We're dividing 25546844 by 161 
The aim is to understand the frequency of 161 in 25546844.

Moving on to step 1:
The number 161 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 161

Moving on to step 2:
25 divided by 161 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 161

On to step 3:
161 goes into 255 1 times with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 161 from 255 leaves us with 94.
Take the next digit (4) from the dividend and append it to 94, then repeat: 944 / 161

On to step 4:
The number 161 fits into 944 5 times, leaving a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 805 from 944 and we're left with 139.
Include the next digit (6) from the dividend after 139, then repeat: 1396 / 161

Let's proceed to step 5:
If we divide 1396 by 161, we get 8 and a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we subtract 1288 from 1396, we get 108.
Append the next digit (8) from the dividend to 108 and continue with: 1088 / 161

On to step 6:
161 can be fit into 1088 6 times, resulting in a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 1586.0
The remainder is 122 after subtracting 966 from 1088.
Include the next digit (4) from the dividend after 122, then repeat: 1224 / 161

Moving on to step 7:
1224 divided by 161 is 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 15867.0
The remainder is 97 after subtracting 1127 from 1224.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 161

Let's proceed to step 8:
161 goes into 974 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 158676.0
The remainder is 8 after subtracting 966 from 974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
161 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 158676.0
Deduct 0 from 80 and we're left 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.

Going ahead to step 10:
The number 161 fits into 800 4 times, leaving a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 158676.04
If we subtract 644 from 800, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
1560 divided by 161 is 9 with a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 158676.049
If we subtract 1449 from 1560, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 12:
If we divide 1110 by 161, we get 6 and a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 158676.0496
If we take 966 away from 1110, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
1440 divided by 161 is 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 158676.04968
If we take 1288 away from 1440, 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.

Advancing to step 14:
161 goes into 1520 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 158676.049689
Subtract 1449 from 1520 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 15:
161 can be fit into 710 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 158676.0496894
The remainder is 66 after subtracting 644 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 16:
When dividing 660 by 161, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 158676.04968944
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 158676.04968944 with a remainder of 1.6e-08.
