Let's divide 54154589 by 161
The aim is to understand the frequency of 161 in 54154589.

Let's proceed to step 1:
161 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 161

Moving on to step 2:
If we divide 54 by 161, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 161

On to step 3:
541 divided by 161 is 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 483 from 541 to get 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 161

Step 4:
If we divide 585 by 161, we get 3 and a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 483 from 585 to get 102.
Append the next digit (4) from the dividend to 102 and continue with: 1024 / 161

Step 5:
1024 divided by 161 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 336.0
If we subtract 966 from 1024, we get 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 161

Going ahead to step 6:
585 divided by 161 is 3 with a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 3363.0
Deduct 483 from 585 and we're left with 102.
Grab the next digit (8) from the dividend, add it to 102, then carry on: 1028 / 161

Moving on to step 7:
When dividing 1028 by 161, we get 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 33636.0
The remainder is 62 after subtracting 966 from 1028.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 161

Let's proceed to step 8:
629 divided by 161 is 3 with a remainder of 146.
The next digit of our result is 3. 
Result so far: 336363.0
Subtract 483 from 629 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
The number 161 fits into 1460 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 336363.9
Deduct 1449 from 1460 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
110 divided by 161 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 336363.9
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
161 goes into 1100 6 times with a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 336363.906
Deduct 966 from 1100 and we're left with 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 12:
161 goes into 1340 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 336363.9068
Deduct 1288 from 1340 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
The number 161 fits into 520 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 336363.90683
Subtract 483 from 520 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
161 can be fit into 370 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 336363.906832
Subtracting 322 from 370 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
161 goes into 480 2 times with a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 336363.9068322
Deduct 322 from 480 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final result is 336363.9068322 with a remainder of 1.58e-06.
