We're dividing 64912449 by 186 
The aim is to understand the frequency of 186 in 64912449.

Going ahead to step 1:
186 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 186

Step 2:
When dividing 64 by 186, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 186

Advancing to step 3:
186 can be fit into 649 3 times, resulting in a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 558 from 649 to get 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 186

Advancing to step 4:
If we divide 911 by 186, we get 4 and a remainder of 167.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 744 from 911, we get 167.
Append the next digit (2) from the dividend to 167 and continue with: 1672 / 186

Step 5:
186 can be fit into 1672 8 times, resulting in a remainder of 184.
The next digit of our result is 8. 
Result so far: 348.0
Subtract 1488 from 1672 to get 184.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 186

On to step 6:
186 can be fit into 1844 9 times, resulting in a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 3489.0
Subtracting 1674 from 1844 leaves us with 170.
Take the next digit (4) from the dividend and append it to 170, then repeat: 1704 / 186

Moving on to step 7:
186 goes into 1704 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 34899.0
If we take 1674 away from 1704, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 186

Step 8:
When dividing 309 by 186, we get 1 with a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 348991.0
Deduct 186 from 309 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
186 goes into 1230 6 times with a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 348991.6
If we take 1116 away from 1230, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
If we divide 1140 by 186, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 348991.66
The remainder is 24 after subtracting 1116 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 348991.66, and the remainder is 0.024.
