16221257 ÷ 162 
The aim is to understand the frequency of 162 in 16221257.

Going ahead to step 1:
When dividing 1 by 162, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 162

Moving on to step 2:
162 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 162

On to step 3:
162 goes into 162 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 162 from 162 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 162

Moving on to step 4:
When dividing 2 by 162, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 162

Step 5:
The number 162 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 21, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 162

Going ahead to step 6:
The number 162 fits into 212 1 times, leaving a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1001.0
Deduct 162 from 212 and we're left with 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 162

On to step 7:
If we divide 505 by 162, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 10013.0
The remainder is 19 after subtracting 486 from 505.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 162

Advancing to step 8:
When dividing 197 by 162, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 100131.0
Subtract 162 from 197 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
162 can be fit into 350 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 100131.2
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 162, we get 1 with a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 100131.21
Subtracting 162 from 260 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
162 goes into 980 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 100131.216
Deduct 972 from 980 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 162 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 100131.216
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 162, we get 4 with a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 100131.21604
If we take 648 away from 800, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
1520 divided by 162 is 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 100131.216049
Deduct 1458 from 1520 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 15:
162 goes into 620 3 times with a remainder of 134.
Use 3 as the next digit of our solution. 
Result so far: 100131.2160493
If we subtract 486 from 620, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 16:
The number 162 fits into 1340 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 100131.21604938
If we take 1296 away from 1340, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 100131.21604938 with a remainder of 4.4e-08.
