Let's divide 42099147 by 829
The aim is to understand the frequency of 829 in 42099147.

Step 1:
When dividing 4 by 829, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 829

On to step 2:
829 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 829

Step 3:
When dividing 420 by 829, we get 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Include the next digit (9) from the dividend after 420, then repeat: 4209 / 829

Step 4:
4209 divided by 829 is 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 64 after subtracting 4145 from 4209.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 829

Moving on to step 5:
The number 829 fits into 649 0 times, leaving a remainder of 649.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 649, we end up with 649.
Append the next digit (1) from the dividend to 649 and continue with: 6491 / 829

Step 6:
The number 829 fits into 6491 7 times, leaving a remainder of 688.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we subtract 5803 from 6491, we get 688.
Bring next digit (4) of the dividend behind the 688 and repeat the process: 6884 / 829

On to step 7:
When dividing 6884 by 829, we get 8 with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 5078.0
Subtracting 6632 from 6884 leaves us with 252.
Include the next digit (7) from the dividend after 252, then repeat: 2527 / 829

Advancing to step 8:
The number 829 fits into 2527 3 times, leaving a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 50783.0
Subtracting 2487 from 2527 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 829, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 50783.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
The number 829 fits into 4000 4 times, leaving a remainder of 684.
Record the quotient 4 as the next digit in the result. 
Result so far: 50783.04
Deduct 3316 from 4000 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 11:
If we divide 6840 by 829, we get 8 and a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 50783.048
The remainder is 208 after subtracting 6632 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 12:
If we divide 2080 by 829, we get 2 and a remainder of 422.
Put 2 as the next digit of the answer. 
Result so far: 50783.0482
If we take 1658 away from 2080, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 13:
The number 829 fits into 4220 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 50783.04825
Subtracting 4145 from 4220 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
829 can be fit into 750 0 times, resulting in a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 50783.04825
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 15:
When dividing 7500 by 829, we get 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 50783.0482509
Deduct 7461 from 7500 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 16:
390 divided by 829 is 0 with a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 50783.0482509
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final outcome is 50783.0482509, with a leftover of 3.9e-07.
