766989 ÷ 78 
We're looking to find how many times 78 goes into 766989.

On to step 1:
78 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 78

Let's proceed to step 2:
78 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 78

On to step 3:
When dividing 766 by 78, we get 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 702 from 766 to get 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 78

Going ahead to step 4:
When dividing 649 by 78, we get 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
The remainder is 25 after subtracting 624 from 649.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 78

Step 5:
78 can be fit into 258 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 983.0
Deduct 234 from 258 and we're left with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 78

Moving on to step 6:
78 goes into 249 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 9833.0
If we subtract 234 from 249, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 78, we get 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 9833.1
Subtract 78 from 150 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
78 goes into 720 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 9833.19
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 78 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 9833.192
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 78, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 9833.1923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
78 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9833.1923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
600 divided by 78 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 9833.192307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9833.1923076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9833.19230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 9833.19230769, with a leftover of 1.8e-08.
