

Step 3:
If we divide 93 by 11, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Deduct 88 from 93 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 11

Advancing to step 4:
11 goes into 59 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 585.0
The remainder is 4 after subtracting 55 from 59.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 11

Step 5:
If we divide 42 by 11, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 5853.0
The remainder is 9 after subtracting 33 from 42.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 11

Let's proceed to step 6:
The number 11 fits into 96 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 58538.0
If we take 88 away from 96, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 11 fits into 80 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 58538.7
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
When dividing 30 by 11, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 58538.72
If we take 22 away from 30, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 11 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 58538.727
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 58538.7272
If we subtract 22 from 30, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
11 goes into 80 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 58538.72727
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
30 divided by 11 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 58538.727272
Subtract 22 from 30 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 58538.7272727
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
11 can be fit into 30 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 58538.72727272
The remainder is 8 after subtracting 22 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 58538.72727272, with a leftover of 8e-09.
