We divide 860232 by 81
The aim is to understand the frequency of 81 in 860232.

On to step 1:
8 divided by 81 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 81

Let's proceed to step 2:
When dividing 86 by 81, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 86, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 81

Let's proceed to step 3:
When dividing 50 by 81, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 81

Advancing to step 4:
The number 81 fits into 502 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Deduct 486 from 502 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 81

Going ahead to step 5:
If we divide 163 by 81, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1062.0
If we subtract 162 from 163, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 81

Advancing to step 6:
81 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 10620.0
Deduct 0 from 12 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
81 goes into 120 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 10620.1
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
When dividing 390 by 81, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 10620.14
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
The number 81 fits into 660 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 10620.148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 81 fits into 120 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 10620.1481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
If we divide 390 by 81, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 10620.14814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
81 goes into 660 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 10620.148148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
When dividing 120 by 81, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 10620.1481481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
If we divide 390 by 81, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 10620.14814814
Subtracting 324 from 390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 10620.14814814 and a remainder of 6.6e-08.
