We look at the division of 23900806 by 560 
The aim is to understand the frequency of 560 in 23900806.

Advancing to step 1:
560 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 560

On to step 2:
560 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 560

On to step 3:
560 goes into 239 0 times with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 239, we end up with 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 560

Let's proceed to step 4:
560 can be fit into 2390 4 times, resulting in a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2240 from 2390, we get 150.
Include the next digit (0) from the dividend after 150, then repeat: 1500 / 560

Going ahead to step 5:
560 goes into 1500 2 times with a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 1120 from 1500, we get 380.
Append the next digit (8) from the dividend to 380 and continue with: 3808 / 560

Let's proceed to step 6:
The number 560 fits into 3808 6 times, leaving a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 426.0
If we subtract 3360 from 3808, we get 448.
Bring next digit (0) of the dividend behind the 448 and repeat the process: 4480 / 560

On to step 7:
560 can be fit into 4480 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4268.0
Subtract 4480 from 4480 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 560

Step 8:
If we divide 6 by 560, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 42680.0
Subtract 0 from 6 to 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.

Advancing to step 9:
When dividing 60 by 560, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 42680.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
560 can be fit into 600 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 42680.01
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 560 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 42680.01
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
If we divide 4000 by 560, we get 7 and a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 42680.0107
If we take 3920 away from 4000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
560 goes into 800 1 times with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 42680.01071
The remainder is 240 after subtracting 560 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
2400 divided by 560 is 4 with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 42680.010714
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
560 can be fit into 1600 2 times, resulting in a remainder of 480.
Use 2 as the next digit of our solution. 
Result so far: 42680.0107142
The remainder is 480 after subtracting 1120 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
4800 divided by 560 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 42680.01071428
Subtracting 4480 from 4800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 42680.01071428 with a remaining 3.2e-07.
