Let's divide 8238467 by 421
We want to figure out the number of times 8238467 can be divided by 421.

Let's proceed to step 1:
421 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 421

Advancing to step 2:
If we divide 82 by 421, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Bring next digit (3) of the dividend behind the 82 and repeat the process: 823 / 421

Step 3:
421 can be fit into 823 1 times, resulting in a remainder of 402.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 402 after subtracting 421 from 823.
Bring next digit (8) of the dividend behind the 402 and repeat the process: 4028 / 421

Step 4:
421 can be fit into 4028 9 times, resulting in a remainder of 239.
The next digit of our result is 9. 
Result so far: 19.0
If we take 3789 away from 4028, we end up with 239.
Include the next digit (4) from the dividend after 239, then repeat: 2394 / 421

Step 5:
2394 divided by 421 is 5 with a remainder of 289.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Subtracting 2105 from 2394 leaves us with 289.
Bring next digit (6) of the dividend behind the 289 and repeat the process: 2896 / 421

Going ahead to step 6:
When dividing 2896 by 421, we get 6 with a remainder of 370.
Use 6 as the next digit of our solution. 
Result so far: 1956.0
Subtract 2526 from 2896 to get 370.
Append the next digit (7) from the dividend to 370 and continue with: 3707 / 421

Going ahead to step 7:
421 can be fit into 3707 8 times, resulting in a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 19568.0
Subtracting 3368 from 3707 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 8:
421 can be fit into 3390 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 19568.8
If we take 3368 away from 3390, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 421, we get 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 19568.8
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
421 can be fit into 2200 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 19568.805
Subtracting 2105 from 2200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 11:
If we divide 950 by 421, we get 2 and a remainder of 108.
The next digit of our result is 2. 
Result so far: 19568.8052
If we take 842 away from 950, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 12:
421 goes into 1080 2 times with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 19568.80522
The remainder is 238 after subtracting 842 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final result is 19568.80522 with a remainder of 0.000238.
