978774 ÷ 78 
We're looking to find how many times 78 goes into 978774.

Going ahead to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 78

Advancing to step 2:
When dividing 97 by 78, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 19 after subtracting 78 from 97.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 78

Step 3:
198 divided by 78 is 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 42 after subtracting 156 from 198.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 78

Let's proceed to step 4:
If we divide 427 by 78, we get 5 and a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 390 from 427 and we're left with 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 78

Advancing to step 5:
78 goes into 377 4 times with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 1254.0
The remainder is 65 after subtracting 312 from 377.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 78

Advancing to step 6:
78 goes into 654 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 12548.0
Subtract 624 from 654 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 12548.3
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 12548.38
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
78 goes into 360 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 12548.384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12548.3846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
78 goes into 120 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 12548.38461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 12548.384615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 78, we get 3 and a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 12548.3846153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
When dividing 660 by 78, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 12548.38461538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 12548.38461538, with a leftover of 3.6e-08.
