284170 ÷ 78 
Let's see how many times 78 fits into 284170.

Step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 78

Advancing to step 2:
78 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 78

Going ahead to step 3:
If we divide 284 by 78, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 234 from 284 to get 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 78

Let's proceed to step 4:
When dividing 501 by 78, we get 6 with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 468 from 501 and we're left with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 78

Advancing to step 5:
When dividing 337 by 78, we get 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 364.0
The remainder is 25 after subtracting 312 from 337.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 78

Going ahead to step 6:
When dividing 250 by 78, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3643.0
If we subtract 234 from 250, 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 7:
When dividing 160 by 78, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3643.2
Deduct 156 from 160 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.

Advancing to step 8:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3643.2
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3643.205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 3643.2051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 3643.20512
Deduct 156 from 220 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.

Going ahead to step 12:
640 divided by 78 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 3643.205128
Deduct 624 from 640 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.

Going ahead to step 13:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3643.2051282
If we take 156 away from 160, we end up 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.

Let's proceed to step 14:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3643.2051282
If we take 0 away from 40, we end up 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.

Our division results in 3643.2051282 with a remaining 4e-08.
