We're dividing 25475685 by 173 
The aim is to understand the frequency of 173 in 25475685.

Let's proceed to step 1:
2 divided by 173 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 173

Step 2:
173 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 173

On to step 3:
254 divided by 173 is 1 with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 173 from 254 to get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 173

Going ahead to step 4:
173 goes into 817 4 times with a remainder of 125.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 692 from 817 to get 125.
Bring next digit (5) of the dividend behind the 125 and repeat the process: 1255 / 173

Advancing to step 5:
1255 divided by 173 is 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtracting 1211 from 1255 leaves us with 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 173

Going ahead to step 6:
173 can be fit into 446 2 times, resulting in a remainder of 100.
The next digit of our result is 2. 
Result so far: 1472.0
If we subtract 346 from 446, we get 100.
Take the next digit (8) from the dividend and append it to 100, then repeat: 1008 / 173

Let's proceed to step 7:
173 can be fit into 1008 5 times, resulting in a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 14725.0
Subtracting 865 from 1008 leaves us with 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 173

On to step 8:
1435 divided by 173 is 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 147258.0
Deduct 1384 from 1435 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
173 goes into 510 2 times with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 147258.2
If we take 346 away from 510, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
When dividing 1640 by 173, we get 9 with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 147258.29
The remainder is 83 after subtracting 1557 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 11:
The number 173 fits into 830 4 times, leaving a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 147258.294
Deduct 692 from 830 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 12:
173 goes into 1380 7 times with a remainder of 169.
The next digit of our result is 7. 
Result so far: 147258.2947
The remainder is 169 after subtracting 1211 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 13:
173 goes into 1690 9 times with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 147258.29479
Deduct 1557 from 1690 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 14:
If we divide 1330 by 173, we get 7 and a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 147258.294797
Subtract 1211 from 1330 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 15:
173 goes into 1190 6 times with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 147258.2947976
Deduct 1038 from 1190 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 16:
The number 173 fits into 1520 8 times, leaving a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 147258.29479768
If we subtract 1384 from 1520, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

In conclusion, the division gives 147258.29479768 with a balance of 1.36e-07.
