21201249 ÷ 530 
The aim is to understand the frequency of 530 in 21201249.

Advancing to step 1:
530 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 530

Let's proceed to step 2:
The number 530 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 530

Going ahead to step 3:
If we divide 212 by 530, we get 0 and a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Grab the next digit (0) from the dividend, add it to 212, then carry on: 2120 / 530

On to step 4:
The number 530 fits into 2120 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 2120 from 2120 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 530

Step 5:
The number 530 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 530

Let's proceed to step 6:
When dividing 12 by 530, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 400.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 530

Advancing to step 7:
The number 530 fits into 124 0 times, leaving a remainder of 124.
The next digit of our result is 0. 
Result so far: 4000.0
Subtracting 0 from 124 leaves us with 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 530

Advancing to step 8:
1249 divided by 530 is 2 with a remainder of 189.
Use 2 as the next digit of our solution. 
Result so far: 40002.0
Subtract 1060 from 1249 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
1890 divided by 530 is 3 with a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 40002.3
Subtracting 1590 from 1890 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
530 goes into 3000 5 times with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 40002.35
If we take 2650 away from 3000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 11:
3500 divided by 530 is 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 40002.356
The remainder is 320 after subtracting 3180 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
3200 divided by 530 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 40002.3566
Subtract 3180 from 3200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 40002.3566, and the remainder is 0.0002.
