Let's divide 78754099 by 258
Let's see how many times 258 fits into 78754099.

Going ahead to step 1:
When dividing 7 by 258, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 258

Moving on to step 2:
When dividing 78 by 258, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 258

Moving on to step 3:
If we divide 787 by 258, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 774 from 787 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 258

Let's proceed to step 4:
258 can be fit into 135 0 times, resulting in a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 135 leaves us with 135.
Grab the next digit (4) from the dividend, add it to 135, then carry on: 1354 / 258

Let's proceed to step 5:
If we divide 1354 by 258, we get 5 and a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
If we subtract 1290 from 1354, we get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 258

Moving on to step 6:
When dividing 640 by 258, we get 2 with a remainder of 124.
The next digit of our result is 2. 
Result so far: 3052.0
Subtracting 516 from 640 leaves us with 124.
Grab the next digit (9) from the dividend, add it to 124, then carry on: 1249 / 258

Going ahead to step 7:
The number 258 fits into 1249 4 times, leaving a remainder of 217.
Record the quotient 4 as the next digit in the result. 
Result so far: 30524.0
Subtract 1032 from 1249 to get 217.
Take the next digit (9) from the dividend and append it to 217, then repeat: 2179 / 258

On to step 8:
258 goes into 2179 8 times with a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 305248.0
The remainder is 115 after subtracting 2064 from 2179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 9:
1150 divided by 258 is 4 with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 305248.4
The remainder is 118 after subtracting 1032 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
258 goes into 1180 4 times with a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 305248.44
If we subtract 1032 from 1180, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

In conclusion, the division gives 305248.44 with a balance of 0.148.
