33938286 ÷ 629 
The aim is to understand the frequency of 629 in 33938286.

Step 1:
If we divide 3 by 629, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 629

Advancing to step 2:
When dividing 33 by 629, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 629

On to step 3:
When dividing 339 by 629, we get 0 with a remainder of 339.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 339 to get 339.
Include the next digit (3) from the dividend after 339, then repeat: 3393 / 629

Step 4:
629 goes into 3393 5 times with a remainder of 248.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3145 from 3393 leaves us with 248.
Fetch the next digit (8) from the dividend, attach it to 248 and continue: 2488 / 629

On to step 5:
629 can be fit into 2488 3 times, resulting in a remainder of 601.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 1887 away from 2488, we end up with 601.
Bring next digit (2) of the dividend behind the 601 and repeat the process: 6012 / 629

Moving on to step 6:
If we divide 6012 by 629, we get 9 and a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 539.0
The remainder is 351 after subtracting 5661 from 6012.
Fetch the next digit (8) from the dividend, attach it to 351 and continue: 3518 / 629

On to step 7:
The number 629 fits into 3518 5 times, leaving a remainder of 373.
Record the quotient 5 as the next digit in the result. 
Result so far: 5395.0
Subtract 3145 from 3518 to get 373.
Take the next digit (6) from the dividend and append it to 373, then repeat: 3736 / 629

Advancing to step 8:
When dividing 3736 by 629, we get 5 with a remainder of 591.
Use 5 as the next digit of our solution. 
Result so far: 53955.0
If we subtract 3145 from 3736, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 9:
5910 divided by 629 is 9 with a remainder of 249.
The number 9 becomes the next digit in our result. 
Result so far: 53955.9
Subtracting 5661 from 5910 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 10:
The number 629 fits into 2490 3 times, leaving a remainder of 603.
The next digit of our result is 3. 
Result so far: 53955.93
Subtracting 1887 from 2490 leaves us with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 11:
When dividing 6030 by 629, we get 9 with a remainder of 369.
Use 9 as the next digit of our solution. 
Result so far: 53955.939
The remainder is 369 after subtracting 5661 from 6030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 12:
629 goes into 3690 5 times with a remainder of 545.
The number 5 becomes the next digit in our result. 
Result so far: 53955.9395
If we take 3145 away from 3690, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 13:
5450 divided by 629 is 8 with a remainder of 418.
Use 8 as the next digit of our solution. 
Result so far: 53955.93958
If we take 5032 away from 5450, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 14:
When dividing 4180 by 629, we get 6 with a remainder of 406.
Put 6 as the next digit of the answer. 
Result so far: 53955.939586
The remainder is 406 after subtracting 3774 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 15:
4060 divided by 629 is 6 with a remainder of 286.
Record the quotient 6 as the next digit in the result. 
Result so far: 53955.9395866
The remainder is 286 after subtracting 3774 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 53955.9395866 with a remainder of 2.86e-06.
