Let's divide 638561 by 32
The aim is to understand the frequency of 32 in 638561.

On to step 1:
6 divided by 32 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 32

Going ahead to step 2:
The number 32 fits into 63 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 31 after subtracting 32 from 63.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 32

Moving on to step 3:
32 can be fit into 318 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 288 from 318, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 32

Advancing to step 4:
The number 32 fits into 305 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
If we take 288 away from 305, we end up with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 32

Going ahead to step 5:
176 divided by 32 is 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1995.0
Deduct 160 from 176 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 32

Advancing to step 6:
If we divide 161 by 32, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 19955.0
If we subtract 160 from 161, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 32 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 19955.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
32 can be fit into 100 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 19955.03
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
32 can be fit into 40 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 19955.031
If we subtract 32 from 40, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
32 goes into 80 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 19955.0312
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 32 fits into 160 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 19955.03125
Subtract 160 from 160 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
32 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19955.03125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
The number 32 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 19955.03125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 19955.03125, with a leftover of 0.0.
