Step 5:
The number 554 fits into 2995 5 times, leaving a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtract 2770 from 2995 to get 225.
Take the next digit (7) from the dividend and append it to 225, then repeat: 2257 / 554

Step 6:
2257 divided by 554 is 4 with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 1454.0
Subtract 2216 from 2257 to get 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 554

On to step 7:
The number 554 fits into 419 0 times, leaving a remainder of 419.
Write down 0 as next digit of the result. 
Result so far: 14540.0
Deduct 0 from 419 and we're left with 419.
Take the next digit (0) from the dividend and append it to 419, then repeat: 4190 / 554

Moving on to step 8:
4190 divided by 554 is 7 with a remainder of 312.
The next digit of our result is 7. 
Result so far: 145407.0
Deduct 3878 from 4190 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
The number 554 fits into 3120 5 times, leaving a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 145407.5
If we subtract 2770 from 3120, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
The number 554 fits into 3500 6 times, leaving a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 145407.56
Deduct 3324 from 3500 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
554 can be fit into 1760 3 times, resulting in a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 145407.563
Subtract 1662 from 1760 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 12:
If we divide 980 by 554, we get 1 and a remainder of 426.
The number 1 becomes the next digit in our result. 
Result so far: 145407.5631
Deduct 554 from 980 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 13:
554 goes into 4260 7 times with a remainder of 382.
Record the quotient 7 as the next digit in the result. 
Result so far: 145407.56317
If we subtract 3878 from 4260, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 14:
554 can be fit into 3820 6 times, resulting in a remainder of 496.
Write down 6 as next digit of the result. 
Result so far: 145407.563176
If we subtract 3324 from 3820, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 15:
When dividing 4960 by 554, we get 8 with a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 145407.5631768
Deduct 4432 from 4960 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 16:
554 can be fit into 5280 9 times, resulting in a remainder of 294.
Put 9 as the next digit of the answer. 
Result so far: 145407.56317689
The remainder is 294 after subtracting 4986 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The quotient of the division is 145407.56317689, and the remainder is 2.94e-07.
