21039722 ÷ 829 
The aim is to understand the frequency of 829 in 21039722.

Going ahead to step 1:
If we divide 2 by 829, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 829

Let's proceed to step 2:
If we divide 21 by 829, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 829

Advancing to step 3:
The number 829 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Take the next digit (3) from the dividend and append it to 210, then repeat: 2103 / 829

Going ahead to step 4:
When dividing 2103 by 829, we get 2 with a remainder of 445.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1658 from 2103 to get 445.
Bring next digit (9) of the dividend behind the 445 and repeat the process: 4459 / 829

On to step 5:
829 can be fit into 4459 5 times, resulting in a remainder of 314.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 4145 from 4459, we get 314.
Bring next digit (7) of the dividend behind the 314 and repeat the process: 3147 / 829

On to step 6:
The number 829 fits into 3147 3 times, leaving a remainder of 660.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
The remainder is 660 after subtracting 2487 from 3147.
Grab the next digit (2) from the dividend, add it to 660, then carry on: 6602 / 829

Going ahead to step 7:
829 goes into 6602 7 times with a remainder of 799.
Record the quotient 7 as the next digit in the result. 
Result so far: 2537.0
Subtract 5803 from 6602 to get 799.
Grab the next digit (2) from the dividend, add it to 799, then carry on: 7992 / 829

Advancing to step 8:
7992 divided by 829 is 9 with a remainder of 531.
The next digit of our result is 9. 
Result so far: 25379.0
The remainder is 531 after subtracting 7461 from 7992.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 9:
5310 divided by 829 is 6 with a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 25379.6
Subtract 4974 from 5310 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
829 can be fit into 3360 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 25379.64
Subtracting 3316 from 3360 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
829 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 25379.64
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
If we divide 4400 by 829, we get 5 and a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 25379.6405
Subtracting 4145 from 4400 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 13:
829 can be fit into 2550 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 25379.64053
If we take 2487 away from 2550, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 14:
If we divide 630 by 829, we get 0 and a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 25379.64053
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 15:
The number 829 fits into 6300 7 times, leaving a remainder of 497.
Write down 7 as next digit of the result. 
Result so far: 25379.6405307
The remainder is 497 after subtracting 5803 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 16:
4970 divided by 829 is 5 with a remainder of 825.
Use 5 as the next digit of our solution. 
Result so far: 25379.64053075
If we take 4145 away from 4970, we end up with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

The quotient of the division is 25379.64053075, and the remainder is 8.25e-07.
