We're dividing 68004994 by 173 
The aim is to understand the frequency of 173 in 68004994.

Let's proceed to step 1:
The number 173 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 173

Moving on to step 2:
When dividing 68 by 173, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 173

Let's proceed to step 3:
173 can be fit into 680 3 times, resulting in a remainder of 161.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 519 away from 680, we end up with 161.
Bring next digit (0) of the dividend behind the 161 and repeat the process: 1610 / 173

On to step 4:
The number 173 fits into 1610 9 times, leaving a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 1557 from 1610 and we're left with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 173

Step 5:
The number 173 fits into 534 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Subtract 519 from 534 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 173

Step 6:
The number 173 fits into 159 0 times, leaving a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 3930.0
If we subtract 0 from 159, we get 159.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 173

Step 7:
1599 divided by 173 is 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 39309.0
Deduct 1557 from 1599 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 173

Step 8:
424 divided by 173 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 393092.0
If we subtract 346 from 424, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
173 can be fit into 780 4 times, resulting in a remainder of 88.
The next digit of our result is 4. 
Result so far: 393092.4
If we subtract 692 from 780, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
When dividing 880 by 173, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 393092.45
If we take 865 away from 880, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
173 goes into 150 0 times with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 393092.45
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
If we divide 1500 by 173, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 393092.4508
Subtract 1384 from 1500 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 13:
173 goes into 1160 6 times with a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 393092.45086
If we take 1038 away from 1160, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 14:
173 goes into 1220 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 393092.450867
Subtract 1211 from 1220 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 15:
The number 173 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 393092.450867
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
173 can be fit into 900 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 393092.45086705
If we subtract 865 from 900, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 393092.45086705, with a leftover of 3.5e-08.
