Let's divide 147149 by 81
The aim is to understand the frequency of 81 in 147149.

On to step 1:
81 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 81

Moving on to step 2:
If we divide 14 by 81, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 81

Advancing to step 3:
147 divided by 81 is 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 147, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 81

Moving on to step 4:
The number 81 fits into 661 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 13 after subtracting 648 from 661.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 81

Let's proceed to step 5:
81 goes into 134 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we take 81 away from 134, we end up with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 81

Moving on to step 6:
539 divided by 81 is 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 1816.0
If we take 486 away from 539, 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.

Going ahead to step 7:
530 divided by 81 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1816.6
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1816.65
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 81, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1816.654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
When dividing 260 by 81, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 1816.6543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
81 goes into 170 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1816.65432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
80 divided by 81 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1816.65432
Subtracting 0 from 80 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 13:
81 can be fit into 800 9 times, resulting in a remainder of 71.
The next digit of our result is 9. 
Result so far: 1816.6543209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 14:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 1816.65432098
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 1816.65432098 with a balance of 6.2e-08.
