Let's divide 78689255 by 289
The aim is to understand the frequency of 289 in 78689255.

Step 1:
When dividing 7 by 289, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 289

Step 2:
If we divide 78 by 289, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 289

Advancing to step 3:
289 goes into 786 2 times with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 578 from 786 to get 208.
Fetch the next digit (8) from the dividend, attach it to 208 and continue: 2088 / 289

Moving on to step 4:
2088 divided by 289 is 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 2023 from 2088 leaves us with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 289

Step 5:
289 goes into 659 2 times with a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 272.0
If we take 578 away from 659, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 289

Advancing to step 6:
812 divided by 289 is 2 with a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 2722.0
Deduct 578 from 812 and we're left with 234.
Bring next digit (5) of the dividend behind the 234 and repeat the process: 2345 / 289

Step 7:
If we divide 2345 by 289, we get 8 and a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 27228.0
The remainder is 33 after subtracting 2312 from 2345.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 289

Going ahead to step 8:
289 can be fit into 335 1 times, resulting in a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 272281.0
Deduct 289 from 335 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
289 goes into 460 1 times with a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 272281.1
If we subtract 289 from 460, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 10:
1710 divided by 289 is 5 with a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 272281.15
Subtract 1445 from 1710 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 11:
2650 divided by 289 is 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 272281.159
If we subtract 2601 from 2650, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
490 divided by 289 is 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 272281.1591
Subtracting 289 from 490 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 13:
When dividing 2010 by 289, we get 6 with a remainder of 276.
Record the quotient 6 as the next digit in the result. 
Result so far: 272281.15916
The remainder is 276 after subtracting 1734 from 2010.
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 14:
2760 divided by 289 is 9 with a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 272281.159169
Deduct 2601 from 2760 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 15:
When dividing 1590 by 289, we get 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 272281.1591695
If we subtract 1445 from 1590, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 16:
1450 divided by 289 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 272281.15916955
If we subtract 1445 from 1450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 272281.15916955, with a leftover of 5e-09.
