867050 divided by 81 
The aim is to understand the frequency of 81 in 867050.

Let's proceed to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

Advancing to step 2:
If we divide 86 by 81, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 86 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 81

Step 3:
When dividing 57 by 81, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 57 after subtracting 0 from 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 81

Step 4:
81 can be fit into 570 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtract 567 from 570 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 81

Step 5:
81 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 1070.0
The remainder is 35 after subtracting 0 from 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 81

Let's proceed to step 6:
81 goes into 350 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10704.0
If we take 324 away from 350, we end up 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.

On to step 7:
When dividing 260 by 81, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 10704.3
Deduct 243 from 260 and we're left 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.

Moving on to step 8:
170 divided by 81 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 10704.32
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.

On to step 9:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10704.32
Deduct 0 from 80 and we're left 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.

Going ahead to step 10:
When dividing 800 by 81, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 10704.3209
If we take 729 away from 800, we end up 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.

On to step 11:
If we divide 710 by 81, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 10704.32098
If we take 648 away from 710, we end up with 62.
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 12:
620 divided by 81 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 10704.320987
Subtracting 567 from 620 leaves us 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 13:
If we divide 530 by 81, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 10704.3209876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
81 can be fit into 440 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10704.32098765
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 10704.32098765 with a balance of 3.5e-08.
