669993 divided by 11 
The aim is to understand the frequency of 11 in 669993.

Let's proceed to step 1:
If we divide 6 by 11, we get 0 and 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 11

Advancing to step 2:
The number 11 fits into 66 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 66 from 66 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 11

Step 3:
11 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 11

Let's proceed to step 4:
11 can be fit into 99 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 609.0
Deduct 99 from 99 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 11

Advancing to step 5:
11 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 6090.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 11

Advancing to step 6:
The number 11 fits into 93 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 60908.0
Subtracting 88 from 93 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 7:
11 goes into 50 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 60908.4
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.

Advancing to step 8:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 60908.45
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 9:
When dividing 50 by 11, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 60908.454
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.

Let's proceed to step 10:
When dividing 60 by 11, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 60908.4545
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.

Step 11:
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: 60908.45454
If we subtract 44 from 50, we 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.

Let's proceed to step 12:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 60908.454545
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.

Moving on to step 13:
When dividing 50 by 11, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 60908.4545454
Deduct 44 from 50 and we're left 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.

Step 14:
If we divide 60 by 11, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 60908.45454545
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.

The final result is 60908.45454545 with a remainder of 5e-09.
