Let's divide 66646553 by 386
The aim is to understand the frequency of 386 in 66646553.

Step 1:
386 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 386

On to step 2:
66 divided by 386 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 386

On to step 3:
When dividing 666 by 386, we get 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 386 from 666 to get 280.
Take the next digit (4) from the dividend and append it to 280, then repeat: 2804 / 386

Going ahead to step 4:
2804 divided by 386 is 7 with a remainder of 102.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 2702 from 2804 to get 102.
Fetch the next digit (6) from the dividend, attach it to 102 and continue: 1026 / 386

Moving on to step 5:
386 goes into 1026 2 times with a remainder of 254.
The next digit of our result is 2. 
Result so far: 172.0
Subtracting 772 from 1026 leaves us with 254.
Grab the next digit (5) from the dividend, add it to 254, then carry on: 2545 / 386

Advancing to step 6:
386 goes into 2545 6 times with a remainder of 229.
The next digit of our result is 6. 
Result so far: 1726.0
Subtract 2316 from 2545 to get 229.
Bring next digit (5) of the dividend behind the 229 and repeat the process: 2295 / 386

Advancing to step 7:
386 goes into 2295 5 times with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 17265.0
Subtracting 1930 from 2295 leaves us with 365.
Fetch the next digit (3) from the dividend, attach it to 365 and continue: 3653 / 386

Moving on to step 8:
The number 386 fits into 3653 9 times, leaving a remainder of 179.
The next digit of our result is 9. 
Result so far: 172659.0
Subtract 3474 from 3653 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
When dividing 1790 by 386, we get 4 with a remainder of 246.
Put 4 as the next digit of the answer. 
Result so far: 172659.4
The remainder is 246 after subtracting 1544 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 10:
2460 divided by 386 is 6 with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 172659.46
Subtracting 2316 from 2460 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.

Advancing to step 11:
386 goes into 1440 3 times with a remainder of 282.
Write down 3 as next digit of the result. 
Result so far: 172659.463
Subtract 1158 from 1440 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 12:
386 goes into 2820 7 times with a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 172659.4637
Subtracting 2702 from 2820 leaves us 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.

Step 13:
386 goes into 1180 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 172659.46373
If we take 1158 away from 1180, 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.

Let's proceed to step 14:
386 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 172659.46373
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
386 can be fit into 2200 5 times, resulting in a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 172659.4637305
The remainder is 270 after subtracting 1930 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 16:
386 can be fit into 2700 6 times, resulting in a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 172659.46373056
If we take 2316 away from 2700, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 172659.46373056 with a remainder of 3.84e-07.
