We look at the division of 19508259 by 626 
The aim is to understand the frequency of 626 in 19508259.

On to step 1:
When dividing 1 by 626, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 626

Step 2:
If we divide 19 by 626, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 626

Advancing to step 3:
If we divide 195 by 626, we get 0 and a remainder of 195.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 195 leaves us with 195.
Include the next digit (0) from the dividend after 195, then repeat: 1950 / 626

Let's proceed to step 4:
1950 divided by 626 is 3 with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1878 from 1950 and we're left with 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 626

Moving on to step 5:
The number 626 fits into 728 1 times, leaving a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 626 from 728 to get 102.
Take the next digit (2) from the dividend and append it to 102, then repeat: 1022 / 626

Step 6:
When dividing 1022 by 626, we get 1 with a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we subtract 626 from 1022, we get 396.
Include the next digit (5) from the dividend after 396, then repeat: 3965 / 626

Moving on to step 7:
3965 divided by 626 is 6 with a remainder of 209.
The number 6 becomes the next digit in our result. 
Result so far: 3116.0
Subtracting 3756 from 3965 leaves us with 209.
Take the next digit (9) from the dividend and append it to 209, then repeat: 2099 / 626

Advancing to step 8:
The number 626 fits into 2099 3 times, leaving a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 31163.0
If we subtract 1878 from 2099, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
2210 divided by 626 is 3 with a remainder of 332.
Record the quotient 3 as the next digit in the result. 
Result so far: 31163.3
If we take 1878 away from 2210, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
626 goes into 3320 5 times with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 31163.35
Subtracting 3130 from 3320 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
626 can be fit into 1900 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 31163.353
If we subtract 1878 from 1900, we 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.

Going ahead to step 12:
626 can be fit into 220 0 times, resulting in a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 31163.353
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
2200 divided by 626 is 3 with a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 31163.35303
Subtracting 1878 from 2200 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 14:
626 goes into 3220 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 31163.353035
If we take 3130 away from 3220, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 626 is 1 with a remainder of 274.
Record the quotient 1 as the next digit in the result. 
Result so far: 31163.3530351
If we take 626 away from 900, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 16:
2740 divided by 626 is 4 with a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 31163.35303514
Subtracting 2504 from 2740 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 31163.35303514, with a leftover of 2.36e-07.
