We divide 40509943 by 408
Let's see how many times 408 fits into 40509943.

Let's proceed to step 1:
If we divide 4 by 408, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 408

Step 2:
When dividing 40 by 408, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 408

On to step 3:
405 divided by 408 is 0 with a remainder of 405.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 405 after subtracting 0 from 405.
Take the next digit (0) from the dividend and append it to 405, then repeat: 4050 / 408

On to step 4:
When dividing 4050 by 408, we get 9 with a remainder of 378.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 3672 from 4050 to get 378.
Append the next digit (9) from the dividend to 378 and continue with: 3789 / 408

Let's proceed to step 5:
When dividing 3789 by 408, we get 9 with a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 3672 from 3789 to get 117.
Fetch the next digit (9) from the dividend, attach it to 117 and continue: 1179 / 408

Going ahead to step 6:
When dividing 1179 by 408, we get 2 with a remainder of 363.
The next digit of our result is 2. 
Result so far: 992.0
Subtracting 816 from 1179 leaves us with 363.
Bring next digit (4) of the dividend behind the 363 and repeat the process: 3634 / 408

Advancing to step 7:
408 can be fit into 3634 8 times, resulting in a remainder of 370.
The next digit of our result is 8. 
Result so far: 9928.0
The remainder is 370 after subtracting 3264 from 3634.
Include the next digit (3) from the dividend after 370, then repeat: 3703 / 408

Let's proceed to step 8:
408 can be fit into 3703 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 99289.0
Deduct 3672 from 3703 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
If we divide 310 by 408, we get 0 and a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 99289.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
408 goes into 3100 7 times with a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 99289.07
The remainder is 244 after subtracting 2856 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
The number 408 fits into 2440 5 times, leaving a remainder of 400.
The next digit of our result is 5. 
Result so far: 99289.075
If we take 2040 away from 2440, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 408, we get 9 with a remainder of 328.
The next digit of our result is 9. 
Result so far: 99289.0759
If we subtract 3672 from 4000, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 13:
408 goes into 3280 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 99289.07598
If we subtract 3264 from 3280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 408 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 99289.07598
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
408 goes into 1600 3 times with a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 99289.0759803
If we take 1224 away from 1600, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
The number 408 fits into 3760 9 times, leaving a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 99289.07598039
Subtracting 3672 from 3760 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 99289.07598039 and a remainder of 8.8e-08.
