309372 divided by 84 
We want to divide 309372 by 84.

Advancing to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 84

Going ahead to step 2:
The number 84 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 84

Moving on to step 3:
The number 84 fits into 309 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 252 from 309, we get 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 84

On to step 4:
If we divide 573 by 84, we get 6 and a remainder of 69.
The next digit of our result is 6. 
Result so far: 36.0
If we take 504 away from 573, we end up with 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 84

On to step 5:
84 goes into 697 8 times with a remainder of 25.
The next digit of our result is 8. 
Result so far: 368.0
If we take 672 away from 697, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 84

Moving on to step 6:
84 goes into 252 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3683.0
If we subtract 252 from 252, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
84 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3683.0
Deduct 0 from 0 and we're left 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.

Step 8:
84 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3683.0
If we take 0 away from 0, 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.

The final result is 3683.0 with a remainder of 0.0.
