We're dividing 20732661 by 673 
The aim is to understand the frequency of 673 in 20732661.

Going ahead to step 1:
If we divide 2 by 673, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 673

Step 2:
When dividing 20 by 673, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 673

Moving on to step 3:
207 divided by 673 is 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 207 leaves us with 207.
Take the next digit (3) from the dividend and append it to 207, then repeat: 2073 / 673

Going ahead to step 4:
673 can be fit into 2073 3 times, resulting in a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2019 from 2073 to get 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 673

Let's proceed to step 5:
673 goes into 542 0 times with a remainder of 542.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 542 and we're left with 542.
Fetch the next digit (6) from the dividend, attach it to 542 and continue: 5426 / 673

Let's proceed to step 6:
The number 673 fits into 5426 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 308.0
The remainder is 42 after subtracting 5384 from 5426.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 673

Moving on to step 7:
When dividing 426 by 673, we get 0 with a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 3080.0
Subtracting 0 from 426 leaves us with 426.
Grab the next digit (1) from the dividend, add it to 426, then carry on: 4261 / 673

Let's proceed to step 8:
If we divide 4261 by 673, we get 6 and a remainder of 223.
Put 6 as the next digit of the answer. 
Result so far: 30806.0
If we take 4038 away from 4261, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 9:
673 goes into 2230 3 times with a remainder of 211.
The next digit of our result is 3. 
Result so far: 30806.3
Deduct 2019 from 2230 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 10:
2110 divided by 673 is 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 30806.33
Subtract 2019 from 2110 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final outcome is 30806.33, with a leftover of 0.091.
