65476524 ÷ 161 
The aim is to understand the frequency of 161 in 65476524.

Moving on to step 1:
161 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 161

Step 2:
When dividing 65 by 161, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 161

Advancing to step 3:
654 divided by 161 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 644 from 654, we get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 161

On to step 4:
When dividing 107 by 161, we get 0 with a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 107 after subtracting 0 from 107.
Append the next digit (6) from the dividend to 107 and continue with: 1076 / 161

Going ahead to step 5:
161 goes into 1076 6 times with a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 406.0
Subtract 966 from 1076 to get 110.
Include the next digit (5) from the dividend after 110, then repeat: 1105 / 161

On to step 6:
When dividing 1105 by 161, we get 6 with a remainder of 139.
Write down 6 as next digit of the result. 
Result so far: 4066.0
If we take 966 away from 1105, we end up with 139.
Grab the next digit (2) from the dividend, add it to 139, then carry on: 1392 / 161

Let's proceed to step 7:
161 goes into 1392 8 times with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 40668.0
Deduct 1288 from 1392 and we're left with 104.
Include the next digit (4) from the dividend after 104, then repeat: 1044 / 161

Going ahead to step 8:
161 can be fit into 1044 6 times, resulting in a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 406686.0
The remainder is 78 after subtracting 966 from 1044.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
If we divide 780 by 161, we get 4 and a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 406686.4
If we subtract 644 from 780, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
The number 161 fits into 1360 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 406686.48
The remainder is 72 after subtracting 1288 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
161 goes into 720 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 406686.484
If we subtract 644 from 720, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
If we divide 760 by 161, we get 4 and a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 406686.4844
Subtract 644 from 760 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 406686.4844 and a remainder of 0.00116.
