We look at the division of 57173675 by 273 
The aim is to understand the frequency of 273 in 57173675.

On to step 1:
The number 273 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 273

Step 2:
If we divide 57 by 273, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 273

On to step 3:
273 can be fit into 571 2 times, resulting in a remainder of 25.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 546 from 571, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 273

Advancing to step 4:
When dividing 257 by 273, we get 0 with a remainder of 257.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 257, we get 257.
Bring next digit (3) of the dividend behind the 257 and repeat the process: 2573 / 273

Going ahead to step 5:
273 goes into 2573 9 times with a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Deduct 2457 from 2573 and we're left with 116.
Append the next digit (6) from the dividend to 116 and continue with: 1166 / 273

On to step 6:
1166 divided by 273 is 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 2094.0
If we take 1092 away from 1166, we end up with 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 273

Advancing to step 7:
273 can be fit into 747 2 times, resulting in a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 20942.0
If we take 546 away from 747, we end up with 201.
Append the next digit (5) from the dividend to 201 and continue with: 2015 / 273

Let's proceed to step 8:
The number 273 fits into 2015 7 times, leaving a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 209427.0
The remainder is 104 after subtracting 1911 from 2015.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
When dividing 1040 by 273, we get 3 with a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 209427.3
Deduct 819 from 1040 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 10:
When dividing 2210 by 273, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 209427.38
Deduct 2184 from 2210 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
When dividing 260 by 273, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 209427.38
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
273 can be fit into 2600 9 times, resulting in a remainder of 143.
Use 9 as the next digit of our solution. 
Result so far: 209427.3809
The remainder is 143 after subtracting 2457 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 13:
When dividing 1430 by 273, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 209427.38095
Subtracting 1365 from 1430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
The number 273 fits into 650 2 times, leaving a remainder of 104.
The next digit of our result is 2. 
Result so far: 209427.380952
Subtracting 546 from 650 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 15:
The number 273 fits into 1040 3 times, leaving a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 209427.3809523
Deduct 819 from 1040 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 16:
273 can be fit into 2210 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 209427.38095238
The remainder is 26 after subtracting 2184 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 209427.38095238 and a remainder of 2.6e-08.
