We divide 313215 by 84
We want to divide 313215 by 84.

On to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 84

Let's proceed to step 2:
84 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 84

Going ahead to step 3:
84 goes into 313 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 252 from 313 leaves us with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 84

Moving on to step 4:
If we divide 612 by 84, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 588 from 612, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 84

Step 5:
When dividing 241 by 84, we get 2 with a remainder of 73.
The next digit of our result is 2. 
Result so far: 372.0
If we take 168 away from 241, we end up with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 84

Step 6:
The number 84 fits into 735 8 times, leaving a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 3728.0
If we subtract 672 from 735, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
84 can be fit into 630 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 3728.7
Deduct 588 from 630 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
If we divide 420 by 84, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3728.75
If we take 420 away from 420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
84 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3728.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 84, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3728.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3728.75 with a remaining 0.0.
