The number 649 fits into 4315 6 times, leaving a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 3894 from 4315 to get 421.
Fetch the next digit (7) from the dividend, attach it to 421 and continue: 4217 / 649

Step 5:
4217 divided by 649 is 6 with a remainder of 323.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 3894 from 4217 to get 323.
Take the next digit (9) from the dividend and append it to 323, then repeat: 3239 / 649

On to step 6:
The number 649 fits into 3239 4 times, leaving a remainder of 643.
Write down 4 as next digit of the result. 
Result so far: 664.0
Deduct 2596 from 3239 and we're left with 643.
Grab the next digit (3) from the dividend, add it to 643, then carry on: 6433 / 649

On to step 7:
When dividing 6433 by 649, we get 9 with a remainder of 592.
Put 9 as the next digit of the answer. 
Result so far: 6649.0
Deduct 5841 from 6433 and we're left with 592.
Bring next digit (0) of the dividend behind the 592 and repeat the process: 5920 / 649

Step 8:
5920 divided by 649 is 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 66499.0
The remainder is 79 after subtracting 5841 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
790 divided by 649 is 1 with a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 66499.1
If we take 649 away from 790, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 10:
If we divide 1410 by 649, we get 2 and a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 66499.12
The remainder is 112 after subtracting 1298 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
The number 649 fits into 1120 1 times, leaving a remainder of 471.
The next digit of our result is 1. 
Result so far: 66499.121
The remainder is 471 after subtracting 649 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 12:
649 can be fit into 4710 7 times, resulting in a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 66499.1217
Deduct 4543 from 4710 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 13:
649 goes into 1670 2 times with a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 66499.12172
The remainder is 372 after subtracting 1298 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 14:
When dividing 3720 by 649, we get 5 with a remainder of 475.
The next digit of our result is 5. 
Result so far: 66499.121725
Deduct 3245 from 3720 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 15:
649 can be fit into 4750 7 times, resulting in a remainder of 207.
Write down 7 as next digit of the result. 
Result so far: 66499.1217257
Subtracting 4543 from 4750 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 16:
The number 649 fits into 2070 3 times, leaving a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 66499.12172573
Deduct 1947 from 2070 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Our division results in 66499.12172573 with a remaining 1.23e-07.
