We look at the division of 859170 by 24 
We want to figure out the number of times 859170 can be divided by 24.

On to step 1:
24 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 24

Let's proceed to step 2:
When dividing 85 by 24, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 72 from 85 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 24

Let's proceed to step 3:
139 divided by 24 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 19 after subtracting 120 from 139.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 24

Advancing to step 4:
24 goes into 191 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 357.0
If we take 168 away from 191, we end up with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 24

Advancing to step 5:
24 can be fit into 237 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 3579.0
If we take 216 away from 237, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 24

Let's proceed to step 6:
24 can be fit into 210 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 35798.0
If we subtract 192 from 210, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 24, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 35798.7
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
24 can be fit into 120 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 35798.75
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35798.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
24 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35798.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 35798.75 with a remaining 0.0.
