859402 divided by 23 
Our goal is to divide 859402 by 23.

Let's proceed to step 1:
8 divided by 23 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 23

Advancing to step 2:
If we divide 85 by 23, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 69 away from 85, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 23

Step 3:
23 can be fit into 169 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 161 from 169 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 23

Step 4:
23 goes into 84 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
If we subtract 69 from 84, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 23

Step 5:
When dividing 150 by 23, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3736.0
Deduct 138 from 150 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 23

Moving on to step 6:
23 goes into 122 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 37365.0
If we take 115 away from 122, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 37365.3
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 23, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 37365.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 23 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 37365.304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
23 goes into 80 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 37365.3043
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 23, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 37365.30434
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 37365.304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
23 can be fit into 190 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 37365.3043478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
60 divided by 23 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 37365.30434782
Deduct 46 from 60 and we're left 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.

The final outcome is 37365.30434782, with a leftover of 1.4e-08.
