We look at the division of 16749769 by 629 
The aim is to understand the frequency of 629 in 16749769.

Let's proceed to step 1:
629 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 629

Step 2:
The number 629 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 629

Step 3:
When dividing 167 by 629, we get 0 with a remainder of 167.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 167 after subtracting 0 from 167.
Take the next digit (4) from the dividend and append it to 167, then repeat: 1674 / 629

Advancing to step 4:
1674 divided by 629 is 2 with a remainder of 416.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1258 from 1674 to get 416.
Append the next digit (9) from the dividend to 416 and continue with: 4169 / 629

On to step 5:
4169 divided by 629 is 6 with a remainder of 395.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 3774 from 4169 to get 395.
Bring next digit (7) of the dividend behind the 395 and repeat the process: 3957 / 629

Let's proceed to step 6:
629 goes into 3957 6 times with a remainder of 183.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
Subtracting 3774 from 3957 leaves us with 183.
Bring next digit (6) of the dividend behind the 183 and repeat the process: 1836 / 629

Step 7:
If we divide 1836 by 629, we get 2 and a remainder of 578.
Use 2 as the next digit of our solution. 
Result so far: 2662.0
If we take 1258 away from 1836, we end up with 578.
Fetch the next digit (9) from the dividend, attach it to 578 and continue: 5789 / 629

Step 8:
629 goes into 5789 9 times with a remainder of 128.
The next digit of our result is 9. 
Result so far: 26629.0
Deduct 5661 from 5789 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
629 can be fit into 1280 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 26629.2
Subtracting 1258 from 1280 leaves us with 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 10:
629 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: 26629.2
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
2200 divided by 629 is 3 with a remainder of 313.
Write down 3 as next digit of the result. 
Result so far: 26629.203
Deduct 1887 from 2200 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 12:
629 goes into 3130 4 times with a remainder of 614.
Write down 4 as next digit of the result. 
Result so far: 26629.2034
The remainder is 614 after subtracting 2516 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 13:
629 can be fit into 6140 9 times, resulting in a remainder of 479.
The next digit of our result is 9. 
Result so far: 26629.20349
The remainder is 479 after subtracting 5661 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 14:
629 goes into 4790 7 times with a remainder of 387.
The next digit of our result is 7. 
Result so far: 26629.203497
The remainder is 387 after subtracting 4403 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 15:
629 can be fit into 3870 6 times, resulting in a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 26629.2034976
If we take 3774 away from 3870, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
The number 629 fits into 960 1 times, leaving a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 26629.20349761
Subtract 629 from 960 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

After the division, we end up with 26629.20349761 and a remainder of 3.31e-07.
