Let's divide 343335 by 84
Our goal is to divide 343335 by 84.

On to step 1:
3 divided by 84 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 84

Step 2:
84 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 84

On to step 3:
84 goes into 343 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 336 from 343 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 84

On to step 4:
The number 84 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 84

Step 5:
The number 84 fits into 733 8 times, leaving a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 408.0
If we subtract 672 from 733, we get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 84

Going ahead to step 6:
615 divided by 84 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 4087.0
Subtract 588 from 615 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
When dividing 270 by 84, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 4087.3
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
The number 84 fits into 180 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 4087.32
Subtracting 168 from 180 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.

Going ahead to step 9:
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: 4087.321
If we subtract 84 from 120, we get 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 10:
360 divided by 84 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4087.3214
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 11:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 4087.32142
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.

Moving on to step 12:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 4087.321428
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.

On to step 13:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4087.3214285
If we subtract 420 from 480, we 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 14:
When dividing 600 by 84, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 4087.32142857
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.

In conclusion, the division gives 4087.32142857 with a balance of 1.2e-08.
