Let's divide 31145531 by 717
The aim is to understand the frequency of 717 in 31145531.

Let's proceed to step 1:
3 divided by 717 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 717

Advancing to step 2:
717 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 717

Let's proceed to step 3:
The number 717 fits into 311 0 times, leaving a remainder of 311.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 311 to get 311.
Grab the next digit (4) from the dividend, add it to 311, then carry on: 3114 / 717

Let's proceed to step 4:
If we divide 3114 by 717, we get 4 and a remainder of 246.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2868 from 3114 to get 246.
Grab the next digit (5) from the dividend, add it to 246, then carry on: 2465 / 717

Going ahead to step 5:
When dividing 2465 by 717, we get 3 with a remainder of 314.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 2151 from 2465 to get 314.
Append the next digit (5) from the dividend to 314 and continue with: 3145 / 717

Going ahead to step 6:
The number 717 fits into 3145 4 times, leaving a remainder of 277.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Subtracting 2868 from 3145 leaves us with 277.
Include the next digit (3) from the dividend after 277, then repeat: 2773 / 717

Let's proceed to step 7:
717 can be fit into 2773 3 times, resulting in a remainder of 622.
Use 3 as the next digit of our solution. 
Result so far: 4343.0
Subtract 2151 from 2773 to get 622.
Append the next digit (1) from the dividend to 622 and continue with: 6221 / 717

Step 8:
6221 divided by 717 is 8 with a remainder of 485.
The next digit of our result is 8. 
Result so far: 43438.0
Subtract 5736 from 6221 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 9:
4850 divided by 717 is 6 with a remainder of 548.
Use 6 as the next digit of our solution. 
Result so far: 43438.6
Deduct 4302 from 4850 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 10:
5480 divided by 717 is 7 with a remainder of 461.
The next digit of our result is 7. 
Result so far: 43438.67
Subtracting 5019 from 5480 leaves us with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 11:
717 can be fit into 4610 6 times, resulting in a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 43438.676
Subtract 4302 from 4610 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 12:
717 can be fit into 3080 4 times, resulting in a remainder of 212.
The next digit of our result is 4. 
Result so far: 43438.6764
If we subtract 2868 from 3080, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
When dividing 2120 by 717, we get 2 with a remainder of 686.
Put 2 as the next digit of the answer. 
Result so far: 43438.67642
Deduct 1434 from 2120 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 14:
When dividing 6860 by 717, we get 9 with a remainder of 407.
Put 9 as the next digit of the answer. 
Result so far: 43438.676429
Subtracting 6453 from 6860 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 15:
The number 717 fits into 4070 5 times, leaving a remainder of 485.
The next digit of our result is 5. 
Result so far: 43438.6764295
If we take 3585 away from 4070, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 16:
If we divide 4850 by 717, we get 6 and a remainder of 548.
Write down 6 as next digit of the result. 
Result so far: 43438.67642956
Deduct 4302 from 4850 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

In conclusion, the division gives 43438.67642956 with a balance of 5.48e-07.
