We divide 40139553 by 409
We're looking to find how many times 409 goes into 40139553.

Step 1:
The number 409 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 409

Going ahead to step 2:
The number 409 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 409

Step 3:
409 goes into 401 0 times with a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Take the next digit (3) from the dividend and append it to 401, then repeat: 4013 / 409

Moving on to step 4:
When dividing 4013 by 409, we get 9 with a remainder of 332.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 3681 from 4013 to get 332.
Fetch the next digit (9) from the dividend, attach it to 332 and continue: 3329 / 409

Going ahead to step 5:
3329 divided by 409 is 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 3272 from 3329 and we're left with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 409

Going ahead to step 6:
409 can be fit into 575 1 times, resulting in a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 981.0
Deduct 409 from 575 and we're left with 166.
Fetch the next digit (5) from the dividend, attach it to 166 and continue: 1665 / 409

Step 7:
When dividing 1665 by 409, we get 4 with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 9814.0
Subtract 1636 from 1665 to get 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 409

On to step 8:
If we divide 293 by 409, we get 0 and a remainder of 293.
The next digit of our result is 0. 
Result so far: 98140.0
Subtracting 0 from 293 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 9:
2930 divided by 409 is 7 with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 98140.7
If we take 2863 away from 2930, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 10:
The number 409 fits into 670 1 times, leaving a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 98140.71
Deduct 409 from 670 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Let's proceed to step 11:
If we divide 2610 by 409, we get 6 and a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 98140.716
Subtract 2454 from 2610 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
If we divide 1560 by 409, we get 3 and a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 98140.7163
Deduct 1227 from 1560 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 13:
409 can be fit into 3330 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 98140.71638
If we subtract 3272 from 3330, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
If we divide 580 by 409, we get 1 and a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 98140.716381
If we take 409 away from 580, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 15:
If we divide 1710 by 409, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 98140.7163814
The remainder is 74 after subtracting 1636 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 16:
740 divided by 409 is 1 with a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 98140.71638141
Subtract 409 from 740 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The quotient of the division is 98140.71638141, and the remainder is 3.31e-07.
