We're dividing 1815642 by 188 
The aim is to understand the frequency of 188 in 1815642.

Step 1:
188 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 188

Going ahead to step 2:
188 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 188

On to step 3:
188 goes into 181 0 times with a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 181 and we're left with 181.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 188

On to step 4:
188 can be fit into 1815 9 times, resulting in a remainder of 123.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 123 after subtracting 1692 from 1815.
Grab the next digit (6) from the dividend, add it to 123, then carry on: 1236 / 188

Going ahead to step 5:
188 goes into 1236 6 times with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 1128 from 1236 to get 108.
Take the next digit (4) from the dividend and append it to 108, then repeat: 1084 / 188

On to step 6:
188 goes into 1084 5 times with a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 965.0
If we subtract 940 from 1084, we get 144.
Take the next digit (2) from the dividend and append it to 144, then repeat: 1442 / 188

On to step 7:
1442 divided by 188 is 7 with a remainder of 126.
The next digit of our result is 7. 
Result so far: 9657.0
If we subtract 1316 from 1442, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 8:
The number 188 fits into 1260 6 times, leaving a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 9657.6
If we subtract 1128 from 1260, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
188 goes into 1320 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 9657.67
If we subtract 1316 from 1320, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
When dividing 40 by 188, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9657.67
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
188 can be fit into 400 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9657.6702
If we subtract 376 from 400, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 188, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 9657.67021
If we subtract 188 from 240, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
If we divide 520 by 188, we get 2 and a remainder of 144.
The next digit of our result is 2. 
Result so far: 9657.670212
Subtracting 376 from 520 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
188 goes into 1440 7 times with a remainder of 124.
The next digit of our result is 7. 
Result so far: 9657.6702127
Subtracting 1316 from 1440 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 15:
If we divide 1240 by 188, we get 6 and a remainder of 112.
The next digit of our result is 6. 
Result so far: 9657.67021276
If we take 1128 away from 1240, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 9657.67021276 with a remainder of 1.12e-07.
