We divide 54860045 by 549
We're looking to find how many times 549 goes into 54860045.

Step 1:
549 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 549

On to step 2:
549 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 549

Advancing to step 3:
548 divided by 549 is 0 with a remainder of 548.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 548 after subtracting 0 from 548.
Take the next digit (6) from the dividend and append it to 548, then repeat: 5486 / 549

Going ahead to step 4:
549 can be fit into 5486 9 times, resulting in a remainder of 545.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 4941 from 5486 leaves us with 545.
Append the next digit (0) from the dividend to 545 and continue with: 5450 / 549

Step 5:
5450 divided by 549 is 9 with a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 4941 away from 5450, we end up with 509.
Take the next digit (0) from the dividend and append it to 509, then repeat: 5090 / 549

On to step 6:
If we divide 5090 by 549, we get 9 and a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
Subtracting 4941 from 5090 leaves us with 149.
Include the next digit (4) from the dividend after 149, then repeat: 1494 / 549

On to step 7:
1494 divided by 549 is 2 with a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 9992.0
Deduct 1098 from 1494 and we're left with 396.
Include the next digit (5) from the dividend after 396, then repeat: 3965 / 549

Step 8:
If we divide 3965 by 549, we get 7 and a remainder of 122.
The next digit of our result is 7. 
Result so far: 99927.0
Subtract 3843 from 3965 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 9:
1220 divided by 549 is 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 99927.2
If we take 1098 away from 1220, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
549 can be fit into 1220 2 times, resulting in a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 99927.22
If we take 1098 away from 1220, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final outcome is 99927.22, with a leftover of 0.122.
