We look at the division of 4787321 by 649 
Let's see how many times 649 fits into 4787321.

Let's proceed to step 1:
If we divide 4 by 649, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 649

Advancing to step 2:
The number 649 fits into 47 0 times, leaving a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 649

Advancing to step 3:
478 divided by 649 is 0 with a remainder of 478.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 478 leaves us with 478.
Bring next digit (7) of the dividend behind the 478 and repeat the process: 4787 / 649

Advancing to step 4:
649 can be fit into 4787 7 times, resulting in a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4543 from 4787, we get 244.
Grab the next digit (3) from the dividend, add it to 244, then carry on: 2443 / 649

On to step 5:
649 goes into 2443 3 times with a remainder of 496.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 1947 from 2443 to get 496.
Bring next digit (2) of the dividend behind the 496 and repeat the process: 4962 / 649

Moving on to step 6:
4962 divided by 649 is 7 with a remainder of 419.
Write down 7 as next digit of the result. 
Result so far: 737.0
Subtract 4543 from 4962 to get 419.
Bring next digit (1) of the dividend behind the 419 and repeat the process: 4191 / 649

Advancing to step 7:
The number 649 fits into 4191 6 times, leaving a remainder of 297.
Write down 6 as next digit of the result. 
Result so far: 7376.0
If we subtract 3894 from 4191, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 8:
649 can be fit into 2970 4 times, resulting in a remainder of 374.
Put 4 as the next digit of the answer. 
Result so far: 7376.4
If we take 2596 away from 2970, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 9:
The number 649 fits into 3740 5 times, leaving a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 7376.45
Deduct 3245 from 3740 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 10:
If we divide 4950 by 649, we get 7 and a remainder of 407.
The next digit of our result is 7. 
Result so far: 7376.457
Subtract 4543 from 4950 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 11:
649 goes into 4070 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 7376.4576
Subtract 3894 from 4070 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 12:
If we divide 1760 by 649, we get 2 and a remainder of 462.
The number 2 becomes the next digit in our result. 
Result so far: 7376.45762
Deduct 1298 from 1760 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 13:
If we divide 4620 by 649, we get 7 and a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 7376.457627
Deduct 4543 from 4620 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 14:
649 can be fit into 770 1 times, resulting in a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 7376.4576271
The remainder is 121 after subtracting 649 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 15:
649 goes into 1210 1 times with a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 7376.45762711
The remainder is 561 after subtracting 649 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

The final outcome is 7376.45762711, with a leftover of 5.61e-07.
