15459584 ÷ 638 
The aim is to understand the frequency of 638 in 15459584.

Going ahead to step 1:
The number 638 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 638

Moving on to step 2:
638 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 638

Moving on to step 3:
638 goes into 154 0 times with a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 638

On to step 4:
1545 divided by 638 is 2 with a remainder of 269.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1276 from 1545 and we're left with 269.
Take the next digit (9) from the dividend and append it to 269, then repeat: 2699 / 638

Step 5:
638 can be fit into 2699 4 times, resulting in a remainder of 147.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 2552 from 2699, we get 147.
Include the next digit (5) from the dividend after 147, then repeat: 1475 / 638

Moving on to step 6:
When dividing 1475 by 638, we get 2 with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 242.0
If we subtract 1276 from 1475, we get 199.
Include the next digit (8) from the dividend after 199, then repeat: 1998 / 638

Advancing to step 7:
If we divide 1998 by 638, we get 3 and a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 2423.0
If we take 1914 away from 1998, we end up with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 638

Advancing to step 8:
When dividing 844 by 638, we get 1 with a remainder of 206.
The next digit of our result is 1. 
Result so far: 24231.0
Subtracting 638 from 844 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
2060 divided by 638 is 3 with a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 24231.3
Deduct 1914 from 2060 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
638 can be fit into 1460 2 times, resulting in a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 24231.32
If we take 1276 away from 1460, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
638 goes into 1840 2 times with a remainder of 564.
Put 2 as the next digit of the answer. 
Result so far: 24231.322
If we subtract 1276 from 1840, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

In conclusion, the division gives 24231.322 with a balance of 0.0564.
