68445447 divided by 561 
The aim is to understand the frequency of 561 in 68445447.

Advancing to step 1:
If we divide 6 by 561, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 561

Let's proceed to step 2:
If we divide 68 by 561, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 561

Going ahead to step 3:
561 goes into 684 1 times with a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 561 from 684 leaves us with 123.
Append the next digit (4) from the dividend to 123 and continue with: 1234 / 561

Let's proceed to step 4:
1234 divided by 561 is 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1122 away from 1234, we end up with 112.
Append the next digit (5) from the dividend to 112 and continue with: 1125 / 561

Let's proceed to step 5:
When dividing 1125 by 561, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtract 1122 from 1125 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 561

Moving on to step 6:
The number 561 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 561

On to step 7:
When dividing 344 by 561, we get 0 with a remainder of 344.
Put 0 as the next digit of the answer. 
Result so far: 12200.0
If we take 0 away from 344, we end up with 344.
Take the next digit (7) from the dividend and append it to 344, then repeat: 3447 / 561

On to step 8:
561 can be fit into 3447 6 times, resulting in a remainder of 81.
The next digit of our result is 6. 
Result so far: 122006.0
Deduct 3366 from 3447 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
If we divide 810 by 561, we get 1 and a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 122006.1
Subtract 561 from 810 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 10:
2490 divided by 561 is 4 with a remainder of 246.
Record the quotient 4 as the next digit in the result. 
Result so far: 122006.14
If we subtract 2244 from 2490, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 11:
When dividing 2460 by 561, we get 4 with a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 122006.144
The remainder is 216 after subtracting 2244 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 122006.144 with a remainder of 0.0216.
