We're dividing 305178 by 84 
We want to figure out the number of times 305178 can be divided by 84.

Advancing to step 1:
3 divided by 84 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 84

On to step 2:
The number 84 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 84

Going ahead to step 3:
When dividing 305 by 84, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 252 from 305 leaves us with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 84

Let's proceed to step 4:
When dividing 531 by 84, we get 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 504 from 531, we get 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 84

Advancing to step 5:
If we divide 277 by 84, we get 3 and a remainder of 25.
The next digit of our result is 3. 
Result so far: 363.0
Deduct 252 from 277 and we're left with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 84

Advancing to step 6:
84 can be fit into 258 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3633.0
If we subtract 252 from 258, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
84 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3633.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
84 goes into 600 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3633.07
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 84, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 3633.071
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
If we divide 360 by 84, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3633.0714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 84, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 3633.07142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
If we divide 720 by 84, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 3633.071428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
84 goes into 480 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 3633.0714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 3633.07142857
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 3633.07142857 and a remainder of 1.2e-08.
