Let's divide 268846 by 81
The aim is to understand the frequency of 81 in 268846.

Moving on to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 81

On to step 2:
81 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 81

Going ahead to step 3:
If we divide 268 by 81, we get 3 and a remainder of 25.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 243 from 268 and we're left with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 81

Advancing to step 4:
When dividing 258 by 81, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 243 away from 258, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 81

Advancing to step 5:
154 divided by 81 is 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 331.0
If we subtract 81 from 154, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 81

Advancing to step 6:
736 divided by 81 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 3319.0
Subtract 729 from 736 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 81, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 3319.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 3319.08
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 81 is 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 3319.086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
81 goes into 340 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3319.0864
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 3319.08641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
When dividing 790 by 81, we get 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 3319.086419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 3319.0864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 3319.08641975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 3319.08641975, and the remainder is 2.5e-08.
