We divide 127070 by 81
The aim is to understand the frequency of 81 in 127070.

Advancing to step 1:
1 divided by 81 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 81

Let's proceed to step 2:
The number 81 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 81

Going ahead to step 3:
81 goes into 127 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 127, we end up with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 81

Going ahead to step 4:
When dividing 460 by 81, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 405 from 460 to get 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 81

Step 5:
81 goes into 557 6 times with a remainder of 71.
The next digit of our result is 6. 
Result so far: 156.0
The remainder is 71 after subtracting 486 from 557.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 81

Step 6:
81 goes into 710 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 1568.0
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
81 goes into 620 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 1568.7
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.

Moving on to step 8:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1568.76
Deduct 486 from 530 and we're left 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.

Advancing to step 9:
If we divide 440 by 81, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1568.765
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.

Going ahead to step 10:
350 divided by 81 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 1568.7654
Subtracting 324 from 350 leaves us 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 11:
81 goes into 260 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 1568.76543
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 12:
81 goes into 170 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1568.765432
Deduct 162 from 170 and we're left 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.

Step 13:
When dividing 80 by 81, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1568.765432
If we take 0 away from 80, we end up 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.

Let's proceed to step 14:
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: 1568.76543209
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.

After the division, we end up with 1568.76543209 and a remainder of 7.1e-08.
