We're dividing 42943589 by 208 
The aim is to understand the frequency of 208 in 42943589.

Step 1:
When dividing 4 by 208, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 208

Going ahead to step 2:
208 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 208

On to step 3:
When dividing 429 by 208, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 416 from 429 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 208

Step 4:
134 divided by 208 is 0 with a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 134 after subtracting 0 from 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 208

On to step 5:
When dividing 1343 by 208, we get 6 with a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
The remainder is 95 after subtracting 1248 from 1343.
Include the next digit (5) from the dividend after 95, then repeat: 955 / 208

Step 6:
208 can be fit into 955 4 times, resulting in a remainder of 123.
Write down 4 as next digit of the result. 
Result so far: 2064.0
If we take 832 away from 955, we end up with 123.
Append the next digit (8) from the dividend to 123 and continue with: 1238 / 208

Advancing to step 7:
1238 divided by 208 is 5 with a remainder of 198.
Record the quotient 5 as the next digit in the result. 
Result so far: 20645.0
Subtracting 1040 from 1238 leaves us with 198.
Include the next digit (9) from the dividend after 198, then repeat: 1989 / 208

Step 8:
When dividing 1989 by 208, we get 9 with a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 206459.0
If we take 1872 away from 1989, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
The number 208 fits into 1170 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 206459.5
Subtracting 1040 from 1170 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
If we divide 1300 by 208, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 206459.56
The remainder is 52 after subtracting 1248 from 1300.
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 11:
208 can be fit into 520 2 times, resulting in a remainder of 104.
The next digit of our result is 2. 
Result so far: 206459.562
The remainder is 104 after subtracting 416 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
208 goes into 1040 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 206459.5625
The remainder is 0 after subtracting 1040 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
The number 208 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 206459.5625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
The number 208 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 206459.5625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 206459.5625 and a remainder of 0.0.
