Let's divide 65390087 by 457
The aim is to understand the frequency of 457 in 65390087.

Step 1:
6 divided by 457 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 457

On to step 2:
457 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 457

Let's proceed to step 3:
If we divide 653 by 457, we get 1 and a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 457 from 653 and we're left with 196.
Include the next digit (9) from the dividend after 196, then repeat: 1969 / 457

Advancing to step 4:
If we divide 1969 by 457, we get 4 and a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1828 from 1969 and we're left with 141.
Append the next digit (0) from the dividend to 141 and continue with: 1410 / 457

On to step 5:
457 goes into 1410 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 143.0
Subtract 1371 from 1410 to get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 457

Moving on to step 6:
390 divided by 457 is 0 with a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 1430.0
If we take 0 away from 390, we end up with 390.
Bring next digit (8) of the dividend behind the 390 and repeat the process: 3908 / 457

On to step 7:
3908 divided by 457 is 8 with a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 14308.0
Subtract 3656 from 3908 to get 252.
Append the next digit (7) from the dividend to 252 and continue with: 2527 / 457

On to step 8:
The number 457 fits into 2527 5 times, leaving a remainder of 242.
The number 5 becomes the next digit in our result. 
Result so far: 143085.0
If we take 2285 away from 2527, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 9:
If we divide 2420 by 457, we get 5 and a remainder of 135.
The next digit of our result is 5. 
Result so far: 143085.5
Deduct 2285 from 2420 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
1350 divided by 457 is 2 with a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 143085.52
Subtracting 914 from 1350 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 11:
If we divide 4360 by 457, we get 9 and a remainder of 247.
Use 9 as the next digit of our solution. 
Result so far: 143085.529
If we take 4113 away from 4360, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 12:
2470 divided by 457 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 143085.5295
Deduct 2285 from 2470 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 13:
The number 457 fits into 1850 4 times, leaving a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 143085.52954
If we subtract 1828 from 1850, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
220 divided by 457 is 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 143085.52954
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
When dividing 2200 by 457, we get 4 with a remainder of 372.
Record the quotient 4 as the next digit in the result. 
Result so far: 143085.5295404
The remainder is 372 after subtracting 1828 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 16:
457 goes into 3720 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 143085.52954048
The remainder is 64 after subtracting 3656 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 143085.52954048 with a balance of 6.4e-08.
