Let's divide 950098 by 81
The aim is to understand the frequency of 81 in 950098.

Going ahead to step 1:
81 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 81

Advancing to step 2:
When dividing 95 by 81, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 95 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 81

Going ahead to step 3:
81 can be fit into 140 1 times, resulting in a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 81 from 140, we get 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 81

Step 4:
If we divide 590 by 81, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 567 away from 590, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 81

Going ahead to step 5:
239 divided by 81 is 2 with a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 1172.0
If we subtract 162 from 239, we get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 81

Going ahead to step 6:
81 can be fit into 778 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 11729.0
The remainder is 49 after subtracting 729 from 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11729.6
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 81, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11729.6
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 81 fits into 400 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 11729.604
Subtracting 324 from 400 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 81 fits into 760 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 11729.6049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
When dividing 310 by 81, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 11729.60493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 12:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 11729.604938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
When dividing 220 by 81, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 11729.6049382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
If we divide 580 by 81, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 11729.60493827
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 11729.60493827 and a remainder of 1.3e-08.
