We look at the division of 72672100 by 357 
The aim is to understand the frequency of 357 in 72672100.

Let's proceed to step 1:
7 divided by 357 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 357

Going ahead to step 2:
If we divide 72 by 357, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 357

Moving on to step 3:
When dividing 726 by 357, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 714 from 726, we get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 357

Going ahead to step 4:
If we divide 127 by 357, we get 0 and a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 127, we get 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 357

Going ahead to step 5:
357 goes into 1272 3 times with a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 203.0
Deduct 1071 from 1272 and we're left with 201.
Include the next digit (1) from the dividend after 201, then repeat: 2011 / 357

Advancing to step 6:
If we divide 2011 by 357, we get 5 and a remainder of 226.
The number 5 becomes the next digit in our result. 
Result so far: 2035.0
If we take 1785 away from 2011, we end up with 226.
Bring next digit (0) of the dividend behind the 226 and repeat the process: 2260 / 357

Advancing to step 7:
357 goes into 2260 6 times with a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 20356.0
Subtracting 2142 from 2260 leaves us with 118.
Fetch the next digit (0) from the dividend, attach it to 118 and continue: 1180 / 357

On to step 8:
357 goes into 1180 3 times with a remainder of 109.
The next digit of our result is 3. 
Result so far: 203563.0
Subtract 1071 from 1180 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
If we divide 1090 by 357, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 203563.3
If we subtract 1071 from 1090, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
357 can be fit into 190 0 times, resulting in a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 203563.3
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
When dividing 1900 by 357, we get 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 203563.305
The remainder is 115 after subtracting 1785 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
357 can be fit into 1150 3 times, resulting in a remainder of 79.
The next digit of our result is 3. 
Result so far: 203563.3053
If we take 1071 away from 1150, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 13:
The number 357 fits into 790 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 203563.30532
Subtract 714 from 790 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
If we divide 760 by 357, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 203563.305322
The remainder is 46 after subtracting 714 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 203563.305322, with a leftover of 4.6e-06.
