766554 divided by 81 
The aim is to understand the frequency of 81 in 766554.

Going ahead to step 1:
81 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 81

Let's proceed to step 2:
81 goes into 76 0 times with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 81

Going ahead to step 3:
766 divided by 81 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 729 from 766 and we're left with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 81

Step 4:
When dividing 375 by 81, we get 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 324 from 375 and we're left with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 81

Going ahead to step 5:
If we divide 515 by 81, we get 6 and a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 946.0
The remainder is 29 after subtracting 486 from 515.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 81

On to step 6:
If we divide 294 by 81, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 9463.0
Subtracting 243 from 294 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
510 divided by 81 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9463.6
Subtracting 486 from 510 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
81 goes into 240 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 9463.62
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 81, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9463.629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
81 can be fit into 510 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 9463.6296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
The number 81 fits into 240 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 9463.62962
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
81 can be fit into 780 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9463.629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 9463.6296296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
If we divide 240 by 81, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 9463.62962962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 9463.62962962 with a balance of 7.8e-08.
