We look at the division of 400284 by 84 
Our goal is to divide 400284 by 84.

On to step 1:
The number 84 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 84

Going ahead to step 2:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 84

Let's proceed to step 3:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 336 from 400 to get 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 84

Advancing to step 4:
When dividing 642 by 84, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 588 from 642 to get 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 84

On to step 5:
If we divide 548 by 84, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 476.0
If we subtract 504 from 548, we get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 84

Step 6:
444 divided by 84 is 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 4765.0
Deduct 420 from 444 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
240 divided by 84 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 4765.2
Deduct 168 from 240 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.

Step 8:
When dividing 720 by 84, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4765.28
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 4765.285
If we take 420 away from 480, 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.

Step 10:
600 divided by 84 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 4765.2857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 4765.28571
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 84, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4765.285714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 4765.2857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4765.28571428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 4765.28571428 and a remainder of 4.8e-08.
