8558142 ÷ 413 
Our goal is to divide 8558142 by 413.

Moving on to step 1:
The number 413 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 413

Advancing to step 2:
If we divide 85 by 413, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 413

Advancing to step 3:
413 can be fit into 855 2 times, resulting in a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 826 from 855 to get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 413

Advancing to step 4:
The number 413 fits into 298 0 times, leaving a remainder of 298.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 298 after subtracting 0 from 298.
Take the next digit (1) from the dividend and append it to 298, then repeat: 2981 / 413

Advancing to step 5:
2981 divided by 413 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 207.0
If we take 2891 away from 2981, we end up with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 413

On to step 6:
413 goes into 904 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 2072.0
Deduct 826 from 904 and we're left with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 413

On to step 7:
The number 413 fits into 782 1 times, leaving a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 20721.0
If we take 413 away from 782, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 8:
When dividing 3690 by 413, we get 8 with a remainder of 386.
The next digit of our result is 8. 
Result so far: 20721.8
Subtracting 3304 from 3690 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 9:
3860 divided by 413 is 9 with a remainder of 143.
Put 9 as the next digit of the answer. 
Result so far: 20721.89
If we take 3717 away from 3860, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 10:
The number 413 fits into 1430 3 times, leaving a remainder of 191.
The next digit of our result is 3. 
Result so far: 20721.893
Deduct 1239 from 1430 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 11:
1910 divided by 413 is 4 with a remainder of 258.
Put 4 as the next digit of the answer. 
Result so far: 20721.8934
Subtracting 1652 from 1910 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 12:
413 goes into 2580 6 times with a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 20721.89346
The remainder is 102 after subtracting 2478 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 13:
The number 413 fits into 1020 2 times, leaving a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 20721.893462
Deduct 826 from 1020 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 14:
When dividing 1940 by 413, we get 4 with a remainder of 288.
The next digit of our result is 4. 
Result so far: 20721.8934624
Subtracting 1652 from 1940 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
When dividing 2880 by 413, we get 6 with a remainder of 402.
Write down 6 as next digit of the result. 
Result so far: 20721.89346246
Deduct 2478 from 2880 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

After the division, we end up with 20721.89346246 and a remainder of 4.02e-07.
