Let's divide 859080 by 78
We're looking to find how many times 78 goes into 859080.

Step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 78

On to step 2:
78 can be fit into 85 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 78 from 85, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 78

Moving on to step 3:
78 goes into 79 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 78 from 79 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 78

Advancing to step 4:
When dividing 10 by 78, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 10, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 78

Moving on to step 5:
78 can be fit into 108 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 1101.0
Deduct 78 from 108 and we're left with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 78

Let's proceed to step 6:
300 divided by 78 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 11013.0
Subtract 234 from 300 to 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.

Advancing to step 7:
78 goes into 660 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 11013.8
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 78, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 11013.84
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
When dividing 480 by 78, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11013.846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 78, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 11013.8461
If we take 78 away from 120, we end up 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.

On to step 11:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11013.84615
Subtracting 390 from 420 leaves us 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.

Advancing to step 12:
78 goes into 300 3 times with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 11013.846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
When dividing 660 by 78, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 11013.8461538
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.

Let's proceed to step 14:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 11013.84615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 11013.84615384 with a remaining 4.8e-08.
