We look at the division of 285173 by 78 
We're looking to find how many times 78 goes into 285173.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 78

Step 2:
28 divided by 78 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 78

Moving on to step 3:
When dividing 285 by 78, we get 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 234 from 285 leaves us with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 78

Let's proceed to step 4:
511 divided by 78 is 6 with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 468 from 511, we get 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 78

Let's proceed to step 5:
The number 78 fits into 437 5 times, leaving a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 365.0
The remainder is 47 after subtracting 390 from 437.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 78

Advancing to step 6:
If we divide 473 by 78, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 3656.0
If we take 468 away from 473, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 78, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 3656.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
If we divide 500 by 78, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 3656.06
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 78, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3656.064
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 3656.0641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 78 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3656.0641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 3656.064102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3656.0641025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
When dividing 500 by 78, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 3656.06410256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 3656.06410256, and the remainder is 3.2e-08.
