644228 ÷ 11 
The aim is to understand the frequency of 11 in 644228.

Advancing to step 1:
When dividing 6 by 11, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 11

Let's proceed to step 2:
11 goes into 64 5 times 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.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 11

Let's proceed to step 3:
11 goes into 94 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we subtract 88 from 94, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 11

Going ahead to step 4:
If we divide 62 by 11, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 585.0
The remainder is 7 after subtracting 55 from 62.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 11

Advancing to step 5:
If we divide 72 by 11, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 5856.0
If we subtract 66 from 72, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 11

Let's proceed to step 6:
If we divide 68 by 11, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 58566.0
Subtract 66 from 68 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 11 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 58566.1
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 58566.18
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 58566.181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
If we divide 90 by 11, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 58566.1818
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
11 goes into 20 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 58566.18181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
11 can be fit into 90 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 58566.181818
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
20 divided by 11 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 58566.1818181
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
The number 11 fits into 90 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 58566.18181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 58566.18181818, and the remainder is 2e-09.
