We divide 20103003 by 389
The aim is to understand the frequency of 389 in 20103003.

Let's proceed to step 1:
2 divided by 389 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 389

Going ahead to step 2:
If we divide 20 by 389, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 389

Advancing to step 3:
201 divided by 389 is 0 with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 201, we get 201.
Take the next digit (0) from the dividend and append it to 201, then repeat: 2010 / 389

Step 4:
If we divide 2010 by 389, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1945 from 2010 to get 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 389

Let's proceed to step 5:
653 divided by 389 is 1 with a remainder of 264.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 389 from 653, we get 264.
Append the next digit (0) from the dividend to 264 and continue with: 2640 / 389

Advancing to step 6:
If we divide 2640 by 389, we get 6 and a remainder of 306.
Record the quotient 6 as the next digit in the result. 
Result so far: 516.0
If we subtract 2334 from 2640, we get 306.
Take the next digit (0) from the dividend and append it to 306, then repeat: 3060 / 389

Let's proceed to step 7:
389 goes into 3060 7 times with a remainder of 337.
Write down 7 as next digit of the result. 
Result so far: 5167.0
Deduct 2723 from 3060 and we're left with 337.
Append the next digit (3) from the dividend to 337 and continue with: 3373 / 389

Step 8:
389 goes into 3373 8 times with a remainder of 261.
Record the quotient 8 as the next digit in the result. 
Result so far: 51678.0
If we subtract 3112 from 3373, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 9:
If we divide 2610 by 389, we get 6 and a remainder of 276.
The next digit of our result is 6. 
Result so far: 51678.6
If we take 2334 away from 2610, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
When dividing 2760 by 389, we get 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 51678.67
The remainder is 37 after subtracting 2723 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
The number 389 fits into 370 0 times, leaving a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 51678.67
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 12:
If we divide 3700 by 389, we get 9 and a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 51678.6709
Subtract 3501 from 3700 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 13:
389 can be fit into 1990 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 51678.67095
Subtracting 1945 from 1990 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
389 goes into 450 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 51678.670951
If we take 389 away from 450, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 15:
The number 389 fits into 610 1 times, leaving a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 51678.6709511
Subtracting 389 from 610 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

In conclusion, the division gives 51678.6709511 with a balance of 2.21e-06.
