We look at the division of 978158 by 78 
We're looking to find how many times 78 goes into 978158.

Going ahead to step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 78

On to step 2:
78 goes into 97 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the 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

Moving on to step 3:
If we divide 198 by 78, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 156 from 198, we get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 78

Step 4:
78 can be fit into 421 5 times, resulting in a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtracting 390 from 421 leaves us with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 78

Moving on to step 5:
If we divide 315 by 78, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
If we subtract 312 from 315, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Advancing to step 6:
The number 78 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 12540.0
Subtract 0 from 38 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 12540.4
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
680 divided by 78 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 12540.48
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
When dividing 560 by 78, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 12540.487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 12540.4871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 12540.48717
Deduct 546 from 620 and we're left 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.

Going ahead to step 12:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 12540.487179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 12540.4871794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
If we divide 680 by 78, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 12540.48717948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 12540.48717948, and the remainder is 5.6e-08.
