We look at the division of 64396152 by 386 
The aim is to understand the frequency of 386 in 64396152.

Moving on to step 1:
386 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 386

Let's proceed to step 2:
386 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 386

Step 3:
If we divide 643 by 386, we get 1 and a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 386 from 643 leaves us with 257.
Bring next digit (9) of the dividend behind the 257 and repeat the process: 2579 / 386

Advancing to step 4:
If we divide 2579 by 386, we get 6 and a remainder of 263.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 263 after subtracting 2316 from 2579.
Fetch the next digit (6) from the dividend, attach it to 263 and continue: 2636 / 386

On to step 5:
386 goes into 2636 6 times with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we take 2316 away from 2636, we end up with 320.
Take the next digit (1) from the dividend and append it to 320, then repeat: 3201 / 386

Going ahead to step 6:
386 goes into 3201 8 times with a remainder of 113.
The next digit of our result is 8. 
Result so far: 1668.0
Subtract 3088 from 3201 to get 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 386

Moving on to step 7:
The number 386 fits into 1135 2 times, leaving a remainder of 363.
Record the quotient 2 as the next digit in the result. 
Result so far: 16682.0
Subtracting 772 from 1135 leaves us with 363.
Fetch the next digit (2) from the dividend, attach it to 363 and continue: 3632 / 386

Let's proceed to step 8:
386 can be fit into 3632 9 times, resulting in a remainder of 158.
The next digit of our result is 9. 
Result so far: 166829.0
Subtract 3474 from 3632 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
The number 386 fits into 1580 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 166829.4
If we subtract 1544 from 1580, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 386, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 166829.4
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
When dividing 3600 by 386, we get 9 with a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 166829.409
The remainder is 126 after subtracting 3474 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 12:
The number 386 fits into 1260 3 times, leaving a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 166829.4093
Deduct 1158 from 1260 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 13:
386 can be fit into 1020 2 times, resulting in a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 166829.40932
If we take 772 away from 1020, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
386 can be fit into 2480 6 times, resulting in a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 166829.409326
If we take 2316 away from 2480, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
386 can be fit into 1640 4 times, resulting in a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 166829.4093264
Deduct 1544 from 1640 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 16:
960 divided by 386 is 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 166829.40932642
Deduct 772 from 960 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 166829.40932642 with a remainder of 1.88e-07.
