421591 divided by 32 
The aim is to understand the frequency of 32 in 421591.

On to step 1:
If we divide 4 by 32, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 32

Step 2:
32 goes into 42 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 32 away from 42, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 32

Going ahead to step 3:
The number 32 fits into 101 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 96 from 101, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 32

Moving on to step 4:
If we divide 55 by 32, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 32 from 55 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 32

Let's proceed to step 5:
32 goes into 239 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1317.0
Deduct 224 from 239 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 32

Moving on to step 6:
32 can be fit into 151 4 times, resulting in a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 13174.0
Subtracting 128 from 151 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 32 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 13174.7
Deduct 224 from 230 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 32, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 13174.71
Subtracting 32 from 60 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 32, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 13174.718
Subtracting 256 from 280 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 32, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 13174.7187
If we take 224 away from 240, we end up 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:
160 divided by 32 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13174.71875
The remainder is 0 after subtracting 160 from 160.
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 12:
32 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13174.71875
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.

Going ahead to step 13:
When dividing 0 by 32, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13174.71875
Deduct 0 from 0 and we're left with 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 result is 13174.71875 with a remainder of 0.0.
