We look at the division of 81499750 by 187 
The aim is to understand the frequency of 187 in 81499750.

Going ahead to step 1:
The number 187 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 187

On to step 2:
187 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 187

Advancing to step 3:
The number 187 fits into 814 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 66 after subtracting 748 from 814.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 187

Going ahead to step 4:
When dividing 669 by 187, we get 3 with a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 108 after subtracting 561 from 669.
Bring next digit (9) of the dividend behind the 108 and repeat the process: 1089 / 187

Moving on to step 5:
1089 divided by 187 is 5 with a remainder of 154.
The next digit of our result is 5. 
Result so far: 435.0
If we subtract 935 from 1089, we get 154.
Grab the next digit (7) from the dividend, add it to 154, then carry on: 1547 / 187

Let's proceed to step 6:
187 goes into 1547 8 times with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 4358.0
The remainder is 51 after subtracting 1496 from 1547.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 187

On to step 7:
515 divided by 187 is 2 with a remainder of 141.
Record the quotient 2 as the next digit in the result. 
Result so far: 43582.0
If we take 374 away from 515, we end up with 141.
Include the next digit (0) from the dividend after 141, then repeat: 1410 / 187

Step 8:
187 goes into 1410 7 times with a remainder of 101.
Write down 7 as next digit of the result. 
Result so far: 435827.0
The remainder is 101 after subtracting 1309 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
187 can be fit into 1010 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 435827.5
The remainder is 75 after subtracting 935 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
When dividing 750 by 187, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 435827.54
Deduct 748 from 750 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
If we divide 20 by 187, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 435827.54
If we subtract 0 from 20, we get 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 12:
187 can be fit into 200 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 435827.5401
Subtract 187 from 200 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
187 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 435827.5401
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
187 can be fit into 1300 6 times, resulting in a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 435827.540106
Deduct 1122 from 1300 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 15:
187 goes into 1780 9 times with a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 435827.5401069
Deduct 1683 from 1780 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 16:
When dividing 970 by 187, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 435827.54010695
If we take 935 away from 970, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 435827.54010695, and the remainder is 3.5e-08.
