33143202 ÷ 161 
The aim is to understand the frequency of 161 in 33143202.

Moving on to step 1:
161 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 161

Let's proceed to step 2:
33 divided by 161 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 161

Going ahead to step 3:
161 can be fit into 331 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 322 from 331, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 161

Step 4:
161 can be fit into 94 0 times, resulting in a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 94 after subtracting 0 from 94.
Include the next digit (3) from the dividend after 94, then repeat: 943 / 161

Moving on to step 5:
943 divided by 161 is 5 with a remainder of 138.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we subtract 805 from 943, we get 138.
Include the next digit (2) from the dividend after 138, then repeat: 1382 / 161

Moving on to step 6:
The number 161 fits into 1382 8 times, leaving a remainder of 94.
The next digit of our result is 8. 
Result so far: 2058.0
Subtracting 1288 from 1382 leaves us with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 161

On to step 7:
When dividing 940 by 161, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 20585.0
If we take 805 away from 940, we end up with 135.
Fetch the next digit (2) from the dividend, attach it to 135 and continue: 1352 / 161

Let's proceed to step 8:
If we divide 1352 by 161, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 205858.0
Subtract 1288 from 1352 to get 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 9:
640 divided by 161 is 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 205858.3
Deduct 483 from 640 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 10:
When dividing 1570 by 161, we get 9 with a remainder of 121.
Record the quotient 9 as the next digit in the result. 
Result so far: 205858.39
The remainder is 121 after subtracting 1449 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 11:
When dividing 1210 by 161, we get 7 with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 205858.397
If we subtract 1127 from 1210, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
830 divided by 161 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 205858.3975
Deduct 805 from 830 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.

Step 13:
The number 161 fits into 250 1 times, leaving a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 205858.39751
Deduct 161 from 250 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
If we divide 890 by 161, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 205858.397515
Deduct 805 from 890 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
The number 161 fits into 850 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 205858.3975155
Subtracting 805 from 850 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 205858.3975155 with a remaining 4.5e-07.
