We look at the division of 82435016 by 421 
Our goal is to divide 82435016 by 421.

Moving on to step 1:
8 divided by 421 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 421

Step 2:
421 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 421

Advancing to step 3:
The number 421 fits into 824 1 times, leaving a remainder of 403.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 421 away from 824, we end up with 403.
Include the next digit (3) from the dividend after 403, then repeat: 4033 / 421

On to step 4:
4033 divided by 421 is 9 with a remainder of 244.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3789 from 4033 to get 244.
Append the next digit (5) from the dividend to 244 and continue with: 2445 / 421

Let's proceed to step 5:
421 can be fit into 2445 5 times, resulting in a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Deduct 2105 from 2445 and we're left with 340.
Bring next digit (0) of the dividend behind the 340 and repeat the process: 3400 / 421

Advancing to step 6:
421 goes into 3400 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1958.0
If we take 3368 away from 3400, we end up with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 421

Step 7:
If we divide 321 by 421, we get 0 and a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 19580.0
If we subtract 0 from 321, we get 321.
Bring next digit (6) of the dividend behind the 321 and repeat the process: 3216 / 421

Going ahead to step 8:
421 can be fit into 3216 7 times, resulting in a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 195807.0
If we take 2947 away from 3216, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 9:
If we divide 2690 by 421, we get 6 and a remainder of 164.
The next digit of our result is 6. 
Result so far: 195807.6
If we subtract 2526 from 2690, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
421 can be fit into 1640 3 times, resulting in a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 195807.63
Deduct 1263 from 1640 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 11:
421 goes into 3770 8 times with a remainder of 402.
Use 8 as the next digit of our solution. 
Result so far: 195807.638
If we take 3368 away from 3770, we end up 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.

Advancing to step 12:
4020 divided by 421 is 9 with a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 195807.6389
Subtracting 3789 from 4020 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 13:
421 goes into 2310 5 times with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 195807.63895
Subtract 2105 from 2310 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 14:
The number 421 fits into 2050 4 times, leaving a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 195807.638954
Subtract 1684 from 2050 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 15:
The number 421 fits into 3660 8 times, leaving a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 195807.6389548
Subtracting 3368 from 3660 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 16:
When dividing 2920 by 421, we get 6 with a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 195807.63895486
Deduct 2526 from 2920 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

The quotient of the division is 195807.63895486, and the remainder is 3.94e-07.
