Let's divide 71566447 by 638
The aim is to understand the frequency of 638 in 71566447.

Let's proceed to step 1:
7 divided by 638 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 638

Going ahead to step 2:
If we divide 71 by 638, we get 0 and a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 638

On to step 3:
The number 638 fits into 715 1 times, leaving a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 638 away from 715, we end up with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 638

On to step 4:
776 divided by 638 is 1 with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 638 from 776 leaves us with 138.
Append the next digit (6) from the dividend to 138 and continue with: 1386 / 638

Let's proceed to step 5:
638 can be fit into 1386 2 times, resulting in a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Deduct 1276 from 1386 and we're left with 110.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 638

Let's proceed to step 6:
638 can be fit into 1104 1 times, resulting in a remainder of 466.
Record the quotient 1 as the next digit in the result. 
Result so far: 1121.0
Subtracting 638 from 1104 leaves us with 466.
Fetch the next digit (4) from the dividend, attach it to 466 and continue: 4664 / 638

Advancing to step 7:
638 can be fit into 4664 7 times, resulting in a remainder of 198.
Use 7 as the next digit of our solution. 
Result so far: 11217.0
If we subtract 4466 from 4664, we get 198.
Take the next digit (7) from the dividend and append it to 198, then repeat: 1987 / 638

Advancing to step 8:
1987 divided by 638 is 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 112173.0
Subtracting 1914 from 1987 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
638 can be fit into 730 1 times, resulting in a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 112173.1
The remainder is 92 after subtracting 638 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
The number 638 fits into 920 1 times, leaving a remainder of 282.
The next digit of our result is 1. 
Result so far: 112173.11
The remainder is 282 after subtracting 638 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

After the division, we end up with 112173.11 and a remainder of 0.282.
