We're dividing 155421 by 82 
We want to figure out the number of times 155421 can be divided by 82.

Let's proceed to step 1:
If we divide 1 by 82, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 82

On to step 2:
If we divide 15 by 82, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 82

Step 3:
82 goes into 155 1 times with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 82 from 155 leaves us with 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 82

Advancing to step 4:
If we divide 734 by 82, we get 8 and a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 78 after subtracting 656 from 734.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 82

Let's proceed to step 5:
82 can be fit into 782 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 189.0
If we take 738 away from 782, we end up with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 82

Step 6:
441 divided by 82 is 5 with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 1895.0
If we subtract 410 from 441, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
The number 82 fits into 310 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 1895.3
If we subtract 246 from 310, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
640 divided by 82 is 7 with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 1895.37
The remainder is 66 after subtracting 574 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
The number 82 fits into 660 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1895.378
Subtracting 656 from 660 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
82 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1895.378
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 82 fits into 400 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 1895.37804
Deduct 328 from 400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
The number 82 fits into 720 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 1895.378048
Subtracting 656 from 720 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
If we divide 640 by 82, we get 7 and a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 1895.3780487
Subtract 574 from 640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
The number 82 fits into 660 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1895.37804878
If we take 656 away from 660, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 1895.37804878 with a balance of 4e-09.
