Moving on to step 4:
1258 divided by 816 is 1 with a remainder of 442.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 816 from 1258 leaves us with 442.
Bring next digit (4) of the dividend behind the 442 and repeat the process: 4424 / 816

Step 5:
816 goes into 4424 5 times with a remainder of 344.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 4080 away from 4424, we end up with 344.
Include the next digit (0) from the dividend after 344, then repeat: 3440 / 816

Let's proceed to step 6:
816 goes into 3440 4 times with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 3264 from 3440, we get 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 816

Going ahead to step 7:
The number 816 fits into 1763 2 times, leaving a remainder of 131.
Write down 2 as next digit of the result. 
Result so far: 1542.0
If we subtract 1632 from 1763, we get 131.
Fetch the next digit (0) from the dividend, attach it to 131 and continue: 1310 / 816

Let's proceed to step 8:
816 goes into 1310 1 times with a remainder of 494.
Use 1 as the next digit of our solution. 
Result so far: 15421.0
The remainder is 494 after subtracting 816 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 9:
If we divide 4940 by 816, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 15421.6
Deduct 4896 from 4940 and we're left 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.

Step 10:
The number 816 fits into 440 0 times, leaving a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 15421.6
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
When dividing 4400 by 816, we get 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 15421.605
Deduct 4080 from 4400 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
3200 divided by 816 is 3 with a remainder of 752.
Record the quotient 3 as the next digit in the result. 
Result so far: 15421.6053
If we take 2448 away from 3200, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 13:
7520 divided by 816 is 9 with a remainder of 176.
The number 9 becomes the next digit in our result. 
Result so far: 15421.60539
The remainder is 176 after subtracting 7344 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 14:
When dividing 1760 by 816, we get 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 15421.605392
Deduct 1632 from 1760 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
816 goes into 1280 1 times with a remainder of 464.
Record the quotient 1 as the next digit in the result. 
Result so far: 15421.6053921
If we take 816 away from 1280, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 16:
The number 816 fits into 4640 5 times, leaving a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 15421.60539215
Deduct 4080 from 4640 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 15421.60539215 with a balance of 5.6e-07.
