Let's divide 76278689 by 225
Our goal is to divide 76278689 by 225.

Moving on to step 1:
When dividing 7 by 225, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 225

Moving on to step 2:
When dividing 76 by 225, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 225

Advancing to step 3:
225 goes into 762 3 times with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 675 from 762 to get 87.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 225

Step 4:
When dividing 877 by 225, we get 3 with a remainder of 202.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 675 from 877, we get 202.
Take the next digit (8) from the dividend and append it to 202, then repeat: 2028 / 225

Advancing to step 5:
When dividing 2028 by 225, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 339.0
Subtract 2025 from 2028 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 225

On to step 6:
36 divided by 225 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 3390.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 225

On to step 7:
When dividing 368 by 225, we get 1 with a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 33901.0
Subtract 225 from 368 to get 143.
Grab the next digit (9) from the dividend, add it to 143, then carry on: 1439 / 225

Going ahead to step 8:
225 can be fit into 1439 6 times, resulting in a remainder of 89.
Put 6 as the next digit of the answer. 
Result so far: 339016.0
The remainder is 89 after subtracting 1350 from 1439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
890 divided by 225 is 3 with a remainder of 215.
Use 3 as the next digit of our solution. 
Result so far: 339016.3
Subtract 675 from 890 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 10:
225 can be fit into 2150 9 times, resulting in a remainder of 125.
Put 9 as the next digit of the answer. 
Result so far: 339016.39
Deduct 2025 from 2150 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
225 goes into 1250 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 339016.395
The remainder is 125 after subtracting 1125 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
225 can be fit into 1250 5 times, resulting in a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 339016.3955
If we take 1125 away from 1250, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 339016.3955 with a remaining 0.00125.
