We divide 132298 by 81
The aim is to understand the frequency of 81 in 132298.

Step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 81

Step 2:
If we divide 13 by 81, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 81

Let's proceed to step 3:
81 goes into 132 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 81 from 132 and we're left with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 81

Step 4:
81 goes into 512 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 486 from 512, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 81

Going ahead to step 5:
If we divide 269 by 81, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 163.0
Deduct 243 from 269 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 81

On to step 6:
268 divided by 81 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 1633.0
If we subtract 243 from 268, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1633.3
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1633.3
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
700 divided by 81 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1633.308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 81, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 1633.3086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
81 goes into 340 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1633.30864
Subtract 324 from 340 to 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.

On to step 12:
When dividing 160 by 81, we get 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1633.308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 13:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 1633.3086419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 1633.30864197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 1633.30864197 and a remainder of 4.3e-08.
