We're dividing 40570323 by 838 
We want to divide 40570323 by 838.

Step 1:
If we divide 4 by 838, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 838

Going ahead to step 2:
838 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 838

Let's proceed to step 3:
If we divide 405 by 838, we get 0 and a remainder of 405.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 405 and we're left with 405.
Grab the next digit (7) from the dividend, add it to 405, then carry on: 4057 / 838

Let's proceed to step 4:
4057 divided by 838 is 4 with a remainder of 705.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3352 from 4057 and we're left with 705.
Include the next digit (0) from the dividend after 705, then repeat: 7050 / 838

Step 5:
838 can be fit into 7050 8 times, resulting in a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 346 after subtracting 6704 from 7050.
Fetch the next digit (3) from the dividend, attach it to 346 and continue: 3463 / 838

Let's proceed to step 6:
If we divide 3463 by 838, we get 4 and a remainder of 111.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
Subtracting 3352 from 3463 leaves us with 111.
Take the next digit (2) from the dividend and append it to 111, then repeat: 1112 / 838

Advancing to step 7:
838 goes into 1112 1 times with a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 4841.0
The remainder is 274 after subtracting 838 from 1112.
Fetch the next digit (3) from the dividend, attach it to 274 and continue: 2743 / 838

Step 8:
838 can be fit into 2743 3 times, resulting in a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 48413.0
If we subtract 2514 from 2743, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 9:
2290 divided by 838 is 2 with a remainder of 614.
Record the quotient 2 as the next digit in the result. 
Result so far: 48413.2
If we take 1676 away from 2290, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
If we divide 6140 by 838, we get 7 and a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 48413.27
The remainder is 274 after subtracting 5866 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 11:
2740 divided by 838 is 3 with a remainder of 226.
The next digit of our result is 3. 
Result so far: 48413.273
Subtracting 2514 from 2740 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 12:
838 can be fit into 2260 2 times, resulting in a remainder of 584.
The number 2 becomes the next digit in our result. 
Result so far: 48413.2732
The remainder is 584 after subtracting 1676 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 13:
If we divide 5840 by 838, we get 6 and a remainder of 812.
Use 6 as the next digit of our solution. 
Result so far: 48413.27326
If we subtract 5028 from 5840, we get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

On to step 14:
8120 divided by 838 is 9 with a remainder of 578.
Put 9 as the next digit of the answer. 
Result so far: 48413.273269
If we subtract 7542 from 8120, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 15:
The number 838 fits into 5780 6 times, leaving a remainder of 752.
The next digit of our result is 6. 
Result so far: 48413.2732696
If we take 5028 away from 5780, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 16:
If we divide 7520 by 838, we get 8 and a remainder of 816.
The next digit of our result is 8. 
Result so far: 48413.27326968
Deduct 6704 from 7520 and we're left with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

The final result is 48413.27326968 with a remainder of 8.16e-07.
