Let's divide 487045 by 81
The aim is to understand the frequency of 81 in 487045.

Going ahead to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 81

Let's proceed to step 2:
When dividing 48 by 81, we get 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 81

Step 3:
If we divide 487 by 81, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 1 after subtracting 486 from 487.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 81

Going ahead to step 4:
81 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 10 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 81

Advancing to step 5:
If we divide 104 by 81, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 601.0
If we subtract 81 from 104, we get 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 81

Going ahead to step 6:
When dividing 235 by 81, we get 2 with a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 6012.0
If we take 162 away from 235, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
When dividing 730 by 81, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 6012.9
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
When dividing 10 by 81, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6012.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 6012.901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 6012.9012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 81 is 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 6012.90123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
If we divide 370 by 81, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 6012.901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
When dividing 460 by 81, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 6012.9012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 6012.90123456
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 6012.90123456, with a leftover of 6.4e-08.
