On to step 3:
217 divided by 554 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Grab the next digit (0) from the dividend, add it to 217, then carry on: 2170 / 554

Advancing to step 4:
2170 divided by 554 is 3 with a remainder of 508.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1662 away from 2170, we end up with 508.
Take the next digit (8) from the dividend and append it to 508, then repeat: 5088 / 554

Moving on to step 5:
5088 divided by 554 is 9 with a remainder of 102.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 4986 from 5088 to get 102.
Fetch the next digit (7) from the dividend, attach it to 102 and continue: 1027 / 554

Advancing to step 6:
When dividing 1027 by 554, we get 1 with a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 391.0
Subtracting 554 from 1027 leaves us with 473.
Take the next digit (6) from the dividend and append it to 473, then repeat: 4736 / 554

Going ahead to step 7:
4736 divided by 554 is 8 with a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 3918.0
Subtract 4432 from 4736 to get 304.
Append the next digit (0) from the dividend to 304 and continue with: 3040 / 554

Advancing to step 8:
554 can be fit into 3040 5 times, resulting in a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 39185.0
Subtract 2770 from 3040 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 9:
The number 554 fits into 2700 4 times, leaving a remainder of 484.
Record the quotient 4 as the next digit in the result. 
Result so far: 39185.4
The remainder is 484 after subtracting 2216 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 10:
If we divide 4840 by 554, we get 8 and a remainder of 408.
The next digit of our result is 8. 
Result so far: 39185.48
Subtract 4432 from 4840 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 11:
The number 554 fits into 4080 7 times, leaving a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 39185.487
Subtract 3878 from 4080 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 12:
554 can be fit into 2020 3 times, resulting in a remainder of 358.
Record the quotient 3 as the next digit in the result. 
Result so far: 39185.4873
Deduct 1662 from 2020 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 13:
If we divide 3580 by 554, we get 6 and a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 39185.48736
If we take 3324 away from 3580, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
If we divide 2560 by 554, we get 4 and a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 39185.487364
Subtracting 2216 from 2560 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 15:
3440 divided by 554 is 6 with a remainder of 116.
The next digit of our result is 6. 
Result so far: 39185.4873646
The remainder is 116 after subtracting 3324 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 16:
554 goes into 1160 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 39185.48736462
If we take 1108 away from 1160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 39185.48736462 and a remainder of 5.2e-08.
