Let's divide 15542568 by 187
The aim is to understand the frequency of 187 in 15542568.

On to step 1:
If we divide 1 by 187, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 187

Moving on to step 2:
187 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 187

On to step 3:
If we divide 155 by 187, we get 0 and a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Grab the next digit (4) from the dividend, add it to 155, then carry on: 1554 / 187

Step 4:
When dividing 1554 by 187, we get 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 1496 from 1554 leaves us with 58.
Bring next digit (2) of the dividend behind the 58 and repeat the process: 582 / 187

Let's proceed to step 5:
187 can be fit into 582 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 21 after subtracting 561 from 582.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 187

Let's proceed to step 6:
The number 187 fits into 215 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 831.0
Subtracting 187 from 215 leaves us with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 187

Moving on to step 7:
The number 187 fits into 286 1 times, leaving a remainder of 99.
The next digit of our result is 1. 
Result so far: 8311.0
Subtracting 187 from 286 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 187

Step 8:
If we divide 998 by 187, we get 5 and a remainder of 63.
The next digit of our result is 5. 
Result so far: 83115.0
Deduct 935 from 998 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
When dividing 630 by 187, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 83115.3
Deduct 561 from 630 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
690 divided by 187 is 3 with a remainder of 129.
The next digit of our result is 3. 
Result so far: 83115.33
Subtract 561 from 690 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 83115.33 with a remainder of 0.129.
