Let's divide 29871622 by 389
The aim is to understand the frequency of 389 in 29871622.

Advancing to step 1:
389 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 389

On to step 2:
389 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 389

Let's proceed to step 3:
298 divided by 389 is 0 with a remainder of 298.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 298, we get 298.
Grab the next digit (7) from the dividend, add it to 298, then carry on: 2987 / 389

Step 4:
2987 divided by 389 is 7 with a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 2723 from 2987 and we're left with 264.
Take the next digit (1) from the dividend and append it to 264, then repeat: 2641 / 389

Advancing to step 5:
If we divide 2641 by 389, we get 6 and a remainder of 307.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 2334 from 2641 to get 307.
Grab the next digit (6) from the dividend, add it to 307, then carry on: 3076 / 389

Advancing to step 6:
389 can be fit into 3076 7 times, resulting in a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 767.0
Subtracting 2723 from 3076 leaves us with 353.
Include the next digit (2) from the dividend after 353, then repeat: 3532 / 389

Advancing to step 7:
389 can be fit into 3532 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 7679.0
Deduct 3501 from 3532 and we're left with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 389

Advancing to step 8:
If we divide 312 by 389, we get 0 and a remainder of 312.
The next digit of our result is 0. 
Result so far: 76790.0
Deduct 0 from 312 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
3120 divided by 389 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 76790.8
Deduct 3112 from 3120 and we're left 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 10:
389 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 76790.8
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.

Moving on to step 11:
When dividing 800 by 389, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 76790.802
Subtract 778 from 800 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
220 divided by 389 is 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 76790.802
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
2200 divided by 389 is 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 76790.80205
The remainder is 255 after subtracting 1945 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 14:
389 goes into 2550 6 times with a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 76790.802056
Subtract 2334 from 2550 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
The number 389 fits into 2160 5 times, leaving a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 76790.8020565
Subtract 1945 from 2160 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 16:
When dividing 2150 by 389, we get 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 76790.80205655
Subtracting 1945 from 2150 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

In conclusion, the division gives 76790.80205655 with a balance of 2.05e-07.
