Let's divide 31731143 by 613
The aim is to understand the frequency of 613 in 31731143.

Moving on to step 1:
When dividing 3 by 613, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 613

On to step 2:
If we divide 31 by 613, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 613

On to step 3:
When dividing 317 by 613, we get 0 with a remainder of 317.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 317 to get 317.
Include the next digit (3) from the dividend after 317, then repeat: 3173 / 613

Let's proceed to step 4:
The number 613 fits into 3173 5 times, leaving a remainder of 108.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3065 from 3173 to get 108.
Grab the next digit (1) from the dividend, add it to 108, then carry on: 1081 / 613

On to step 5:
If we divide 1081 by 613, we get 1 and a remainder of 468.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 613 away from 1081, we end up with 468.
Grab the next digit (1) from the dividend, add it to 468, then carry on: 4681 / 613

Moving on to step 6:
The number 613 fits into 4681 7 times, leaving a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
If we take 4291 away from 4681, we end up with 390.
Include the next digit (4) from the dividend after 390, then repeat: 3904 / 613

Advancing to step 7:
When dividing 3904 by 613, we get 6 with a remainder of 226.
The next digit of our result is 6. 
Result so far: 5176.0
If we take 3678 away from 3904, we end up with 226.
Append the next digit (3) from the dividend to 226 and continue with: 2263 / 613

Step 8:
613 can be fit into 2263 3 times, resulting in a remainder of 424.
Write down 3 as next digit of the result. 
Result so far: 51763.0
If we take 1839 away from 2263, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 9:
When dividing 4240 by 613, we get 6 with a remainder of 562.
The number 6 becomes the next digit in our result. 
Result so far: 51763.6
If we subtract 3678 from 4240, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 10:
613 can be fit into 5620 9 times, resulting in a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 51763.69
Subtract 5517 from 5620 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 11:
613 goes into 1030 1 times with a remainder of 417.
The number 1 becomes the next digit in our result. 
Result so far: 51763.691
Subtract 613 from 1030 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 12:
The number 613 fits into 4170 6 times, leaving a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 51763.6916
Subtracting 3678 from 4170 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 13:
4920 divided by 613 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 51763.69168
Subtract 4904 from 4920 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
The number 613 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 51763.69168
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
613 goes into 1600 2 times with a remainder of 374.
The next digit of our result is 2. 
Result so far: 51763.6916802
If we take 1226 away from 1600, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 16:
613 can be fit into 3740 6 times, resulting in a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 51763.69168026
If we subtract 3678 from 3740, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 51763.69168026, with a leftover of 6.2e-08.
