42541647 divided by 629 
The aim is to understand the frequency of 629 in 42541647.

On to step 1:
If we divide 4 by 629, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 629

Step 2:
629 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 629

Advancing to step 3:
425 divided by 629 is 0 with a remainder of 425.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Fetch the next digit (4) from the dividend, attach it to 425 and continue: 4254 / 629

Going ahead to step 4:
4254 divided by 629 is 6 with a remainder of 480.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 480 after subtracting 3774 from 4254.
Include the next digit (1) from the dividend after 480, then repeat: 4801 / 629

Let's proceed to step 5:
The number 629 fits into 4801 7 times, leaving a remainder of 398.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 4403 from 4801, we get 398.
Fetch the next digit (6) from the dividend, attach it to 398 and continue: 3986 / 629

Step 6:
The number 629 fits into 3986 6 times, leaving a remainder of 212.
The next digit of our result is 6. 
Result so far: 676.0
If we take 3774 away from 3986, we end up with 212.
Grab the next digit (4) from the dividend, add it to 212, then carry on: 2124 / 629

Moving on to step 7:
The number 629 fits into 2124 3 times, leaving a remainder of 237.
The number 3 becomes the next digit in our result. 
Result so far: 6763.0
Subtracting 1887 from 2124 leaves us with 237.
Grab the next digit (7) from the dividend, add it to 237, then carry on: 2377 / 629

On to step 8:
The number 629 fits into 2377 3 times, leaving a remainder of 490.
Put 3 as the next digit of the answer. 
Result so far: 67633.0
If we take 1887 away from 2377, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 9:
The number 629 fits into 4900 7 times, leaving a remainder of 497.
The next digit of our result is 7. 
Result so far: 67633.7
Subtract 4403 from 4900 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

On to step 10:
When dividing 4970 by 629, we get 7 with a remainder of 567.
Write down 7 as next digit of the result. 
Result so far: 67633.77
Subtracting 4403 from 4970 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

The quotient of the division is 67633.77, and the remainder is 0.567.
