29976385 ÷ 289 
The aim is to understand the frequency of 289 in 29976385.

Going ahead to step 1:
289 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 289

Let's proceed to step 2:
29 divided by 289 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 289

Going ahead to step 3:
289 can be fit into 299 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 289 away from 299, we end up with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 289

Advancing to step 4:
If we divide 107 by 289, we get 0 and a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 107 leaves us with 107.
Append the next digit (6) from the dividend to 107 and continue with: 1076 / 289

Going ahead to step 5:
1076 divided by 289 is 3 with a remainder of 209.
The next digit of our result is 3. 
Result so far: 103.0
Subtract 867 from 1076 to get 209.
Take the next digit (3) from the dividend and append it to 209, then repeat: 2093 / 289

Moving on to step 6:
289 goes into 2093 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1037.0
If we subtract 2023 from 2093, we get 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 289

Advancing to step 7:
289 can be fit into 708 2 times, resulting in a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 10372.0
Subtract 578 from 708 to get 130.
Bring next digit (5) of the dividend behind the 130 and repeat the process: 1305 / 289

Let's proceed to step 8:
289 can be fit into 1305 4 times, resulting in a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 103724.0
The remainder is 149 after subtracting 1156 from 1305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 9:
289 can be fit into 1490 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 103724.5
The remainder is 45 after subtracting 1445 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
289 goes into 450 1 times with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 103724.51
Deduct 289 from 450 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 11:
When dividing 1610 by 289, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 103724.515
Subtracting 1445 from 1610 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 12:
289 can be fit into 1650 5 times, resulting in a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 103724.5155
Subtract 1445 from 1650 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 103724.5155, with a leftover of 0.00205.
