We're dividing 527758 by 81 
The aim is to understand the frequency of 81 in 527758.

Going ahead to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 81

Going ahead to step 2:
The number 81 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 81

Step 3:
81 can be fit into 527 6 times, resulting in a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 486 from 527 and we're left with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 81

On to step 4:
81 goes into 417 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 65.0
The remainder is 12 after subtracting 405 from 417.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 81

Step 5:
When dividing 125 by 81, we get 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 651.0
If we take 81 away from 125, we end up with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 81

On to step 6:
81 can be fit into 448 5 times, resulting in a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 6515.0
The remainder is 43 after subtracting 405 from 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
If we divide 430 by 81, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6515.5
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
81 can be fit into 250 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 6515.53
If we take 243 away from 250, we end up 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.

Let's proceed to step 9:
81 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 6515.53
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
700 divided by 81 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 6515.5308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
If we divide 520 by 81, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6515.53086
Deduct 486 from 520 and we're left 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.

Let's proceed to step 12:
When dividing 340 by 81, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 6515.530864
If we subtract 324 from 340, we 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.

Moving on to step 13:
When dividing 160 by 81, we get 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 6515.5308641
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.

Let's proceed to step 14:
If we divide 790 by 81, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 6515.53086419
Subtracting 729 from 790 leaves us 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.

After the division, we end up with 6515.53086419 and a remainder of 6.1e-08.
