We're dividing 12454657 by 186 
The aim is to understand the frequency of 186 in 12454657.

Step 1:
186 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 186

Advancing to step 2:
186 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 186

Let's proceed to step 3:
186 can be fit into 124 0 times, resulting in a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Bring next digit (5) of the dividend behind the 124 and repeat the process: 1245 / 186

Moving on to step 4:
When dividing 1245 by 186, we get 6 with a remainder of 129.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 1116 from 1245 leaves us with 129.
Fetch the next digit (4) from the dividend, attach it to 129 and continue: 1294 / 186

Let's proceed to step 5:
If we divide 1294 by 186, we get 6 and a remainder of 178.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 1116 from 1294, we get 178.
Include the next digit (6) from the dividend after 178, then repeat: 1786 / 186

Step 6:
When dividing 1786 by 186, we get 9 with a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 669.0
Subtracting 1674 from 1786 leaves us with 112.
Fetch the next digit (5) from the dividend, attach it to 112 and continue: 1125 / 186

Moving on to step 7:
When dividing 1125 by 186, we get 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6696.0
Deduct 1116 from 1125 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 186

Advancing to step 8:
When dividing 97 by 186, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 66960.0
If we subtract 0 from 97, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
186 can be fit into 970 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 66960.5
If we subtract 930 from 970, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 186 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 66960.52
The remainder is 28 after subtracting 372 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 186, we get 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 66960.521
The remainder is 94 after subtracting 186 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
If we divide 940 by 186, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 66960.5215
The remainder is 10 after subtracting 930 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
100 divided by 186 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 66960.5215
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
When dividing 1000 by 186, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 66960.521505
If we subtract 930 from 1000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
If we divide 700 by 186, we get 3 and a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 66960.5215053
The remainder is 142 after subtracting 558 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 16:
When dividing 1420 by 186, we get 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 66960.52150537
Deduct 1302 from 1420 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

In conclusion, the division gives 66960.52150537 with a balance of 1.18e-07.
