Let's divide 4805425 by 81
The aim is to understand the frequency of 81 in 4805425.

Going ahead to step 1:
81 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 81

Let's proceed to step 2:
The number 81 fits into 48 0 times, leaving a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 81

Going ahead to step 3:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 75 after subtracting 405 from 480.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 81

Let's proceed to step 4:
If we divide 755 by 81, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 729 from 755 to get 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 81

Moving on to step 5:
When dividing 264 by 81, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 593.0
Deduct 243 from 264 and we're left with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 81

Let's proceed to step 6:
When dividing 212 by 81, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 5932.0
Deduct 162 from 212 and we're left with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 81

Step 7:
The number 81 fits into 505 6 times, leaving a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 59326.0
The remainder is 19 after subtracting 486 from 505.
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 8:
190 divided by 81 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 59326.2
Subtract 162 from 190 to 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.

Going ahead to step 9:
81 can be fit into 280 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 59326.23
If we subtract 243 from 280, we get 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 10:
81 goes into 370 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 59326.234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 59326.2345
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
81 goes into 550 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 59326.23456
If we take 486 away from 550, we end up 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.

Going ahead to step 13:
81 can be fit into 640 7 times, resulting in a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 59326.234567
Deduct 567 from 640 and we're left 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.

Let's proceed to step 14:
81 goes into 730 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 59326.2345679
If we subtract 729 from 730, we 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.

Advancing to step 15:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 59326.2345679
If we take 0 away from 10, we end up 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.

The final outcome is 59326.2345679, with a leftover of 1e-08.
