We look at the division of 45963939 by 649 
Let's see how many times 649 fits into 45963939.

Step 1:
The number 649 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 649

Going ahead to step 2:
45 divided by 649 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 649

On to step 3:
If we divide 459 by 649, we get 0 and a remainder of 459.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 459, we end up with 459.
Bring next digit (6) of the dividend behind the 459 and repeat the process: 4596 / 649

Step 4:
649 can be fit into 4596 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4543 from 4596, we get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 649

Moving on to step 5:
649 goes into 533 0 times with a remainder of 533.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 533 after subtracting 0 from 533.
Append the next digit (9) from the dividend to 533 and continue with: 5339 / 649

Going ahead to step 6:
649 goes into 5339 8 times with a remainder of 147.
Record the quotient 8 as the next digit in the result. 
Result so far: 708.0
Deduct 5192 from 5339 and we're left with 147.
Append the next digit (3) from the dividend to 147 and continue with: 1473 / 649

Going ahead to step 7:
1473 divided by 649 is 2 with a remainder of 175.
The number 2 becomes the next digit in our result. 
Result so far: 7082.0
If we subtract 1298 from 1473, we get 175.
Append the next digit (9) from the dividend to 175 and continue with: 1759 / 649

Step 8:
If we divide 1759 by 649, we get 2 and a remainder of 461.
The number 2 becomes the next digit in our result. 
Result so far: 70822.0
Subtracting 1298 from 1759 leaves us with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Moving on to step 9:
649 can be fit into 4610 7 times, resulting in a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 70822.7
Subtract 4543 from 4610 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
When dividing 670 by 649, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 70822.71
Deduct 649 from 670 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
The number 649 fits into 210 0 times, leaving a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 70822.71
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
The number 649 fits into 2100 3 times, leaving a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 70822.7103
Subtracting 1947 from 2100 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 13:
649 can be fit into 1530 2 times, resulting in a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 70822.71032
The remainder is 232 after subtracting 1298 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 14:
2320 divided by 649 is 3 with a remainder of 373.
Put 3 as the next digit of the answer. 
Result so far: 70822.710323
The remainder is 373 after subtracting 1947 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 15:
649 can be fit into 3730 5 times, resulting in a remainder of 485.
The next digit of our result is 5. 
Result so far: 70822.7103235
Subtracting 3245 from 3730 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 16:
4850 divided by 649 is 7 with a remainder of 307.
Use 7 as the next digit of our solution. 
Result so far: 70822.71032357
If we take 4543 away from 4850, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The final result is 70822.71032357 with a remainder of 3.07e-07.
