We look at the division of 307072 by 84 
We're looking to find how many times 84 goes into 307072.

Advancing to step 1:
3 divided by 84 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 84

On to step 2:
84 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 84

Let's proceed to step 3:
If we divide 307 by 84, we get 3 and a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 252 away from 307, we end up with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 84

Moving on to step 4:
If we divide 550 by 84, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Deduct 504 from 550 and we're left with 46.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 84

Let's proceed to step 5:
The number 84 fits into 467 5 times, leaving a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 365.0
Subtracting 420 from 467 leaves us with 47.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 84

Advancing to step 6:
84 goes into 472 5 times with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 3655.0
Deduct 420 from 472 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
If we divide 520 by 84, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3655.6
If we subtract 504 from 520, we get 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 8:
160 divided by 84 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 3655.61
Subtract 84 from 160 to get 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 9:
If we divide 760 by 84, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 3655.619
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.

On to step 10:
If we divide 40 by 84, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3655.619
Deduct 0 from 40 and we're left 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.

Advancing to step 11:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 3655.61904
Deduct 336 from 400 and we're left 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.

On to step 12:
If we divide 640 by 84, we get 7 and a remainder of 52.
The next digit of our result is 7. 
Result so far: 3655.619047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
If we divide 520 by 84, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 3655.6190476
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 14:
If we divide 160 by 84, we get 1 and a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 3655.61904761
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.

After the division, we end up with 3655.61904761 and a remainder of 7.6e-08.
