Let's divide 859394 by 78
We want to figure out the number of times 859394 can be divided by 78.

Step 1:
78 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 78

Step 2:
When dividing 85 by 78, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 7 after subtracting 78 from 85.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 78

Going ahead to step 3:
78 can be fit into 79 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 78 from 79 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 78

Moving on to step 4:
78 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtract 0 from 13 to get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 78

Moving on to step 5:
139 divided by 78 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
Subtracting 78 from 139 leaves us with 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 78

Moving on to step 6:
If we divide 614 by 78, we get 7 and a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 11017.0
The remainder is 68 after subtracting 546 from 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 11017.8
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.

Step 8:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11017.87
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
78 goes into 140 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 11017.871
Deduct 78 from 140 and we're left 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.

Moving on to step 10:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 11017.8717
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.

Going ahead to step 11:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 11017.87179
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.

Step 12:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 11017.871794
Subtracting 312 from 380 leaves us 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.

Step 13:
If we divide 680 by 78, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 11017.8717948
Subtract 624 from 680 to 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 14:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 11017.87179487
Subtract 546 from 560 to 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.

After the division, we end up with 11017.87179487 and a remainder of 1.4e-08.
