We're dividing 84649873 by 549 
We want to divide 84649873 by 549.

Going ahead to step 1:
If we divide 8 by 549, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 549

On to step 2:
The number 549 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 549

Step 3:
846 divided by 549 is 1 with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 549 away from 846, we end up with 297.
Fetch the next digit (4) from the dividend, attach it to 297 and continue: 2974 / 549

Step 4:
2974 divided by 549 is 5 with a remainder of 229.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2745 from 2974 and we're left with 229.
Append the next digit (9) from the dividend to 229 and continue with: 2299 / 549

Moving on to step 5:
If we divide 2299 by 549, we get 4 and a remainder of 103.
Write down 4 as next digit of the result. 
Result so far: 154.0
Deduct 2196 from 2299 and we're left with 103.
Append the next digit (8) from the dividend to 103 and continue with: 1038 / 549

Let's proceed to step 6:
The number 549 fits into 1038 1 times, leaving a remainder of 489.
Put 1 as the next digit of the answer. 
Result so far: 1541.0
If we subtract 549 from 1038, we get 489.
Bring next digit (7) of the dividend behind the 489 and repeat the process: 4897 / 549

Step 7:
4897 divided by 549 is 8 with a remainder of 505.
Use 8 as the next digit of our solution. 
Result so far: 15418.0
Subtracting 4392 from 4897 leaves us with 505.
Fetch the next digit (3) from the dividend, attach it to 505 and continue: 5053 / 549

On to step 8:
When dividing 5053 by 549, we get 9 with a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 154189.0
If we subtract 4941 from 5053, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
If we divide 1120 by 549, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 154189.2
The remainder is 22 after subtracting 1098 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
549 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 154189.2
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
549 can be fit into 2200 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 154189.204
Subtract 2196 from 2200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
549 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 154189.204
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 549, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 154189.204
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 154189.204 with a balance of 0.0004.
