99400343 ÷ 823 
We want to figure out the number of times 99400343 can be divided by 823.

Going ahead to step 1:
823 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 823

Going ahead to step 2:
If we divide 99 by 823, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 823

Let's proceed to step 3:
The number 823 fits into 994 1 times, leaving a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 823 away from 994, we end up with 171.
Bring next digit (0) of the dividend behind the 171 and repeat the process: 1710 / 823

On to step 4:
823 can be fit into 1710 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1646 away from 1710, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 823

Step 5:
If we divide 640 by 823, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtract 0 from 640 to get 640.
Include the next digit (3) from the dividend after 640, then repeat: 6403 / 823

Moving on to step 6:
The number 823 fits into 6403 7 times, leaving a remainder of 642.
Put 7 as the next digit of the answer. 
Result so far: 1207.0
Subtract 5761 from 6403 to get 642.
Append the next digit (4) from the dividend to 642 and continue with: 6424 / 823

Going ahead to step 7:
When dividing 6424 by 823, we get 7 with a remainder of 663.
The number 7 becomes the next digit in our result. 
Result so far: 12077.0
Subtract 5761 from 6424 to get 663.
Take the next digit (3) from the dividend and append it to 663, then repeat: 6633 / 823

Let's proceed to step 8:
6633 divided by 823 is 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 120778.0
The remainder is 49 after subtracting 6584 from 6633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 823 is 0 with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 120778.0
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 10:
The number 823 fits into 4900 5 times, leaving a remainder of 785.
Use 5 as the next digit of our solution. 
Result so far: 120778.05
Deduct 4115 from 4900 and we're left with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Step 11:
The number 823 fits into 7850 9 times, leaving a remainder of 443.
Use 9 as the next digit of our solution. 
Result so far: 120778.059
Subtract 7407 from 7850 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 12:
The number 823 fits into 4430 5 times, leaving a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 120778.0595
Subtracting 4115 from 4430 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 13:
If we divide 3150 by 823, we get 3 and a remainder of 681.
Put 3 as the next digit of the answer. 
Result so far: 120778.05953
Deduct 2469 from 3150 and we're left with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Let's proceed to step 14:
823 can be fit into 6810 8 times, resulting in a remainder of 226.
The number 8 becomes the next digit in our result. 
Result so far: 120778.059538
The remainder is 226 after subtracting 6584 from 6810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 15:
If we divide 2260 by 823, we get 2 and a remainder of 614.
The number 2 becomes the next digit in our result. 
Result so far: 120778.0595382
The remainder is 614 after subtracting 1646 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 16:
When dividing 6140 by 823, we get 7 with a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 120778.05953827
Subtract 5761 from 6140 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Our division results in 120778.05953827 with a remaining 3.79e-07.
