We're dividing 179661 by 81 
The aim is to understand the frequency of 81 in 179661.

Going ahead to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 81

On to step 2:
17 divided by 81 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 81

Let's proceed to step 3:
81 goes into 179 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 162 from 179 leaves us with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 81

Step 4:
81 goes into 176 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 162 from 176, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 81

Going ahead to step 5:
The number 81 fits into 146 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 221.0
Deduct 81 from 146 and we're left with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 81

Let's proceed to step 6:
If we divide 651 by 81, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 2218.0
If we take 648 away from 651, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2218.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 81 is 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 2218.03
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
The number 81 fits into 570 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 2218.037
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2218.037
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
300 divided by 81 is 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 2218.03703
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
If we divide 570 by 81, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2218.037037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2218.037037
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
300 divided by 81 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 2218.03703703
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 2218.03703703 with a balance of 5.7e-08.
