1584221 ÷ 250 
The aim is to understand the frequency of 250 in 1584221.

Step 1:
The number 250 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 250

Moving on to step 2:
250 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 250

Let's proceed to step 3:
158 divided by 250 is 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Take the next digit (4) from the dividend and append it to 158, then repeat: 1584 / 250

Going ahead to step 4:
1584 divided by 250 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 84 after subtracting 1500 from 1584.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 250

Moving on to step 5:
If we divide 842 by 250, we get 3 and a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 750 from 842 leaves us with 92.
Include the next digit (2) from the dividend after 92, then repeat: 922 / 250

Advancing to step 6:
250 can be fit into 922 3 times, resulting in a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 633.0
Subtract 750 from 922 to get 172.
Fetch the next digit (1) from the dividend, attach it to 172 and continue: 1721 / 250

Step 7:
250 can be fit into 1721 6 times, resulting in a remainder of 221.
Put 6 as the next digit of the answer. 
Result so far: 6336.0
Subtract 1500 from 1721 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 8:
250 can be fit into 2210 8 times, resulting in a remainder of 210.
Write down 8 as next digit of the result. 
Result so far: 6336.8
Subtracting 2000 from 2210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 9:
250 can be fit into 2100 8 times, resulting in a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 6336.88
Subtracting 2000 from 2100 leaves us 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.

The quotient of the division is 6336.88, and the remainder is 0.1.
