We look at the division of 10255755 by 172 
The aim is to understand the frequency of 172 in 10255755.

Going ahead to step 1:
If we divide 1 by 172, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 172

On to step 2:
The number 172 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 172

Advancing to step 3:
172 goes into 102 0 times with a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 102 to get 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 172

On to step 4:
1025 divided by 172 is 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 860 away from 1025, we end up with 165.
Bring next digit (5) of the dividend behind the 165 and repeat the process: 1655 / 172

On to step 5:
1655 divided by 172 is 9 with a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 1548 from 1655 leaves us with 107.
Bring next digit (7) of the dividend behind the 107 and repeat the process: 1077 / 172

Let's proceed to step 6:
The number 172 fits into 1077 6 times, leaving a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 596.0
Subtracting 1032 from 1077 leaves us with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 172

Moving on to step 7:
When dividing 455 by 172, we get 2 with a remainder of 111.
The number 2 becomes the next digit in our result. 
Result so far: 5962.0
Deduct 344 from 455 and we're left with 111.
Bring next digit (5) of the dividend behind the 111 and repeat the process: 1115 / 172

On to step 8:
1115 divided by 172 is 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 59626.0
If we subtract 1032 from 1115, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 9:
830 divided by 172 is 4 with a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 59626.4
The remainder is 142 after subtracting 688 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
1420 divided by 172 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 59626.48
If we take 1376 away from 1420, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
172 goes into 440 2 times with a remainder of 96.
The next digit of our result is 2. 
Result so far: 59626.482
Subtract 344 from 440 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
172 goes into 960 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 59626.4825
If we subtract 860 from 960, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
The number 172 fits into 1000 5 times, leaving a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 59626.48255
If we take 860 away from 1000, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 59626.48255 and a remainder of 0.00014.
