542720 divided by 81 
The aim is to understand the frequency of 81 in 542720.

Going ahead to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 81

Going ahead to step 2:
If we divide 54 by 81, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 81

Going ahead to step 3:
81 goes into 542 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 486 away from 542, we end up with 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 81

Advancing to step 4:
If we divide 567 by 81, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 567 from 567 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 81

Advancing to step 5:
81 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 81

Step 6:
When dividing 20 by 81, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 6700.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
When dividing 200 by 81, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 6700.2
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
81 can be fit into 380 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 6700.24
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
560 divided by 81 is 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 6700.246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
81 can be fit into 740 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 6700.2469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
81 can be fit into 110 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 6700.24691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
81 can be fit into 290 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 6700.246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 6700.2469135
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 6700.24691358
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 6700.24691358, and the remainder is 2e-09.
