We divide 89809125 by 31
The aim is to understand the frequency of 31 in 89809125.

Moving on to step 1:
31 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 31

Let's proceed to step 2:
31 goes into 89 2 times with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 62 away from 89, we end up with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 31

Advancing to step 3:
The number 31 fits into 278 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 248 from 278 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 31

On to step 4:
300 divided by 31 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtract 279 from 300 to get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 31

Moving on to step 5:
219 divided by 31 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 2897.0
If we take 217 away from 219, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 31

On to step 6:
21 divided by 31 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 28970.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 31

Advancing to step 7:
212 divided by 31 is 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 289706.0
Subtract 186 from 212 to get 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 31

Step 8:
When dividing 265 by 31, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 2897068.0
The remainder is 17 after subtracting 248 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
If we divide 170 by 31, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2897068.5
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 31, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2897068.54
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
If we divide 260 by 31, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2897068.548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 2897068.5483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
31 goes into 270 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2897068.54838
Subtract 248 from 270 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.

Advancing to step 14:
31 can be fit into 220 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2897068.548387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 15:
When dividing 30 by 31, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 2897068.548387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 16:
300 divided by 31 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2897068.54838709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 2897068.54838709 with a remainder of 2.1e-08.
