Let's divide 406374 by 84
We want to divide 406374 by 84.

Step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 84

On to step 2:
40 divided by 84 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 84

Going ahead to step 3:
406 divided by 84 is 4 with a remainder of 70.
The next digit of our result is 4. 
Result so far: 4.0
If we take 336 away from 406, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 84

Advancing to step 4:
If we divide 703 by 84, we get 8 and a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 672 from 703, we get 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 84

Moving on to step 5:
When dividing 317 by 84, we get 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 483.0
Subtracting 252 from 317 leaves us with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 84

On to step 6:
The number 84 fits into 654 7 times, leaving a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 4837.0
Deduct 588 from 654 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.

Moving on to step 7:
84 goes into 660 7 times with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 4837.7
The remainder is 72 after subtracting 588 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
720 divided by 84 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4837.78
Deduct 672 from 720 and we're left 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.

Moving on to step 9:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 4837.785
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.

Moving on to step 10:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 4837.7857
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 4837.78571
If we take 84 away from 120, we end up 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.

On to step 12:
If we divide 360 by 84, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4837.785714
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.

Going ahead to step 13:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 4837.7857142
Subtracting 168 from 240 leaves us 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 14:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4837.78571428
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 4837.78571428 and a remainder of 4.8e-08.
