We're dividing 372032 by 81 
The aim is to understand the frequency of 81 in 372032.

Going ahead to step 1:
81 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 81

Advancing to step 2:
When dividing 37 by 81, we get 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 81

Going ahead to step 3:
81 goes into 372 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 48 after subtracting 324 from 372.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 81

Going ahead to step 4:
If we divide 480 by 81, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 405 from 480 leaves us with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 81

Let's proceed to step 5:
81 goes into 753 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 459.0
Deduct 729 from 753 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 81

Moving on to step 6:
When dividing 242 by 81, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 4592.0
Subtracting 162 from 242 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 7:
81 goes into 800 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 4592.9
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 8:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 4592.98
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
81 goes into 620 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 4592.987
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4592.9876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
81 goes into 440 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4592.98765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
350 divided by 81 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4592.987654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
81 goes into 260 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 4592.9876543
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
170 divided by 81 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4592.98765432
If we subtract 162 from 170, 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.

The final outcome is 4592.98765432, with a leftover of 8e-09.
