82042143 ÷ 408 
Our goal is to divide 82042143 by 408.

Going ahead to step 1:
When dividing 8 by 408, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 408

Moving on to step 2:
When dividing 82 by 408, we get 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 408

Moving on to step 3:
408 can be fit into 820 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 816 from 820, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 408

Going ahead to step 4:
408 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 44 leaves us with 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 408

Going ahead to step 5:
When dividing 442 by 408, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 201.0
Deduct 408 from 442 and we're left with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 408

Let's proceed to step 6:
When dividing 341 by 408, we get 0 with a remainder of 341.
Write down 0 as next digit of the result. 
Result so far: 2010.0
Subtract 0 from 341 to get 341.
Include the next digit (4) from the dividend after 341, then repeat: 3414 / 408

Let's proceed to step 7:
3414 divided by 408 is 8 with a remainder of 150.
Use 8 as the next digit of our solution. 
Result so far: 20108.0
Deduct 3264 from 3414 and we're left with 150.
Grab the next digit (3) from the dividend, add it to 150, then carry on: 1503 / 408

Going ahead to step 8:
The number 408 fits into 1503 3 times, leaving a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 201083.0
Deduct 1224 from 1503 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 9:
408 can be fit into 2790 6 times, resulting in a remainder of 342.
The number 6 becomes the next digit in our result. 
Result so far: 201083.6
If we subtract 2448 from 2790, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 10:
3420 divided by 408 is 8 with a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 201083.68
The remainder is 156 after subtracting 3264 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 11:
1560 divided by 408 is 3 with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 201083.683
The remainder is 336 after subtracting 1224 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
The number 408 fits into 3360 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 201083.6838
Subtract 3264 from 3360 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
When dividing 960 by 408, we get 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 201083.68382
If we take 816 away from 960, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 14:
If we divide 1440 by 408, we get 3 and a remainder of 216.
The next digit of our result is 3. 
Result so far: 201083.683823
Subtracting 1224 from 1440 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 15:
The number 408 fits into 2160 5 times, leaving a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 201083.6838235
Subtracting 2040 from 2160 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
The number 408 fits into 1200 2 times, leaving a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 201083.68382352
The remainder is 384 after subtracting 816 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 201083.68382352, and the remainder is 3.84e-07.
