We look at the division of 80991349 by 386 
The aim is to understand the frequency of 386 in 80991349.

Let's proceed to step 1:
The number 386 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 386

Step 2:
386 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 386

Step 3:
The number 386 fits into 809 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 772 from 809 leaves us with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 386

Going ahead to step 4:
386 goes into 379 0 times with a remainder of 379.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 379, we get 379.
Fetch the next digit (1) from the dividend, attach it to 379 and continue: 3791 / 386

Let's proceed to step 5:
386 can be fit into 3791 9 times, resulting in a remainder of 317.
Write down 9 as next digit of the result. 
Result so far: 209.0
If we subtract 3474 from 3791, we get 317.
Fetch the next digit (3) from the dividend, attach it to 317 and continue: 3173 / 386

Moving on to step 6:
When dividing 3173 by 386, we get 8 with a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 2098.0
The remainder is 85 after subtracting 3088 from 3173.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 386

Step 7:
If we divide 854 by 386, we get 2 and a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 20982.0
Subtracting 772 from 854 leaves us with 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 386

Let's proceed to step 8:
386 can be fit into 829 2 times, resulting in a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 209822.0
If we subtract 772 from 829, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
When dividing 570 by 386, we get 1 with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 209822.1
If we subtract 386 from 570, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 10:
386 goes into 1840 4 times with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 209822.14
Subtracting 1544 from 1840 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 11:
386 can be fit into 2960 7 times, resulting in a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 209822.147
Deduct 2702 from 2960 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 12:
When dividing 2580 by 386, we get 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 209822.1476
Subtract 2316 from 2580 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 13:
If we divide 2640 by 386, we get 6 and a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 209822.14766
If we subtract 2316 from 2640, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Our division results in 209822.14766 with a remaining 0.000324.
