We're dividing 54857833 by 173 
The aim is to understand the frequency of 173 in 54857833.

Advancing to step 1:
If we divide 5 by 173, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 173

Moving on to step 2:
173 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 173

Going ahead to step 3:
173 can be fit into 548 3 times, resulting in a remainder of 29.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 519 from 548, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 173

On to step 4:
The number 173 fits into 295 1 times, leaving a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 122 after subtracting 173 from 295.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 173

Advancing to step 5:
When dividing 1227 by 173, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 317.0
If we subtract 1211 from 1227, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 173

Advancing to step 6:
The number 173 fits into 168 0 times, leaving a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 3170.0
If we subtract 0 from 168, we get 168.
Grab the next digit (3) from the dividend, add it to 168, then carry on: 1683 / 173

Advancing to step 7:
When dividing 1683 by 173, we get 9 with a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 31709.0
If we take 1557 away from 1683, we end up with 126.
Include the next digit (3) from the dividend after 126, then repeat: 1263 / 173

Step 8:
If we divide 1263 by 173, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 317097.0
Deduct 1211 from 1263 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
173 can be fit into 520 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 317097.3
If we subtract 519 from 520, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 173, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 317097.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 173 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 317097.3
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 317097.3, with a leftover of 0.01.
