We divide 40004453 by 409
We're looking to find how many times 409 goes into 40004453.

On to step 1:
When dividing 4 by 409, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 409

On to step 2:
If we divide 40 by 409, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 409

Advancing to step 3:
400 divided by 409 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 400 leaves us with 400.
Include the next digit (0) from the dividend after 400, then repeat: 4000 / 409

Advancing to step 4:
The number 409 fits into 4000 9 times, leaving a remainder of 319.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 3681 from 4000 and we're left with 319.
Take the next digit (4) from the dividend and append it to 319, then repeat: 3194 / 409

Step 5:
3194 divided by 409 is 7 with a remainder of 331.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Deduct 2863 from 3194 and we're left with 331.
Grab the next digit (4) from the dividend, add it to 331, then carry on: 3314 / 409

Moving on to step 6:
3314 divided by 409 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 978.0
Deduct 3272 from 3314 and we're left with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 409

Step 7:
When dividing 425 by 409, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 9781.0
If we subtract 409 from 425, we get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 409

Advancing to step 8:
409 can be fit into 163 0 times, resulting in a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 97810.0
Subtracting 0 from 163 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 9:
409 goes into 1630 3 times with a remainder of 403.
The next digit of our result is 3. 
Result so far: 97810.3
Subtracting 1227 from 1630 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 10:
The number 409 fits into 4030 9 times, leaving a remainder of 349.
Put 9 as the next digit of the answer. 
Result so far: 97810.39
Deduct 3681 from 4030 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 11:
409 goes into 3490 8 times with a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 97810.398
Subtracting 3272 from 3490 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 12:
When dividing 2180 by 409, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 97810.3985
If we take 2045 away from 2180, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 13:
If we divide 1350 by 409, we get 3 and a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 97810.39853
If we subtract 1227 from 1350, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 14:
If we divide 1230 by 409, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 97810.398533
The remainder is 3 after subtracting 1227 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 97810.398533 with a remainder of 3e-07.
