78780696 ÷ 259 
We're looking to find how many times 259 goes into 78780696.

Going ahead to step 1:
7 divided by 259 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 259

Advancing to step 2:
259 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 259

Let's proceed to step 3:
787 divided by 259 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 777 away from 787, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 259

Step 4:
When dividing 108 by 259, we get 0 with a remainder of 108.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 108, we get 108.
Append the next digit (0) from the dividend to 108 and continue with: 1080 / 259

Moving on to step 5:
When dividing 1080 by 259, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
If we take 1036 away from 1080, we end up with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 259

On to step 6:
The number 259 fits into 446 1 times, leaving a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 3041.0
The remainder is 187 after subtracting 259 from 446.
Append the next digit (9) from the dividend to 187 and continue with: 1879 / 259

Step 7:
The number 259 fits into 1879 7 times, leaving a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 30417.0
If we subtract 1813 from 1879, we get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 259

Moving on to step 8:
If we divide 666 by 259, we get 2 and a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 304172.0
Subtract 518 from 666 to 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.

Let's proceed to step 9:
259 goes into 1480 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 304172.5
The remainder is 185 after subtracting 1295 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 10:
1850 divided by 259 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 304172.57
The remainder is 37 after subtracting 1813 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
259 can be fit into 370 1 times, resulting in a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 304172.571
Subtract 259 from 370 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 12:
259 can be fit into 1110 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 304172.5714
Subtracting 1036 from 1110 leaves us 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 13:
The number 259 fits into 740 2 times, leaving a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 304172.57142
Deduct 518 from 740 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 14:
When dividing 2220 by 259, we get 8 with a remainder of 148.
Record the quotient 8 as the next digit in the result. 
Result so far: 304172.571428
Deduct 2072 from 2220 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
1480 divided by 259 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 304172.5714285
If we take 1295 away from 1480, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 16:
1850 divided by 259 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 304172.57142857
Subtract 1813 from 1850 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 304172.57142857, with a leftover of 3.7e-08.
