We look at the division of 73765779 by 389 
The aim is to understand the frequency of 389 in 73765779.

Advancing to step 1:
If we divide 7 by 389, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 389

On to step 2:
73 divided by 389 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (7) from the dividend, add it to 73, then carry on: 737 / 389

Step 3:
If we divide 737 by 389, we get 1 and a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 389 away from 737, we end up with 348.
Grab the next digit (6) from the dividend, add it to 348, then carry on: 3486 / 389

Let's proceed to step 4:
When dividing 3486 by 389, we get 8 with a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3112 from 3486 leaves us with 374.
Bring next digit (5) of the dividend behind the 374 and repeat the process: 3745 / 389

Advancing to step 5:
389 goes into 3745 9 times with a remainder of 244.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Deduct 3501 from 3745 and we're left with 244.
Include the next digit (7) from the dividend after 244, then repeat: 2447 / 389

Going ahead to step 6:
The number 389 fits into 2447 6 times, leaving a remainder of 113.
Write down 6 as next digit of the result. 
Result so far: 1896.0
If we take 2334 away from 2447, we end up with 113.
Bring next digit (7) of the dividend behind the 113 and repeat the process: 1137 / 389

Moving on to step 7:
389 can be fit into 1137 2 times, resulting in a remainder of 359.
Use 2 as the next digit of our solution. 
Result so far: 18962.0
Subtracting 778 from 1137 leaves us with 359.
Append the next digit (9) from the dividend to 359 and continue with: 3599 / 389

Step 8:
3599 divided by 389 is 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 189629.0
If we take 3501 away from 3599, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 9:
389 goes into 980 2 times with a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 189629.2
If we take 778 away from 980, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
389 goes into 2020 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 189629.25
The remainder is 75 after subtracting 1945 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
389 can be fit into 750 1 times, resulting in a remainder of 361.
Use 1 as the next digit of our solution. 
Result so far: 189629.251
The remainder is 361 after subtracting 389 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 12:
The number 389 fits into 3610 9 times, leaving a remainder of 109.
The next digit of our result is 9. 
Result so far: 189629.2519
The remainder is 109 after subtracting 3501 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 13:
If we divide 1090 by 389, we get 2 and a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 189629.25192
The remainder is 312 after subtracting 778 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 14:
389 can be fit into 3120 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 189629.251928
Subtracting 3112 from 3120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 15:
The number 389 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 189629.251928
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
389 goes into 800 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 189629.25192802
Deduct 778 from 800 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 189629.25192802 with a balance of 2.2e-08.
