Let's divide 552768 by 81
The aim is to understand the frequency of 81 in 552768.

Step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 81

Step 2:
81 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 81

Let's proceed to step 3:
81 goes into 552 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 486 from 552 leaves us with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 81

Moving on to step 4:
If we divide 667 by 81, we get 8 and a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we take 648 away from 667, we end up with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 81

Advancing to step 5:
81 goes into 196 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 682.0
If we take 162 away from 196, we end up with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 81

Let's proceed to step 6:
81 can be fit into 348 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 6824.0
If we subtract 324 from 348, 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.

On to step 7:
If we divide 240 by 81, we get 2 and a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 6824.2
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.

On to step 8:
81 can be fit into 780 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 6824.29
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.

Let's proceed to step 9:
510 divided by 81 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6824.296
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.

On to step 10:
240 divided by 81 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 6824.2962
If we subtract 162 from 240, we 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.

Going ahead to step 11:
If we divide 780 by 81, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 6824.29629
If we subtract 729 from 780, we 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 12:
When dividing 510 by 81, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6824.296296
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.

Step 13:
81 can be fit into 240 2 times, resulting in a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 6824.2962962
The remainder is 78 after subtracting 162 from 240.
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 14:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 6824.29629629
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.

The quotient of the division is 6824.29629629, and the remainder is 5.1e-08.
