We're dividing 38894290 by 161 
The aim is to understand the frequency of 161 in 38894290.

Step 1:
3 divided by 161 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 161

Let's proceed to step 2:
161 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 161

Advancing to step 3:
388 divided by 161 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 322 from 388 and we're left with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 161

Moving on to step 4:
If we divide 669 by 161, we get 4 and a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 644 away from 669, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 161

Step 5:
161 can be fit into 254 1 times, resulting in a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtracting 161 from 254 leaves us with 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 161

Let's proceed to step 6:
If we divide 932 by 161, we get 5 and a remainder of 127.
The next digit of our result is 5. 
Result so far: 2415.0
The remainder is 127 after subtracting 805 from 932.
Take the next digit (9) from the dividend and append it to 127, then repeat: 1279 / 161

On to step 7:
The number 161 fits into 1279 7 times, leaving a remainder of 152.
The next digit of our result is 7. 
Result so far: 24157.0
If we subtract 1127 from 1279, we get 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 161

Let's proceed to step 8:
When dividing 1520 by 161, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 241579.0
Subtracting 1449 from 1520 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
710 divided by 161 is 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 241579.4
Subtracting 644 from 710 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
161 goes into 660 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 241579.44
Subtract 644 from 660 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 241579.44 with a remainder of 0.016.
