Let's divide 945654 by 81
The aim is to understand the frequency of 81 in 945654.

Going ahead to step 1:
9 divided by 81 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 81

Going ahead to step 2:
When dividing 94 by 81, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 94, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 81

Let's proceed to step 3:
135 divided by 81 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 81 from 135 and we're left with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 81

Step 4:
If we divide 546 by 81, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtracting 486 from 546 leaves us with 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 81

Going ahead to step 5:
605 divided by 81 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1167.0
Subtracting 567 from 605 leaves us with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 81

Going ahead to step 6:
384 divided by 81 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 11674.0
If we subtract 324 from 384, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
600 divided by 81 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 11674.7
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
330 divided by 81 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11674.74
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
If we divide 60 by 81, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 11674.74
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
600 divided by 81 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 11674.7407
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
When dividing 330 by 81, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 11674.74074
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
When dividing 60 by 81, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11674.74074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
600 divided by 81 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 11674.7407407
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
330 divided by 81 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 11674.74074074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 11674.74074074 with a balance of 6e-09.
