We divide 641920 by 11
We're looking to find how many times 11 goes into 641920.

Step 1:
When dividing 6 by 11, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 11

On to step 2:
When dividing 64 by 11, we get 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 55 from 64 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 11

Step 3:
11 goes into 91 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 58.0
If we take 88 away from 91, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 11

Let's proceed to step 4:
11 goes into 39 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 583.0
If we take 33 away from 39, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 11

On to step 5:
When dividing 62 by 11, we get 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 5835.0
If we subtract 55 from 62, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 11

Advancing to step 6:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 58356.0
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 58356.3
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
11 can be fit into 70 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 58356.36
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
11 goes into 40 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 58356.363
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
70 divided by 11 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 58356.3636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 58356.36363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
When dividing 70 by 11, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 58356.363636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
11 goes into 40 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 58356.3636363
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
When dividing 70 by 11, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 58356.36363636
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 58356.36363636 with a balance of 4e-09.
