61715552 divided by 171 
The aim is to understand the frequency of 171 in 61715552.

Going ahead to step 1:
171 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 171

Step 2:
The number 171 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 171

Step 3:
171 can be fit into 617 3 times, resulting in a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 513 away from 617, we end up with 104.
Include the next digit (1) from the dividend after 104, then repeat: 1041 / 171

On to step 4:
171 goes into 1041 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 15 after subtracting 1026 from 1041.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 171

Step 5:
The number 171 fits into 155 0 times, leaving a remainder of 155.
Write down 0 as next digit of the result. 
Result so far: 360.0
If we subtract 0 from 155, we get 155.
Grab the next digit (5) from the dividend, add it to 155, then carry on: 1555 / 171

Advancing to step 6:
171 goes into 1555 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 3609.0
If we subtract 1539 from 1555, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 171

Moving on to step 7:
171 can be fit into 165 0 times, resulting in a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 36090.0
If we take 0 away from 165, we end up with 165.
Include the next digit (2) from the dividend after 165, then repeat: 1652 / 171

Let's proceed to step 8:
171 goes into 1652 9 times with a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 360909.0
Subtracting 1539 from 1652 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
171 can be fit into 1130 6 times, resulting in a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 360909.6
The remainder is 104 after subtracting 1026 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 10:
The number 171 fits into 1040 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 360909.66
Subtract 1026 from 1040 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 360909.66 and a remainder of 0.014.
