We look at the division of 81064953 by 386 
The aim is to understand the frequency of 386 in 81064953.

Advancing to step 1:
8 divided by 386 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 386

Moving on to step 2:
81 divided by 386 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 386

Step 3:
When dividing 810 by 386, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 772 from 810 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 386

On to step 4:
When dividing 386 by 386, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
If we take 386 away from 386, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 386

On to step 5:
The number 386 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 210.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 386

Let's proceed to step 6:
If we divide 49 by 386, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 2100.0
If we take 0 away from 49, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 386

Moving on to step 7:
When dividing 495 by 386, we get 1 with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 21001.0
Subtracting 386 from 495 leaves us with 109.
Bring next digit (3) of the dividend behind the 109 and repeat the process: 1093 / 386

Let's proceed to step 8:
When dividing 1093 by 386, we get 2 with a remainder of 321.
The next digit of our result is 2. 
Result so far: 210012.0
Subtracting 772 from 1093 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 9:
When dividing 3210 by 386, we get 8 with a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 210012.8
The remainder is 122 after subtracting 3088 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
If we divide 1220 by 386, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 210012.83
The remainder is 62 after subtracting 1158 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
The number 386 fits into 620 1 times, leaving a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 210012.831
Deduct 386 from 620 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 12:
386 can be fit into 2340 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 210012.8316
The remainder is 24 after subtracting 2316 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 386, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 210012.8316
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
386 goes into 2400 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 210012.831606
Subtracting 2316 from 2400 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
If we divide 840 by 386, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 210012.8316062
The remainder is 68 after subtracting 772 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
386 goes into 680 1 times with a remainder of 294.
Write down 1 as next digit of the result. 
Result so far: 210012.83160621
The remainder is 294 after subtracting 386 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The quotient of the division is 210012.83160621, and the remainder is 2.94e-07.
