870085 divided by 23 
We want to figure out the number of times 870085 can be divided by 23.

On to step 1:
If we divide 8 by 23, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 23

Going ahead to step 2:
23 can be fit into 87 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 69 from 87 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 23

Advancing to step 3:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 161 away from 180, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 23

Moving on to step 4:
190 divided by 23 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
Deduct 184 from 190 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 23

Going ahead to step 5:
When dividing 68 by 23, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 3782.0
If we subtract 46 from 68, we get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 23

Step 6:
23 goes into 225 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 37829.0
Subtract 207 from 225 to 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.

On to step 7:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 37829.7
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
If we divide 190 by 23, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 37829.78
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
60 divided by 23 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 37829.782
Subtract 46 from 60 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.

Going ahead to step 10:
140 divided by 23 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 37829.7826
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 37829.7826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 37829.782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 37829.7826086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
23 goes into 220 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 37829.78260869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 37829.78260869 and a remainder of 1.3e-08.
