Let's divide 25157703 by 172
The aim is to understand the frequency of 172 in 25157703.

Let's proceed to step 1:
172 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 172

Going ahead to step 2:
25 divided by 172 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 172

On to step 3:
172 goes into 251 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 172 away from 251, we end up with 79.
Fetch the next digit (5) from the dividend, attach it to 79 and continue: 795 / 172

Going ahead to step 4:
172 goes into 795 4 times with a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 688 from 795 leaves us with 107.
Include the next digit (7) from the dividend after 107, then repeat: 1077 / 172

Advancing to step 5:
172 can be fit into 1077 6 times, resulting in a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 146.0
The remainder is 45 after subtracting 1032 from 1077.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 172

Going ahead to step 6:
When dividing 457 by 172, we get 2 with a remainder of 113.
Use 2 as the next digit of our solution. 
Result so far: 1462.0
Subtracting 344 from 457 leaves us with 113.
Grab the next digit (0) from the dividend, add it to 113, then carry on: 1130 / 172

Advancing to step 7:
When dividing 1130 by 172, we get 6 with a remainder of 98.
The next digit of our result is 6. 
Result so far: 14626.0
Subtract 1032 from 1130 to get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 172

Let's proceed to step 8:
When dividing 983 by 172, we get 5 with a remainder of 123.
Use 5 as the next digit of our solution. 
Result so far: 146265.0
Subtracting 860 from 983 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
If we divide 1230 by 172, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 146265.7
The remainder is 26 after subtracting 1204 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
260 divided by 172 is 1 with a remainder of 88.
The next digit of our result is 1. 
Result so far: 146265.71
The remainder is 88 after subtracting 172 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
880 divided by 172 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 146265.715
Subtract 860 from 880 to 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.

Advancing to step 12:
172 can be fit into 200 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 146265.7151
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
172 can be fit into 280 1 times, resulting in a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 146265.71511
Deduct 172 from 280 and we're left 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 146265.71511, with a leftover of 0.000108.
