We look at the division of 343375 by 84 
Our goal is to divide 343375 by 84.

Step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 84

Moving on to step 2:
84 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 84

Moving on to step 3:
84 can be fit into 343 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 336 from 343 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 84

Let's proceed to step 4:
84 goes into 73 0 times with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 84

Going ahead to step 5:
The number 84 fits into 737 8 times, leaving a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
Subtracting 672 from 737 leaves us with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 84

Moving on to step 6:
84 goes into 655 7 times with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 4087.0
The remainder is 67 after subtracting 588 from 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
84 goes into 670 7 times with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 4087.7
Deduct 588 from 670 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
84 goes into 820 9 times with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 4087.79
If we subtract 756 from 820, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 84 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 4087.797
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 4087.7976
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 84, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 4087.79761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
If we divide 760 by 84, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 4087.797619
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 84, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4087.797619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 84, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4087.79761904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 4087.79761904 with a remaining 6.4e-08.
