We're dividing 18378463 by 389 
The aim is to understand the frequency of 389 in 18378463.

Going ahead to step 1:
389 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 389

Moving on to step 2:
389 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 389

Advancing to step 3:
When dividing 183 by 389, we get 0 with a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 183, we end up with 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 389

On to step 4:
The number 389 fits into 1837 4 times, leaving a remainder of 281.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1556 from 1837 to get 281.
Append the next digit (8) from the dividend to 281 and continue with: 2818 / 389

Moving on to step 5:
389 can be fit into 2818 7 times, resulting in a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we subtract 2723 from 2818, we get 95.
Bring next digit (4) of the dividend behind the 95 and repeat the process: 954 / 389

Going ahead to step 6:
389 goes into 954 2 times with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 472.0
Subtracting 778 from 954 leaves us with 176.
Fetch the next digit (6) from the dividend, attach it to 176 and continue: 1766 / 389

Let's proceed to step 7:
389 can be fit into 1766 4 times, resulting in a remainder of 210.
The next digit of our result is 4. 
Result so far: 4724.0
If we take 1556 away from 1766, we end up with 210.
Grab the next digit (3) from the dividend, add it to 210, then carry on: 2103 / 389

Advancing to step 8:
2103 divided by 389 is 5 with a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 47245.0
Deduct 1945 from 2103 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
1580 divided by 389 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 47245.4
Subtract 1556 from 1580 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
389 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 47245.4
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
When dividing 2400 by 389, we get 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 47245.406
The remainder is 66 after subtracting 2334 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
389 can be fit into 660 1 times, resulting in a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 47245.4061
Subtracting 389 from 660 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 13:
389 goes into 2710 6 times with a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 47245.40616
Subtracting 2334 from 2710 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 14:
3760 divided by 389 is 9 with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 47245.406169
If we subtract 3501 from 3760, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 15:
389 can be fit into 2590 6 times, resulting in a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 47245.4061696
If we take 2334 away from 2590, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 16:
When dividing 2560 by 389, we get 6 with a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 47245.40616966
Subtracting 2334 from 2560 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The quotient of the division is 47245.40616966, and the remainder is 2.26e-07.
