16815848 divided by 458 
The aim is to understand the frequency of 458 in 16815848.

On to step 1:
458 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 458

Let's proceed to step 2:
If we divide 16 by 458, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 458

Let's proceed to step 3:
168 divided by 458 is 0 with a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Bring next digit (1) of the dividend behind the 168 and repeat the process: 1681 / 458

On to step 4:
458 goes into 1681 3 times with a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1374 away from 1681, we end up with 307.
Grab the next digit (5) from the dividend, add it to 307, then carry on: 3075 / 458

Step 5:
458 can be fit into 3075 6 times, resulting in a remainder of 327.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 2748 from 3075 leaves us with 327.
Take the next digit (8) from the dividend and append it to 327, then repeat: 3278 / 458

Step 6:
When dividing 3278 by 458, we get 7 with a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 367.0
The remainder is 72 after subtracting 3206 from 3278.
Include the next digit (4) from the dividend after 72, then repeat: 724 / 458

Step 7:
458 goes into 724 1 times with a remainder of 266.
The next digit of our result is 1. 
Result so far: 3671.0
The remainder is 266 after subtracting 458 from 724.
Grab the next digit (8) from the dividend, add it to 266, then carry on: 2668 / 458

Step 8:
2668 divided by 458 is 5 with a remainder of 378.
The number 5 becomes the next digit in our result. 
Result so far: 36715.0
If we take 2290 away from 2668, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 9:
458 goes into 3780 8 times with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 36715.8
If we subtract 3664 from 3780, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
The number 458 fits into 1160 2 times, leaving a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 36715.82
Subtract 916 from 1160 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
If we divide 2440 by 458, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 36715.825
The remainder is 150 after subtracting 2290 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
1500 divided by 458 is 3 with a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 36715.8253
If we subtract 1374 from 1500, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
1260 divided by 458 is 2 with a remainder of 344.
The next digit of our result is 2. 
Result so far: 36715.82532
The remainder is 344 after subtracting 916 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 14:
When dividing 3440 by 458, we get 7 with a remainder of 234.
Use 7 as the next digit of our solution. 
Result so far: 36715.825327
If we subtract 3206 from 3440, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 15:
If we divide 2340 by 458, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 36715.8253275
Subtract 2290 from 2340 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 16:
The number 458 fits into 500 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 36715.82532751
Subtracting 458 from 500 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 36715.82532751 with a balance of 4.2e-08.
