Let's divide 63830400 by 458
The aim is to understand the frequency of 458 in 63830400.

Advancing to step 1:
458 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 458

Let's proceed to step 2:
If we divide 63 by 458, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 458

Step 3:
458 goes into 638 1 times with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 458 from 638 to get 180.
Fetch the next digit (3) from the dividend, attach it to 180 and continue: 1803 / 458

Step 4:
458 goes into 1803 3 times with a remainder of 429.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1374 from 1803 leaves us with 429.
Include the next digit (0) from the dividend after 429, then repeat: 4290 / 458

Advancing to step 5:
458 goes into 4290 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 4122 from 4290 and we're left with 168.
Grab the next digit (4) from the dividend, add it to 168, then carry on: 1684 / 458

Moving on to step 6:
1684 divided by 458 is 3 with a remainder of 310.
Use 3 as the next digit of our solution. 
Result so far: 1393.0
If we take 1374 away from 1684, we end up with 310.
Bring next digit (0) of the dividend behind the 310 and repeat the process: 3100 / 458

Going ahead to step 7:
458 can be fit into 3100 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 13936.0
If we subtract 2748 from 3100, we get 352.
Take the next digit (0) from the dividend and append it to 352, then repeat: 3520 / 458

Going ahead to step 8:
458 goes into 3520 7 times with a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 139367.0
If we take 3206 away from 3520, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
The number 458 fits into 3140 6 times, leaving a remainder of 392.
The next digit of our result is 6. 
Result so far: 139367.6
Deduct 2748 from 3140 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
When dividing 3920 by 458, we get 8 with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 139367.68
Deduct 3664 from 3920 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 11:
2560 divided by 458 is 5 with a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 139367.685
Deduct 2290 from 2560 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 12:
If we divide 2700 by 458, we get 5 and a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 139367.6855
Subtract 2290 from 2700 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The quotient of the division is 139367.6855, and the remainder is 0.0041.
