87039533 ÷ 549 
Let's see how many times 549 fits into 87039533.

Going ahead to step 1:
The number 549 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 549

Advancing to step 2:
549 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 549

Advancing to step 3:
870 divided by 549 is 1 with a remainder of 321.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 549 from 870, we get 321.
Bring next digit (3) of the dividend behind the 321 and repeat the process: 3213 / 549

Advancing to step 4:
If we divide 3213 by 549, we get 5 and a remainder of 468.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2745 from 3213 leaves us with 468.
Include the next digit (9) from the dividend after 468, then repeat: 4689 / 549

Moving on to step 5:
4689 divided by 549 is 8 with a remainder of 297.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtract 4392 from 4689 to get 297.
Fetch the next digit (5) from the dividend, attach it to 297 and continue: 2975 / 549

Step 6:
549 goes into 2975 5 times with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 1585.0
If we subtract 2745 from 2975, we get 230.
Fetch the next digit (3) from the dividend, attach it to 230 and continue: 2303 / 549

Let's proceed to step 7:
The number 549 fits into 2303 4 times, leaving a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 15854.0
If we subtract 2196 from 2303, we get 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 549

Advancing to step 8:
1073 divided by 549 is 1 with a remainder of 524.
Use 1 as the next digit of our solution. 
Result so far: 158541.0
If we take 549 away from 1073, we end up 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.

Step 9:
549 goes into 5240 9 times with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 158541.9
The remainder is 299 after subtracting 4941 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 10:
When dividing 2990 by 549, we get 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 158541.95
The remainder is 245 after subtracting 2745 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 11:
549 can be fit into 2450 4 times, resulting in a remainder of 254.
The next digit of our result is 4. 
Result so far: 158541.954
Subtract 2196 from 2450 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 12:
The number 549 fits into 2540 4 times, leaving a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 158541.9544
If we subtract 2196 from 2540, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 158541.9544, with a leftover of 0.00344.
