We're dividing 49966399 by 781 
We want to figure out the number of times 49966399 can be divided by 781.

On to step 1:
4 divided by 781 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 781

Step 2:
781 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 781

Let's proceed to step 3:
When dividing 499 by 781, we get 0 with a remainder of 499.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 499 to get 499.
Fetch the next digit (6) from the dividend, attach it to 499 and continue: 4996 / 781

Step 4:
When dividing 4996 by 781, we get 6 with a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 4686 from 4996 leaves us with 310.
Append the next digit (6) from the dividend to 310 and continue with: 3106 / 781

Advancing to step 5:
3106 divided by 781 is 3 with a remainder of 763.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Deduct 2343 from 3106 and we're left with 763.
Append the next digit (3) from the dividend to 763 and continue with: 7633 / 781

Step 6:
7633 divided by 781 is 9 with a remainder of 604.
Use 9 as the next digit of our solution. 
Result so far: 639.0
The remainder is 604 after subtracting 7029 from 7633.
Bring next digit (9) of the dividend behind the 604 and repeat the process: 6049 / 781

Moving on to step 7:
If we divide 6049 by 781, we get 7 and a remainder of 582.
Put 7 as the next digit of the answer. 
Result so far: 6397.0
Subtracting 5467 from 6049 leaves us with 582.
Grab the next digit (9) from the dividend, add it to 582, then carry on: 5829 / 781

Going ahead to step 8:
If we divide 5829 by 781, we get 7 and a remainder of 362.
Record the quotient 7 as the next digit in the result. 
Result so far: 63977.0
If we take 5467 away from 5829, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 9:
The number 781 fits into 3620 4 times, leaving a remainder of 496.
The next digit of our result is 4. 
Result so far: 63977.4
If we subtract 3124 from 3620, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 10:
781 goes into 4960 6 times with a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 63977.46
The remainder is 274 after subtracting 4686 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 11:
781 goes into 2740 3 times with a remainder of 397.
The next digit of our result is 3. 
Result so far: 63977.463
Deduct 2343 from 2740 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 12:
781 goes into 3970 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 63977.4635
Subtracting 3905 from 3970 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
781 goes into 650 0 times with a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 63977.4635
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 14:
6500 divided by 781 is 8 with a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 63977.463508
If we subtract 6248 from 6500, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 15:
If we divide 2520 by 781, we get 3 and a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 63977.4635083
Subtracting 2343 from 2520 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 16:
The number 781 fits into 1770 2 times, leaving a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 63977.46350832
Subtract 1562 from 1770 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 63977.46350832 with a balance of 2.08e-07.
