We look at the division of 99405101 by 188 
The aim is to understand the frequency of 188 in 99405101.

Going ahead to step 1:
When dividing 9 by 188, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 188

Let's proceed to step 2:
99 divided by 188 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 188

Advancing to step 3:
188 can be fit into 994 5 times, resulting in a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 940 from 994, we get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 188

On to step 4:
The number 188 fits into 540 2 times, leaving a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 376 from 540, we get 164.
Include the next digit (5) from the dividend after 164, then repeat: 1645 / 188

On to step 5:
The number 188 fits into 1645 8 times, leaving a remainder of 141.
Write down 8 as next digit of the result. 
Result so far: 528.0
The remainder is 141 after subtracting 1504 from 1645.
Take the next digit (1) from the dividend and append it to 141, then repeat: 1411 / 188

Going ahead to step 6:
The number 188 fits into 1411 7 times, leaving a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 5287.0
The remainder is 95 after subtracting 1316 from 1411.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 188

Going ahead to step 7:
If we divide 950 by 188, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 52875.0
The remainder is 10 after subtracting 940 from 950.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 188

Advancing to step 8:
188 can be fit into 101 0 times, resulting in a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 528750.0
Subtract 0 from 101 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
1010 divided by 188 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 528750.5
The remainder is 70 after subtracting 940 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
188 can be fit into 700 3 times, resulting in a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 528750.53
The remainder is 136 after subtracting 564 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 11:
The number 188 fits into 1360 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 528750.537
The remainder is 44 after subtracting 1316 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
440 divided by 188 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 528750.5372
If we subtract 376 from 440, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 188 fits into 640 3 times, leaving a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 528750.53723
If we subtract 564 from 640, we 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:
When dividing 760 by 188, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 528750.537234
Subtracting 752 from 760 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
188 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 528750.537234
If we take 0 away from 80, we end up 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.

Going ahead to step 16:
188 can be fit into 800 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 528750.53723404
Subtracting 752 from 800 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 528750.53723404 and a remainder of 4.8e-08.
