We divide 83080843 by 421
Our goal is to divide 83080843 by 421.

Let's proceed to step 1:
When dividing 8 by 421, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 421

Advancing to step 2:
The number 421 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 421

Advancing to step 3:
The number 421 fits into 830 1 times, leaving a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 421 away from 830, we end up with 409.
Fetch the next digit (8) from the dividend, attach it to 409 and continue: 4098 / 421

Step 4:
421 can be fit into 4098 9 times, resulting in a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 3789 away from 4098, we end up with 309.
Include the next digit (0) from the dividend after 309, then repeat: 3090 / 421

Moving on to step 5:
The number 421 fits into 3090 7 times, leaving a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 197.0
Subtracting 2947 from 3090 leaves us with 143.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 421

Going ahead to step 6:
421 goes into 1438 3 times with a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 1973.0
If we take 1263 away from 1438, we end up with 175.
Append the next digit (4) from the dividend to 175 and continue with: 1754 / 421

Going ahead to step 7:
421 can be fit into 1754 4 times, resulting in a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 19734.0
Subtracting 1684 from 1754 leaves us with 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 421

Step 8:
If we divide 703 by 421, we get 1 and a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 197341.0
Subtract 421 from 703 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
2820 divided by 421 is 6 with a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 197341.6
Subtracting 2526 from 2820 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
2940 divided by 421 is 6 with a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 197341.66
Subtract 2526 from 2940 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 197341.66 with a remainder of 0.414.
