We're dividing 81872860 by 32 
The aim is to understand the frequency of 32 in 81872860.

Moving on to step 1:
The number 32 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 32

Advancing to step 2:
When dividing 81 by 32, we get 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 64 from 81 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 32

Step 3:
32 goes into 178 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 160 from 178 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 32

Moving on to step 4:
32 goes into 187 5 times with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Subtracting 160 from 187 leaves us with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 32

On to step 5:
The number 32 fits into 272 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2558.0
Subtracting 256 from 272 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 32

Let's proceed to step 6:
When dividing 168 by 32, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 25585.0
If we take 160 away from 168, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 32

Step 7:
32 goes into 86 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 255852.0
Deduct 64 from 86 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 32

Let's proceed to step 8:
When dividing 220 by 32, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 2558526.0
Subtract 192 from 220 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
The number 32 fits into 280 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 2558526.8
Deduct 256 from 280 and we're left 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.

On to step 10:
32 can be fit into 240 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 2558526.87
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 32, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2558526.875
Deduct 160 from 160 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.

Let's proceed to step 12:
If we divide 0 by 32, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2558526.875
If we take 0 away from 0, we end up 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.

Going ahead to step 13:
If we divide 0 by 32, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2558526.875
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.

After the division, we end up with 2558526.875 and a remainder of 0.0.
