859864 divided by 78 
We're looking to find how many times 78 goes into 859864.

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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 78

On to step 2:
85 divided by 78 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 78 from 85 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 78

Let's proceed to step 3:
78 goes into 79 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 78 from 79 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 78

Let's proceed to step 4:
78 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 78

Let's proceed to step 5:
186 divided by 78 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 1102.0
If we take 156 away from 186, we end up with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 78

On to step 6:
The number 78 fits into 304 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 11023.0
If we take 234 away from 304, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
If we divide 700 by 78, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 11023.8
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 11023.89
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
78 goes into 580 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 11023.897
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11023.8974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 11023.89743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
78 goes into 460 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 11023.897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
78 goes into 700 8 times with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 11023.8974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
78 goes into 760 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 11023.89743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 11023.89743589, with a leftover of 5.8e-08.
