Let's divide 4364569 by 172
The aim is to understand the frequency of 172 in 4364569.

On to step 1:
The number 172 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 172

Moving on to step 2:
If we divide 43 by 172, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 172

Step 3:
The number 172 fits into 436 2 times, leaving a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 344 from 436 and we're left with 92.
Include the next digit (4) from the dividend after 92, then repeat: 924 / 172

Advancing to step 4:
172 can be fit into 924 5 times, resulting in a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 860 from 924 and we're left with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 172

Moving on to step 5:
The number 172 fits into 645 3 times, leaving a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
Subtract 516 from 645 to get 129.
Grab the next digit (6) from the dividend, add it to 129, then carry on: 1296 / 172

Advancing to step 6:
1296 divided by 172 is 7 with a remainder of 92.
Record the quotient 7 as the next digit in the result. 
Result so far: 2537.0
Subtract 1204 from 1296 to get 92.
Bring next digit (9) of the dividend behind the 92 and repeat the process: 929 / 172

Moving on to step 7:
172 goes into 929 5 times with a remainder of 69.
The next digit of our result is 5. 
Result so far: 25375.0
Subtracting 860 from 929 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 8:
If we divide 690 by 172, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 25375.4
Subtract 688 from 690 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
172 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 25375.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
172 goes into 200 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 25375.401
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 172 fits into 280 1 times, leaving a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 25375.4011
Subtracting 172 from 280 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 25375.4011, with a leftover of 0.00108.
