We're dividing 71315543 by 289 
The aim is to understand the frequency of 289 in 71315543.

Going ahead to step 1:
When dividing 7 by 289, we get 0 with 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.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 289

Let's proceed to step 2:
The number 289 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 289

Advancing to step 3:
289 goes into 713 2 times with a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 135 after subtracting 578 from 713.
Include the next digit (1) from the dividend after 135, then repeat: 1351 / 289

On to step 4:
The number 289 fits into 1351 4 times, leaving a remainder of 195.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 1156 from 1351, we get 195.
Fetch the next digit (5) from the dividend, attach it to 195 and continue: 1955 / 289

Advancing to step 5:
When dividing 1955 by 289, we get 6 with a remainder of 221.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Subtract 1734 from 1955 to get 221.
Grab the next digit (5) from the dividend, add it to 221, then carry on: 2215 / 289

Going ahead to step 6:
When dividing 2215 by 289, we get 7 with a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 2467.0
Subtracting 2023 from 2215 leaves us with 192.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 289

On to step 7:
When dividing 1924 by 289, we get 6 with a remainder of 190.
Write down 6 as next digit of the result. 
Result so far: 24676.0
If we take 1734 away from 1924, we end up with 190.
Take the next digit (3) from the dividend and append it to 190, then repeat: 1903 / 289

On to step 8:
The number 289 fits into 1903 6 times, leaving a remainder of 169.
The next digit of our result is 6. 
Result so far: 246766.0
If we subtract 1734 from 1903, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 9:
289 goes into 1690 5 times with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 246766.5
The remainder is 245 after subtracting 1445 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 10:
The number 289 fits into 2450 8 times, leaving a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 246766.58
If we subtract 2312 from 2450, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
1380 divided by 289 is 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 246766.584
Subtract 1156 from 1380 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
When dividing 2240 by 289, we get 7 with a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 246766.5847
Subtract 2023 from 2240 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 13:
2170 divided by 289 is 7 with a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 246766.58477
The remainder is 147 after subtracting 2023 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

After the division, we end up with 246766.58477 and a remainder of 0.000147.
