Let's divide 70085312 by 289
The aim is to understand the frequency of 289 in 70085312.

Going ahead to step 1:
289 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 289

Advancing to step 2:
The number 289 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 289

Moving on to step 3:
289 goes into 700 2 times with a remainder of 122.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 578 from 700, we get 122.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 289

Moving on to step 4:
When dividing 1228 by 289, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1156 away from 1228, we end up with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 289

Let's proceed to step 5:
725 divided by 289 is 2 with a remainder of 147.
Put 2 as the next digit of the answer. 
Result so far: 242.0
Subtracting 578 from 725 leaves us with 147.
Grab the next digit (3) from the dividend, add it to 147, then carry on: 1473 / 289

Advancing to step 6:
1473 divided by 289 is 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 2425.0
The remainder is 28 after subtracting 1445 from 1473.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 289

Advancing to step 7:
The number 289 fits into 281 0 times, leaving a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 24250.0
Subtracting 0 from 281 leaves us with 281.
Take the next digit (2) from the dividend and append it to 281, then repeat: 2812 / 289

Advancing to step 8:
289 goes into 2812 9 times with a remainder of 211.
Use 9 as the next digit of our solution. 
Result so far: 242509.0
If we take 2601 away from 2812, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
289 can be fit into 2110 7 times, resulting in a remainder of 87.
The next digit of our result is 7. 
Result so far: 242509.7
Subtracting 2023 from 2110 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 10:
When dividing 870 by 289, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 242509.73
The remainder is 3 after subtracting 867 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
289 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 242509.73
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
289 goes into 300 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 242509.7301
If we take 289 away from 300, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
289 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 242509.7301
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
When dividing 1100 by 289, we get 3 with a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 242509.730103
If we take 867 away from 1100, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 15:
289 goes into 2330 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 242509.7301038
The remainder is 18 after subtracting 2312 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 16:
When dividing 180 by 289, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 242509.7301038
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 242509.7301038, with a leftover of 1.8e-07.
