Deduct 1098 from 1632 and we're left with 534.
Fetch the next digit (9) from the dividend, attach it to 534 and continue: 5349 / 549

Moving on to step 5:
If we divide 5349 by 549, we get 9 and a remainder of 408.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 4941 from 5349 leaves us with 408.
Fetch the next digit (3) from the dividend, attach it to 408 and continue: 4083 / 549

Let's proceed to step 6:
4083 divided by 549 is 7 with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 297.0
If we subtract 3843 from 4083, we get 240.
Include the next digit (2) from the dividend after 240, then repeat: 2402 / 549

Let's proceed to step 7:
549 goes into 2402 4 times with a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 2974.0
Subtracting 2196 from 2402 leaves us with 206.
Append the next digit (7) from the dividend to 206 and continue with: 2067 / 549

Advancing to step 8:
2067 divided by 549 is 3 with a remainder of 420.
Write down 3 as next digit of the result. 
Result so far: 29743.0
Subtracting 1647 from 2067 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 9:
If we divide 4200 by 549, we get 7 and a remainder of 357.
Write down 7 as next digit of the result. 
Result so far: 29743.7
The remainder is 357 after subtracting 3843 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 10:
The number 549 fits into 3570 6 times, leaving a remainder of 276.
Use 6 as the next digit of our solution. 
Result so far: 29743.76
If we subtract 3294 from 3570, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
2760 divided by 549 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 29743.765
Deduct 2745 from 2760 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
549 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 29743.765
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 13:
When dividing 1500 by 549, we get 2 with a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 29743.76502
The remainder is 402 after subtracting 1098 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 14:
If we divide 4020 by 549, we get 7 and a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 29743.765027
Deduct 3843 from 4020 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 15:
When dividing 1770 by 549, we get 3 with a remainder of 123.
Write down 3 as next digit of the result. 
Result so far: 29743.7650273
The remainder is 123 after subtracting 1647 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 16:
1230 divided by 549 is 2 with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 29743.76502732
If we take 1098 away from 1230, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.
