We divide 82405945 by 421
We want to divide 82405945 by 421.

On to step 1:
8 divided by 421 is 0 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.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 421

Let's proceed to step 2:
The number 421 fits into 82 0 times, leaving a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 421

Let's proceed to step 3:
When dividing 824 by 421, we get 1 with a remainder of 403.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 421 from 824 leaves us with 403.
Include the next digit (0) from the dividend after 403, then repeat: 4030 / 421

Step 4:
The number 421 fits into 4030 9 times, leaving a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 3789 from 4030 and we're left with 241.
Take the next digit (5) from the dividend and append it to 241, then repeat: 2415 / 421

Let's proceed to step 5:
When dividing 2415 by 421, we get 5 with a remainder of 310.
The next digit of our result is 5. 
Result so far: 195.0
If we subtract 2105 from 2415, we get 310.
Fetch the next digit (9) from the dividend, attach it to 310 and continue: 3109 / 421

Let's proceed to step 6:
421 can be fit into 3109 7 times, resulting in a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 1957.0
Deduct 2947 from 3109 and we're left with 162.
Include the next digit (4) from the dividend after 162, then repeat: 1624 / 421

On to step 7:
421 can be fit into 1624 3 times, resulting in a remainder of 361.
Record the quotient 3 as the next digit in the result. 
Result so far: 19573.0
Deduct 1263 from 1624 and we're left with 361.
Grab the next digit (5) from the dividend, add it to 361, then carry on: 3615 / 421

Moving on to step 8:
3615 divided by 421 is 8 with a remainder of 247.
The next digit of our result is 8. 
Result so far: 195738.0
If we take 3368 away from 3615, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 9:
When dividing 2470 by 421, we get 5 with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 195738.5
Subtracting 2105 from 2470 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 10:
If we divide 3650 by 421, we get 8 and a remainder of 282.
The next digit of our result is 8. 
Result so far: 195738.58
Deduct 3368 from 3650 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 11:
When dividing 2820 by 421, we get 6 with a remainder of 294.
Record the quotient 6 as the next digit in the result. 
Result so far: 195738.586
If we take 2526 away from 2820, we end up 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.

Going ahead to step 12:
When dividing 2940 by 421, we get 6 with a remainder of 414.
Put 6 as the next digit of the answer. 
Result so far: 195738.5866
The remainder is 414 after subtracting 2526 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The quotient of the division is 195738.5866, and the remainder is 0.00414.
