Let's divide 526893 by 81
The aim is to understand the frequency of 81 in 526893.

Going ahead to step 1:
81 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 81

Step 2:
52 divided by 81 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 81

Step 3:
When dividing 526 by 81, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 486 from 526 leaves us with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 81

On to step 4:
81 goes into 408 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 405 from 408, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 81

Moving on to step 5:
When dividing 39 by 81, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 650.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 81

Step 6:
81 goes into 393 4 times with a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 6504.0
Subtracting 324 from 393 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
When dividing 690 by 81, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6504.8
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 81 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 6504.85
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 81 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 6504.851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
81 goes into 690 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 6504.8518
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
When dividing 420 by 81, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6504.85185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
If we divide 150 by 81, we get 1 and a remainder of 69.
The next digit of our result is 1. 
Result so far: 6504.851851
If we subtract 81 from 150, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
81 goes into 690 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6504.8518518
If we take 648 away from 690, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
When dividing 420 by 81, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6504.85185185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 6504.85185185 with a remaining 1.5e-08.
