We're dividing 82080857 by 421 
Our goal is to divide 82080857 by 421.

Moving on to step 1:
8 divided by 421 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 421

Let's proceed to step 2:
421 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 421

Let's proceed to step 3:
820 divided by 421 is 1 with a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 399 after subtracting 421 from 820.
Bring next digit (8) of the dividend behind the 399 and repeat the process: 3998 / 421

On to step 4:
421 goes into 3998 9 times with a remainder of 209.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 3789 from 3998 and we're left with 209.
Bring next digit (0) of the dividend behind the 209 and repeat the process: 2090 / 421

Advancing to step 5:
If we divide 2090 by 421, we get 4 and a remainder of 406.
The next digit of our result is 4. 
Result so far: 194.0
The remainder is 406 after subtracting 1684 from 2090.
Grab the next digit (8) from the dividend, add it to 406, then carry on: 4068 / 421

On to step 6:
When dividing 4068 by 421, we get 9 with a remainder of 279.
The next digit of our result is 9. 
Result so far: 1949.0
If we take 3789 away from 4068, we end up with 279.
Bring next digit (5) of the dividend behind the 279 and repeat the process: 2795 / 421

Let's proceed to step 7:
If we divide 2795 by 421, we get 6 and a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 19496.0
Deduct 2526 from 2795 and we're left with 269.
Take the next digit (7) from the dividend and append it to 269, then repeat: 2697 / 421

Step 8:
2697 divided by 421 is 6 with a remainder of 171.
The next digit of our result is 6. 
Result so far: 194966.0
If we take 2526 away from 2697, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
If we divide 1710 by 421, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 194966.4
If we take 1684 away from 1710, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
260 divided by 421 is 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 194966.4
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
421 can be fit into 2600 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 194966.406
If we take 2526 away from 2600, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
If we divide 740 by 421, we get 1 and a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 194966.4061
Deduct 421 from 740 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 13:
If we divide 3190 by 421, we get 7 and a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 194966.40617
Subtracting 2947 from 3190 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Moving on to step 14:
The number 421 fits into 2430 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 194966.406175
Deduct 2105 from 2430 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 15:
If we divide 3250 by 421, we get 7 and a remainder of 303.
Use 7 as the next digit of our solution. 
Result so far: 194966.4061757
Deduct 2947 from 3250 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 16:
3030 divided by 421 is 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 194966.40617577
Subtract 2947 from 3030 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 194966.40617577 and a remainder of 8.3e-08.
