11684770 ÷ 561 
The aim is to understand the frequency of 561 in 11684770.

Moving on to step 1:
When dividing 1 by 561, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 561

Moving on to step 2:
561 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 561

Going ahead to step 3:
561 goes into 116 0 times with a remainder of 116.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 116, we get 116.
Fetch the next digit (8) from the dividend, attach it to 116 and continue: 1168 / 561

On to step 4:
When dividing 1168 by 561, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1122 from 1168 leaves us with 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 561

Going ahead to step 5:
If we divide 464 by 561, we get 0 and a remainder of 464.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 464 after subtracting 0 from 464.
Include the next digit (7) from the dividend after 464, then repeat: 4647 / 561

Going ahead to step 6:
561 goes into 4647 8 times with a remainder of 159.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Subtract 4488 from 4647 to get 159.
Bring next digit (7) of the dividend behind the 159 and repeat the process: 1597 / 561

Let's proceed to step 7:
The number 561 fits into 1597 2 times, leaving a remainder of 475.
The number 2 becomes the next digit in our result. 
Result so far: 2082.0
If we take 1122 away from 1597, we end up with 475.
Append the next digit (0) from the dividend to 475 and continue with: 4750 / 561

Advancing to step 8:
4750 divided by 561 is 8 with a remainder of 262.
Put 8 as the next digit of the answer. 
Result so far: 20828.0
If we take 4488 away from 4750, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 9:
2620 divided by 561 is 4 with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 20828.4
The remainder is 376 after subtracting 2244 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 10:
The number 561 fits into 3760 6 times, leaving a remainder of 394.
The next digit of our result is 6. 
Result so far: 20828.46
Subtracting 3366 from 3760 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 11:
The number 561 fits into 3940 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 20828.467
Subtracting 3927 from 3940 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
The number 561 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 20828.467
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 13:
If we divide 1300 by 561, we get 2 and a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 20828.46702
The remainder is 178 after subtracting 1122 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 14:
561 can be fit into 1780 3 times, resulting in a remainder of 97.
The next digit of our result is 3. 
Result so far: 20828.467023
If we subtract 1683 from 1780, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 15:
970 divided by 561 is 1 with a remainder of 409.
The next digit of our result is 1. 
Result so far: 20828.4670231
Subtracting 561 from 970 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 16:
561 goes into 4090 7 times with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 20828.46702317
If we take 3927 away from 4090, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Our division results in 20828.46702317 with a remaining 1.63e-07.
