We look at the division of 53374300 by 172 
The aim is to understand the frequency of 172 in 53374300.

On to step 1:
The number 172 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 172

On to step 2:
The number 172 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 172

Let's proceed to step 3:
533 divided by 172 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 516 from 533 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 172

Going ahead to step 4:
When dividing 177 by 172, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 31.0
If we take 172 away from 177, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 172

Moving on to step 5:
172 goes into 54 0 times with a remainder of 54.
The next digit of our result is 0. 
Result so far: 310.0
If we subtract 0 from 54, we get 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 172

Let's proceed to step 6:
172 goes into 543 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 3103.0
Subtracting 516 from 543 leaves us with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 172

Going ahead to step 7:
The number 172 fits into 270 1 times, leaving a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 31031.0
Subtract 172 from 270 to get 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 172

On to step 8:
The number 172 fits into 980 5 times, leaving a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 310315.0
The remainder is 120 after subtracting 860 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
When dividing 1200 by 172, we get 6 with a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 310315.6
Subtracting 1032 from 1200 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
When dividing 1680 by 172, we get 9 with a remainder of 132.
The next digit of our result is 9. 
Result so far: 310315.69
Deduct 1548 from 1680 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
When dividing 1320 by 172, we get 7 with a remainder of 116.
Use 7 as the next digit of our solution. 
Result so far: 310315.697
Subtracting 1204 from 1320 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
If we divide 1160 by 172, we get 6 and a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 310315.6976
Subtracting 1032 from 1160 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
172 can be fit into 1280 7 times, resulting in a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 310315.69767
Subtract 1204 from 1280 to 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.

Advancing to step 14:
If we divide 760 by 172, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 310315.697674
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 15:
720 divided by 172 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 310315.6976744
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 310315.6976744 with a balance of 3.2e-07.
