We're dividing 31449096 by 626 
The aim is to understand the frequency of 626 in 31449096.

Step 1:
The number 626 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 626

Advancing to step 2:
626 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 626

On to step 3:
314 divided by 626 is 0 with a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 314 and we're left with 314.
Fetch the next digit (4) from the dividend, attach it to 314 and continue: 3144 / 626

On to step 4:
If we divide 3144 by 626, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3130 from 3144, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 626

Let's proceed to step 5:
626 can be fit into 149 0 times, resulting in a remainder of 149.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 149, we get 149.
Take the next digit (0) from the dividend and append it to 149, then repeat: 1490 / 626

Moving on to step 6:
The number 626 fits into 1490 2 times, leaving a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 502.0
The remainder is 238 after subtracting 1252 from 1490.
Take the next digit (9) from the dividend and append it to 238, then repeat: 2389 / 626

Step 7:
626 can be fit into 2389 3 times, resulting in a remainder of 511.
Write down 3 as next digit of the result. 
Result so far: 5023.0
If we subtract 1878 from 2389, we get 511.
Bring next digit (6) of the dividend behind the 511 and repeat the process: 5116 / 626

Going ahead to step 8:
When dividing 5116 by 626, we get 8 with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 50238.0
The remainder is 108 after subtracting 5008 from 5116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 9:
1080 divided by 626 is 1 with a remainder of 454.
Write down 1 as next digit of the result. 
Result so far: 50238.1
If we take 626 away from 1080, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 10:
626 goes into 4540 7 times with a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 50238.17
Subtracting 4382 from 4540 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 11:
1580 divided by 626 is 2 with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 50238.172
Subtract 1252 from 1580 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
626 can be fit into 3280 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 50238.1725
Subtracting 3130 from 3280 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
1500 divided by 626 is 2 with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 50238.17252
Subtracting 1252 from 1500 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
When dividing 2480 by 626, we get 3 with a remainder of 602.
Write down 3 as next digit of the result. 
Result so far: 50238.172523
Subtract 1878 from 2480 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 15:
626 goes into 6020 9 times with a remainder of 386.
Put 9 as the next digit of the answer. 
Result so far: 50238.1725239
If we take 5634 away from 6020, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 16:
3860 divided by 626 is 6 with a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 50238.17252396
If we take 3756 away from 3860, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 50238.17252396, with a leftover of 1.04e-07.
