We look at the division of 176496 by 81 
The aim is to understand the frequency of 81 in 176496.

Advancing to step 1:
81 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 81

On to step 2:
The number 81 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 81

On to step 3:
81 goes into 176 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 14 after subtracting 162 from 176.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 81

Step 4:
When dividing 144 by 81, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 81 away from 144, we end up with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 81

Advancing to step 5:
The number 81 fits into 639 7 times, leaving a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 217.0
Deduct 567 from 639 and we're left with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 81

On to step 6:
When dividing 726 by 81, we get 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 2178.0
If we take 648 away from 726, 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.

Going ahead to step 7:
81 goes into 780 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 2178.9
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
510 divided by 81 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2178.96
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
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: 2178.962
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.

Moving on to step 10:
If we divide 780 by 81, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 2178.9629
Subtract 729 from 780 to get 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 11:
510 divided by 81 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2178.96296
Subtract 486 from 510 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 81, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 2178.962962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
If we divide 780 by 81, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 2178.9629629
If we take 729 away from 780, we end up 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 14:
When dividing 510 by 81, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2178.96296296
Subtract 486 from 510 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 2178.96296296, and the remainder is 2.4e-08.
