Step 3:
554 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 250, we get 250.
Take the next digit (6) from the dividend and append it to 250, then repeat: 2506 / 554

Going ahead to step 4:
When dividing 2506 by 554, we get 4 with a remainder of 290.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 290 after subtracting 2216 from 2506.
Include the next digit (0) from the dividend after 290, then repeat: 2900 / 554

Step 5:
The number 554 fits into 2900 5 times, leaving a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 2770 from 2900 leaves us with 130.
Append the next digit (0) from the dividend to 130 and continue with: 1300 / 554

Going ahead to step 6:
When dividing 1300 by 554, we get 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 452.0
If we take 1108 away from 1300, we end up with 192.
Grab the next digit (2) from the dividend, add it to 192, then carry on: 1922 / 554

Moving on to step 7:
554 goes into 1922 3 times with a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 4523.0
Subtracting 1662 from 1922 leaves us with 260.
Grab the next digit (1) from the dividend, add it to 260, then carry on: 2601 / 554

Let's proceed to step 8:
When dividing 2601 by 554, we get 4 with a remainder of 385.
Write down 4 as next digit of the result. 
Result so far: 45234.0
Subtracting 2216 from 2601 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 9:
554 can be fit into 3850 6 times, resulting in a remainder of 526.
The number 6 becomes the next digit in our result. 
Result so far: 45234.6
Subtracting 3324 from 3850 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 10:
554 goes into 5260 9 times with a remainder of 274.
Write down 9 as next digit of the result. 
Result so far: 45234.69
Deduct 4986 from 5260 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 11:
The number 554 fits into 2740 4 times, leaving a remainder of 524.
Put 4 as the next digit of the answer. 
Result so far: 45234.694
Deduct 2216 from 2740 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 12:
If we divide 5240 by 554, we get 9 and a remainder of 254.
The next digit of our result is 9. 
Result so far: 45234.6949
Deduct 4986 from 5240 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 13:
554 goes into 2540 4 times with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 45234.69494
Deduct 2216 from 2540 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 14:
554 goes into 3240 5 times with a remainder of 470.
The next digit of our result is 5. 
Result so far: 45234.694945
Deduct 2770 from 3240 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 15:
The number 554 fits into 4700 8 times, leaving a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 45234.6949458
If we take 4432 away from 4700, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 16:
When dividing 2680 by 554, we get 4 with a remainder of 464.
Write down 4 as next digit of the result. 
Result so far: 45234.69494584
Subtract 2216 from 2680 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 45234.69494584, with a leftover of 4.64e-07.
