15810740 ÷ 564 
The aim is to understand the frequency of 564 in 15810740.

Step 1:
The number 564 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 564

Moving on to step 2:
15 divided by 564 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 564

Moving on to step 3:
564 goes into 158 0 times with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 564

Let's proceed to step 4:
If we divide 1581 by 564, we get 2 and a remainder of 453.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1128 from 1581 leaves us with 453.
Fetch the next digit (0) from the dividend, attach it to 453 and continue: 4530 / 564

Moving on to step 5:
When dividing 4530 by 564, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 18 after subtracting 4512 from 4530.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 564

Let's proceed to step 6:
564 can be fit into 187 0 times, resulting in a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Deduct 0 from 187 and we're left with 187.
Include the next digit (4) from the dividend after 187, then repeat: 1874 / 564

Let's proceed to step 7:
If we divide 1874 by 564, we get 3 and a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 2803.0
If we take 1692 away from 1874, we end up with 182.
Bring next digit (0) of the dividend behind the 182 and repeat the process: 1820 / 564

Let's proceed to step 8:
1820 divided by 564 is 3 with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 28033.0
The remainder is 128 after subtracting 1692 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
564 goes into 1280 2 times with a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 28033.2
Subtract 1128 from 1280 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
The number 564 fits into 1520 2 times, leaving a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 28033.22
Subtracting 1128 from 1520 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

After the division, we end up with 28033.22 and a remainder of 0.392.
