We're dividing 21506546 by 582 
The aim is to understand the frequency of 582 in 21506546.

Going ahead to step 1:
When dividing 2 by 582, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 582

Moving on to step 2:
If we divide 21 by 582, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 582

Going ahead to step 3:
If we divide 215 by 582, we get 0 and a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 215 and we're left with 215.
Append the next digit (0) from the dividend to 215 and continue with: 2150 / 582

On to step 4:
The number 582 fits into 2150 3 times, leaving a remainder of 404.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1746 away from 2150, we end up with 404.
Fetch the next digit (6) from the dividend, attach it to 404 and continue: 4046 / 582

Let's proceed to step 5:
582 can be fit into 4046 6 times, resulting in a remainder of 554.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 3492 from 4046 leaves us with 554.
Include the next digit (5) from the dividend after 554, then repeat: 5545 / 582

Moving on to step 6:
582 can be fit into 5545 9 times, resulting in a remainder of 307.
The next digit of our result is 9. 
Result so far: 369.0
The remainder is 307 after subtracting 5238 from 5545.
Take the next digit (4) from the dividend and append it to 307, then repeat: 3074 / 582

Step 7:
582 goes into 3074 5 times with a remainder of 164.
Record the quotient 5 as the next digit in the result. 
Result so far: 3695.0
The remainder is 164 after subtracting 2910 from 3074.
Include the next digit (6) from the dividend after 164, then repeat: 1646 / 582

Let's proceed to step 8:
When dividing 1646 by 582, we get 2 with a remainder of 482.
Record the quotient 2 as the next digit in the result. 
Result so far: 36952.0
If we take 1164 away from 1646, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 9:
582 goes into 4820 8 times with a remainder of 164.
The next digit of our result is 8. 
Result so far: 36952.8
If we take 4656 away from 4820, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
1640 divided by 582 is 2 with a remainder of 476.
Write down 2 as next digit of the result. 
Result so far: 36952.82
If we take 1164 away from 1640, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 11:
If we divide 4760 by 582, we get 8 and a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 36952.828
If we take 4656 away from 4760, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
The number 582 fits into 1040 1 times, leaving a remainder of 458.
The number 1 becomes the next digit in our result. 
Result so far: 36952.8281
Subtracting 582 from 1040 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 13:
If we divide 4580 by 582, we get 7 and a remainder of 506.
The number 7 becomes the next digit in our result. 
Result so far: 36952.82817
If we take 4074 away from 4580, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 14:
582 goes into 5060 8 times with a remainder of 404.
The next digit of our result is 8. 
Result so far: 36952.828178
If we take 4656 away from 5060, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 15:
582 can be fit into 4040 6 times, resulting in a remainder of 548.
Put 6 as the next digit of the answer. 
Result so far: 36952.8281786
The remainder is 548 after subtracting 3492 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 16:
582 can be fit into 5480 9 times, resulting in a remainder of 242.
Record the quotient 9 as the next digit in the result. 
Result so far: 36952.82817869
If we take 5238 away from 5480, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 36952.82817869 and a remainder of 2.42e-07.
