225224 ÷ 78 
Our goal is to divide 225224 by 78.

Advancing to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 78

Let's proceed to step 2:
22 divided by 78 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 78

Moving on to step 3:
The number 78 fits into 225 2 times, leaving a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 156 from 225 to get 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 78

Moving on to step 4:
If we divide 692 by 78, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 624 from 692 leaves us with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 78

Advancing to step 5:
The number 78 fits into 682 8 times, leaving a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 288.0
The remainder is 58 after subtracting 624 from 682.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 78

Step 6:
78 can be fit into 584 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 2887.0
The remainder is 38 after subtracting 546 from 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 2887.4
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
78 goes into 680 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 2887.48
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
The number 78 fits into 560 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2887.487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 2887.4871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
620 divided by 78 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 2887.48717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
740 divided by 78 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 2887.487179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 2887.4871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
78 goes into 680 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 2887.48717948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 2887.48717948 with a remaining 5.6e-08.
