81308450 ÷ 163 
The aim is to understand the frequency of 163 in 81308450.

Moving on to step 1:
163 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 163

Step 2:
81 divided by 163 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 163

Advancing to step 3:
163 can be fit into 813 4 times, resulting in a remainder of 161.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 652 from 813, we get 161.
Bring next digit (0) of the dividend behind the 161 and repeat the process: 1610 / 163

Advancing to step 4:
1610 divided by 163 is 9 with a remainder of 143.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we take 1467 away from 1610, we end up with 143.
Fetch the next digit (8) from the dividend, attach it to 143 and continue: 1438 / 163

Step 5:
163 can be fit into 1438 8 times, resulting in a remainder of 134.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
If we take 1304 away from 1438, we end up with 134.
Take the next digit (4) from the dividend and append it to 134, then repeat: 1344 / 163

Advancing to step 6:
1344 divided by 163 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4988.0
The remainder is 40 after subtracting 1304 from 1344.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 163

Going ahead to step 7:
If we divide 405 by 163, we get 2 and a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 49882.0
If we subtract 326 from 405, we get 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 163

Advancing to step 8:
163 goes into 790 4 times with a remainder of 138.
The next digit of our result is 4. 
Result so far: 498824.0
Subtracting 652 from 790 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
163 goes into 1380 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 498824.8
Subtract 1304 from 1380 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
When dividing 760 by 163, we get 4 with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 498824.84
Deduct 652 from 760 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
163 goes into 1080 6 times with a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 498824.846
Subtract 978 from 1080 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
163 can be fit into 1020 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 498824.8466
If we subtract 978 from 1020, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 498824.8466 with a remaining 0.00042.
