We're dividing 994776 by 81 
The aim is to understand the frequency of 81 in 994776.

Advancing to step 1:
81 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 81

Let's proceed to step 2:
99 divided by 81 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 81 from 99 leaves us with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 81

On to step 3:
81 can be fit into 184 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 162 from 184, we get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 81

Let's proceed to step 4:
If we divide 227 by 81, we get 2 and a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtracting 162 from 227 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 81

Let's proceed to step 5:
81 can be fit into 657 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 1228.0
Subtract 648 from 657 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 81

On to step 6:
81 can be fit into 96 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 12281.0
If we take 81 away from 96, we end up 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.

Let's proceed to step 7:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 12281.1
Subtract 81 from 150 to 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.

Step 8:
690 divided by 81 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 12281.18
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.

Moving on to step 9:
420 divided by 81 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12281.185
If we take 405 away from 420, we end up 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.

Advancing to step 10:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 12281.1851
Subtract 81 from 150 to 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.

Going ahead to step 11:
When dividing 690 by 81, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 12281.18518
If we subtract 648 from 690, we 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.

Going ahead to step 12:
The number 81 fits into 420 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12281.185185
If we subtract 405 from 420, we get 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 13:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 12281.1851851
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 14:
81 can be fit into 690 8 times, resulting in a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 12281.18518518
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.

The final outcome is 12281.18518518, with a leftover of 4.2e-08.
