We're dividing 42429993 by 208 
The aim is to understand the frequency of 208 in 42429993.

Advancing to step 1:
208 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 208

On to step 2:
42 divided by 208 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 208

Let's proceed to step 3:
208 goes into 424 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 416 from 424, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 208

On to step 4:
208 goes into 82 0 times with a remainder of 82.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 82 to get 82.
Bring next digit (9) of the dividend behind the 82 and repeat the process: 829 / 208

Going ahead to step 5:
208 can be fit into 829 3 times, resulting in a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 203.0
Deduct 624 from 829 and we're left with 205.
Fetch the next digit (9) from the dividend, attach it to 205 and continue: 2059 / 208

Let's proceed to step 6:
208 can be fit into 2059 9 times, resulting in a remainder of 187.
The next digit of our result is 9. 
Result so far: 2039.0
If we take 1872 away from 2059, we end up with 187.
Fetch the next digit (9) from the dividend, attach it to 187 and continue: 1879 / 208

Moving on to step 7:
When dividing 1879 by 208, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 20399.0
Subtracting 1872 from 1879 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 208

Step 8:
73 divided by 208 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 203990.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
The number 208 fits into 730 3 times, leaving a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 203990.3
Subtract 624 from 730 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 10:
1060 divided by 208 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 203990.35
Subtracting 1040 from 1060 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
208 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 203990.35
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
If we divide 2000 by 208, we get 9 and a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 203990.3509
Subtracting 1872 from 2000 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
If we divide 1280 by 208, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 203990.35096
If we take 1248 away from 1280, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 208, we get 1 and a remainder of 112.
Put 1 as the next digit of the answer. 
Result so far: 203990.350961
Subtract 208 from 320 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
When dividing 1120 by 208, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 203990.3509615
Subtracting 1040 from 1120 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
When dividing 800 by 208, we get 3 with a remainder of 176.
Put 3 as the next digit of the answer. 
Result so far: 203990.35096153
If we subtract 624 from 800, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 203990.35096153 with a remainder of 1.76e-07.
