21673709 divided by 560 
The aim is to understand the frequency of 560 in 21673709.

On to step 1:
When dividing 2 by 560, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 560

Going ahead to step 2:
The number 560 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 560

Advancing to step 3:
560 goes into 216 0 times with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Fetch the next digit (7) from the dividend, attach it to 216 and continue: 2167 / 560

Step 4:
If we divide 2167 by 560, we get 3 and a remainder of 487.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1680 from 2167 to get 487.
Append the next digit (3) from the dividend to 487 and continue with: 4873 / 560

Moving on to step 5:
560 can be fit into 4873 8 times, resulting in a remainder of 393.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 4480 from 4873 to get 393.
Bring next digit (7) of the dividend behind the 393 and repeat the process: 3937 / 560

On to step 6:
When dividing 3937 by 560, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
If we subtract 3920 from 3937, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 560

Going ahead to step 7:
If we divide 170 by 560, we get 0 and a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 3870.0
Deduct 0 from 170 and we're left with 170.
Take the next digit (9) from the dividend and append it to 170, then repeat: 1709 / 560

On to step 8:
1709 divided by 560 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 38703.0
Subtract 1680 from 1709 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
If we divide 290 by 560, we get 0 and a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 38703.0
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
560 goes into 2900 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 38703.05
Deduct 2800 from 2900 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
The number 560 fits into 1000 1 times, leaving a remainder of 440.
Put 1 as the next digit of the answer. 
Result so far: 38703.051
The remainder is 440 after subtracting 560 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
When dividing 4400 by 560, we get 7 with a remainder of 480.
The number 7 becomes the next digit in our result. 
Result so far: 38703.0517
Subtracting 3920 from 4400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
560 goes into 4800 8 times with a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 38703.05178
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
When dividing 3200 by 560, we get 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 38703.051785
Subtracting 2800 from 3200 leaves us with 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 15:
If we divide 4000 by 560, we get 7 and a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 38703.0517857
Subtract 3920 from 4000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
800 divided by 560 is 1 with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 38703.05178571
Subtract 560 from 800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 38703.05178571 with a balance of 2.4e-07.
