We look at the division of 312676 by 84 
Our goal is to divide 312676 by 84.

Step 1:
84 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 84

Advancing to step 2:
The number 84 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 84

Step 3:
84 can be fit into 312 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 252 from 312 to get 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 84

Going ahead to step 4:
84 can be fit into 606 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 588 from 606 to get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 84

Going ahead to step 5:
187 divided by 84 is 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Deduct 168 from 187 and we're left with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 84

Step 6:
84 can be fit into 196 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3722.0
Subtracting 168 from 196 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
The number 84 fits into 280 3 times, leaving a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 3722.3
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
84 can be fit into 280 3 times, resulting in a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 3722.33
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 3722.33 with a remaining 0.028.
