We're dividing 878120 by 78 
Our goal is to divide 878120 by 78.

Going ahead to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 78

Let's proceed to step 2:
87 divided by 78 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 87, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 78

Going ahead to step 3:
If we divide 98 by 78, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 78 from 98 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 78

Step 4:
When dividing 201 by 78, we get 2 with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Deduct 156 from 201 and we're left with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 78

Advancing to step 5:
78 goes into 452 5 times with a remainder of 62.
The next digit of our result is 5. 
Result so far: 1125.0
Subtract 390 from 452 to get 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 78

Step 6:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 11257.0
If we take 546 away from 620, we end up 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.

Moving on to step 7:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 11257.9
Subtracting 702 from 740 leaves us with 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 8:
380 divided by 78 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 11257.94
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
78 goes into 680 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 11257.948
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.

On to step 10:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11257.9487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
78 goes into 140 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 11257.94871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
620 divided by 78 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 11257.948717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 11257.9487179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
78 can be fit into 380 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 11257.94871794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 11257.94871794, and the remainder is 6.8e-08.
