405 divided by 83 
Let's see how many times 83 fits into 405.

On to step 1:
When dividing 4 by 83, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 83

Advancing to step 2:
40 divided by 83 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 83

Step 3:
When dividing 405 by 83, we get 4 with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 332 away from 405, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 4:
730 divided by 83 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 4.8
Deduct 664 from 730 and we're left with 66.
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 5:
When dividing 660 by 83, we get 7 with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 4.87
Subtracting 581 from 660 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 6:
83 can be fit into 790 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 4.879
If we take 747 away from 790, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
If we divide 430 by 83, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4.8795
Subtract 415 from 430 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 83, we get 1 and a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 4.87951
If we take 83 away from 150, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
670 divided by 83 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 4.879518
Subtract 664 from 670 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 83 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4.879518
Deduct 0 from 60 and we're left 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 11:
If we divide 600 by 83, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 4.87951807
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 4.87951807, and the remainder is 1.9e-08.
