We're dividing 12223409 by 291 
Let's see how many times 291 fits into 12223409.

Advancing to step 1:
291 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 291

On to step 2:
291 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 291

Moving on to step 3:
The number 291 fits into 122 0 times, leaving a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 291

Going ahead to step 4:
If we divide 1222 by 291, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1164 from 1222, we get 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 291

On to step 5:
When dividing 583 by 291, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 582 away from 583, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 291

Advancing to step 6:
When dividing 14 by 291, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 420.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 291

Advancing to step 7:
140 divided by 291 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 4200.0
The remainder is 140 after subtracting 0 from 140.
Append the next digit (9) from the dividend to 140 and continue with: 1409 / 291

Let's proceed to step 8:
The number 291 fits into 1409 4 times, leaving a remainder of 245.
Use 4 as the next digit of our solution. 
Result so far: 42004.0
If we take 1164 away from 1409, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 9:
2450 divided by 291 is 8 with a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 42004.8
Subtract 2328 from 2450 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
The number 291 fits into 1220 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 42004.84
If we take 1164 away from 1220, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 291, we get 1 and a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 42004.841
If we subtract 291 from 560, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 12:
The number 291 fits into 2690 9 times, leaving a remainder of 71.
The next digit of our result is 9. 
Result so far: 42004.8419
If we take 2619 away from 2690, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
291 goes into 710 2 times with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 42004.84192
The remainder is 128 after subtracting 582 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
The number 291 fits into 1280 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 42004.841924
If we subtract 1164 from 1280, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 15:
When dividing 1160 by 291, we get 3 with a remainder of 287.
The next digit of our result is 3. 
Result so far: 42004.8419243
If we subtract 873 from 1160, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 16:
291 can be fit into 2870 9 times, resulting in a remainder of 251.
The next digit of our result is 9. 
Result so far: 42004.84192439
The remainder is 251 after subtracting 2619 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

After the division, we end up with 42004.84192439 and a remainder of 2.51e-07.
