421158 divided by 82 
Let's see how many times 82 fits into 421158.

Moving on to step 1:
4 divided by 82 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 82

Moving on to step 2:
When dividing 42 by 82, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 82

Going ahead to step 3:
When dividing 421 by 82, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 410 away from 421, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 82

Going ahead to step 4:
When dividing 111 by 82, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 82 from 111 to get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 82

Step 5:
The number 82 fits into 295 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 513.0
Deduct 246 from 295 and we're left with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 82

Let's proceed to step 6:
82 goes into 498 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 5136.0
The remainder is 6 after subtracting 492 from 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 82 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 5136.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 82 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 5136.07
Subtract 574 from 600 to get 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 9:
The number 82 fits into 260 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 5136.073
Deduct 246 from 260 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
82 can be fit into 140 1 times, resulting in a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 5136.0731
Subtract 82 from 140 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
The number 82 fits into 580 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 5136.07317
The remainder is 6 after subtracting 574 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
82 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5136.07317
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
82 can be fit into 600 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 5136.0731707
Subtracting 574 from 600 leaves us 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.

Advancing to step 14:
82 can be fit into 260 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 5136.07317073
If we subtract 246 from 260, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 5136.07317073 with a remainder of 1.4e-08.
