We're dividing 13420981 by 186 
The aim is to understand the frequency of 186 in 13420981.

Let's proceed to step 1:
The number 186 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 186

Moving on to step 2:
The number 186 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 186

Advancing to step 3:
134 divided by 186 is 0 with a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 134 leaves us with 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 186

Going ahead to step 4:
The number 186 fits into 1342 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 40 after subtracting 1302 from 1342.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 186

On to step 5:
If we divide 400 by 186, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 372 away from 400, we end up with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 186

Advancing to step 6:
289 divided by 186 is 1 with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 721.0
The remainder is 103 after subtracting 186 from 289.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 186

Step 7:
If we divide 1038 by 186, we get 5 and a remainder of 108.
The number 5 becomes the next digit in our result. 
Result so far: 7215.0
If we take 930 away from 1038, we end up with 108.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 186

Let's proceed to step 8:
When dividing 1081 by 186, we get 5 with a remainder of 151.
The number 5 becomes the next digit in our result. 
Result so far: 72155.0
If we subtract 930 from 1081, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 9:
If we divide 1510 by 186, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 72155.8
If we take 1488 away from 1510, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
When dividing 220 by 186, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 72155.81
Deduct 186 from 220 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
If we divide 340 by 186, we get 1 and a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 72155.811
The remainder is 154 after subtracting 186 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 72155.811 with a balance of 0.0154.
