Step 3:
649 can be fit into 545 0 times, resulting in a remainder of 545.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 545 to get 545.
Bring next digit (8) of the dividend behind the 545 and repeat the process: 5458 / 649

Let's proceed to step 4:
649 goes into 5458 8 times with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5192 from 5458 to get 266.
Take the next digit (6) from the dividend and append it to 266, then repeat: 2666 / 649

Moving on to step 5:
649 can be fit into 2666 4 times, resulting in a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 2596 from 2666 and we're left with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 649

Moving on to step 6:
649 can be fit into 709 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 841.0
The remainder is 60 after subtracting 649 from 709.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 649

On to step 7:
649 can be fit into 606 0 times, resulting in a remainder of 606.
The number 0 becomes the next digit in our result. 
Result so far: 8410.0
Subtracting 0 from 606 leaves us with 606.
Fetch the next digit (3) from the dividend, attach it to 606 and continue: 6063 / 649

Going ahead to step 8:
649 goes into 6063 9 times with a remainder of 222.
The next digit of our result is 9. 
Result so far: 84109.0
Subtracting 5841 from 6063 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 9:
2220 divided by 649 is 3 with a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 84109.3
Subtract 1947 from 2220 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 10:
2730 divided by 649 is 4 with a remainder of 134.
The next digit of our result is 4. 
Result so far: 84109.34
Subtracting 2596 from 2730 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 11:
1340 divided by 649 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 84109.342
Subtracting 1298 from 1340 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
649 goes into 420 0 times with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 84109.342
The remainder is 420 after subtracting 0 from 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 13:
4200 divided by 649 is 6 with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 84109.34206
If we take 3894 away from 4200, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 14:
If we divide 3060 by 649, we get 4 and a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 84109.342064
Deduct 2596 from 3060 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 15:
When dividing 4640 by 649, we get 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 84109.3420647
If we subtract 4543 from 4640, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 16:
970 divided by 649 is 1 with a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 84109.34206471
If we take 649 away from 970, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

The quotient of the division is 84109.34206471, and the remainder is 3.21e-07.
