We look at the division of 425343 by 84 
We're looking to find how many times 84 goes into 425343.

Going ahead to step 1:
84 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 84

Step 2:
The number 84 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 84

On to step 3:
When dividing 425 by 84, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 5 after subtracting 420 from 425.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 84

Let's proceed to step 4:
53 divided by 84 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we subtract 0 from 53, we get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 84

Step 5:
If we divide 534 by 84, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 506.0
Subtract 504 from 534 to get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 84

On to step 6:
When dividing 303 by 84, we get 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 5063.0
Subtracting 252 from 303 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
510 divided by 84 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 5063.6
Subtract 504 from 510 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.

Advancing to step 8:
When dividing 60 by 84, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5063.6
Subtract 0 from 60 to get 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 9:
600 divided by 84 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 5063.607
If we take 588 away from 600, we end up 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.

Moving on to step 10:
If we divide 120 by 84, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 5063.6071
The remainder is 36 after subtracting 84 from 120.
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 11:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 5063.60714
If we subtract 336 from 360, we get 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 12:
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: 5063.607142
If we subtract 168 from 240, we get 72.
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 13:
84 goes into 720 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5063.6071428
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.

Step 14:
If we divide 480 by 84, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 5063.60714285
Subtracting 420 from 480 leaves us 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.

The final result is 5063.60714285 with a remainder of 6e-08.
