Let's divide 3935413 by 824
The aim is to understand the frequency of 824 in 3935413.

Let's proceed to step 1:
When dividing 3 by 824, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 824

Advancing to step 2:
When dividing 39 by 824, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 824

On to step 3:
824 goes into 393 0 times with a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 393 leaves us with 393.
Grab the next digit (5) from the dividend, add it to 393, then carry on: 3935 / 824

Step 4:
3935 divided by 824 is 4 with a remainder of 639.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 3296 from 3935, we get 639.
Fetch the next digit (4) from the dividend, attach it to 639 and continue: 6394 / 824

On to step 5:
If we divide 6394 by 824, we get 7 and a remainder of 626.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 5768 away from 6394, we end up with 626.
Take the next digit (1) from the dividend and append it to 626, then repeat: 6261 / 824

Let's proceed to step 6:
6261 divided by 824 is 7 with a remainder of 493.
Put 7 as the next digit of the answer. 
Result so far: 477.0
If we take 5768 away from 6261, we end up with 493.
Fetch the next digit (3) from the dividend, attach it to 493 and continue: 4933 / 824

Let's proceed to step 7:
824 can be fit into 4933 5 times, resulting in a remainder of 813.
The number 5 becomes the next digit in our result. 
Result so far: 4775.0
If we subtract 4120 from 4933, we get 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

On to step 8:
824 goes into 8130 9 times with a remainder of 714.
Use 9 as the next digit of our solution. 
Result so far: 4775.9
If we subtract 7416 from 8130, we get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 9:
The number 824 fits into 7140 8 times, leaving a remainder of 548.
Use 8 as the next digit of our solution. 
Result so far: 4775.98
Deduct 6592 from 7140 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
824 can be fit into 5480 6 times, resulting in a remainder of 536.
Use 6 as the next digit of our solution. 
Result so far: 4775.986
Subtracting 4944 from 5480 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 11:
When dividing 5360 by 824, we get 6 with a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 4775.9866
Subtract 4944 from 5360 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 4775.9866 with a remaining 0.00416.
