12396597 divided by 186 
The aim is to understand the frequency of 186 in 12396597.

Let's proceed to step 1:
The number 186 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 186

Going ahead to step 2:
When dividing 12 by 186, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 186

Let's proceed to step 3:
When dividing 123 by 186, we get 0 with a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 186

Advancing to step 4:
186 can be fit into 1239 6 times, resulting in a remainder of 123.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 1116 from 1239 to get 123.
Include the next digit (6) from the dividend after 123, then repeat: 1236 / 186

Moving on to step 5:
If we divide 1236 by 186, we get 6 and a remainder of 120.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 1116 from 1236, we get 120.
Append the next digit (5) from the dividend to 120 and continue with: 1205 / 186

Moving on to step 6:
When dividing 1205 by 186, we get 6 with a remainder of 89.
Use 6 as the next digit of our solution. 
Result so far: 666.0
If we subtract 1116 from 1205, we get 89.
Bring next digit (9) of the dividend behind the 89 and repeat the process: 899 / 186

Step 7:
If we divide 899 by 186, we get 4 and a remainder of 155.
The next digit of our result is 4. 
Result so far: 6664.0
Deduct 744 from 899 and we're left with 155.
Bring next digit (7) of the dividend behind the 155 and repeat the process: 1557 / 186

On to step 8:
When dividing 1557 by 186, we get 8 with a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 66648.0
Deduct 1488 from 1557 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.

Advancing to step 9:
When dividing 690 by 186, we get 3 with a remainder of 132.
The next digit of our result is 3. 
Result so far: 66648.3
If we take 558 away from 690, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
The number 186 fits into 1320 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 66648.37
If we take 1302 away from 1320, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
186 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 66648.37
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 186 is 9 with a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 66648.3709
If we take 1674 away from 1800, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
186 goes into 1260 6 times with a remainder of 144.
The next digit of our result is 6. 
Result so far: 66648.37096
Subtracting 1116 from 1260 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.

Let's proceed to step 14:
When dividing 1440 by 186, we get 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 66648.370967
If we take 1302 away from 1440, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 15:
The number 186 fits into 1380 7 times, leaving a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 66648.3709677
The remainder is 78 after subtracting 1302 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 66648.3709677, with a leftover of 7.8e-07.
