Let's divide 99705903 by 781
We want to figure out the number of times 99705903 can be divided by 781.

On to step 1:
9 divided by 781 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 781

On to step 2:
781 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 781

Step 3:
781 can be fit into 997 1 times, resulting in a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 781 from 997 leaves us with 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 781

Moving on to step 4:
781 goes into 2160 2 times with a remainder of 598.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1562 from 2160 leaves us with 598.
Bring next digit (5) of the dividend behind the 598 and repeat the process: 5985 / 781

Moving on to step 5:
The number 781 fits into 5985 7 times, leaving a remainder of 518.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 518 after subtracting 5467 from 5985.
Grab the next digit (9) from the dividend, add it to 518, then carry on: 5189 / 781

Moving on to step 6:
781 goes into 5189 6 times with a remainder of 503.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
If we take 4686 away from 5189, we end up with 503.
Grab the next digit (0) from the dividend, add it to 503, then carry on: 5030 / 781

On to step 7:
5030 divided by 781 is 6 with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 12766.0
Subtract 4686 from 5030 to get 344.
Take the next digit (3) from the dividend and append it to 344, then repeat: 3443 / 781

On to step 8:
The number 781 fits into 3443 4 times, leaving a remainder of 319.
The number 4 becomes the next digit in our result. 
Result so far: 127664.0
Deduct 3124 from 3443 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 9:
781 goes into 3190 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 127664.4
If we take 3124 away from 3190, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
If we divide 660 by 781, we get 0 and a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 127664.4
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 11:
The number 781 fits into 6600 8 times, leaving a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 127664.408
If we take 6248 away from 6600, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 12:
3520 divided by 781 is 4 with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 127664.4084
Deduct 3124 from 3520 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 13:
If we divide 3960 by 781, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 127664.40845
Subtracting 3905 from 3960 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
If we divide 550 by 781, we get 0 and a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 127664.40845
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 15:
781 can be fit into 5500 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 127664.4084507
Deduct 5467 from 5500 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 16:
781 can be fit into 330 0 times, resulting in a remainder of 330.
The next digit of our result is 0. 
Result so far: 127664.4084507
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Our division results in 127664.4084507 with a remaining 3.3e-07.
