870778 ÷ 23 
Our goal is to divide 870778 by 23.

Let's proceed to step 1:
8 divided by 23 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 23

On to step 2:
When dividing 87 by 23, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 69 from 87, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 23

Let's proceed to step 3:
When dividing 180 by 23, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 19 after subtracting 161 from 180.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 23

Advancing to step 4:
If we divide 197 by 23, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 378.0
Subtracting 184 from 197 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 23

Moving on to step 5:
When dividing 137 by 23, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 3785.0
Deduct 115 from 137 and we're left with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 23

Let's proceed to step 6:
23 can be fit into 228 9 times, resulting in a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 37859.0
The remainder is 21 after subtracting 207 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 37859.9
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 37859.91
Subtracting 23 from 30 leaves us 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.

Advancing to step 9:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 37859.913
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.

Let's proceed to step 10:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 37859.913
Deduct 0 from 10 and we're left 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.

Let's proceed to step 11:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 37859.91304
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.

Step 12:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 37859.913043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
23 goes into 110 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 37859.9130434
The remainder is 18 after subtracting 92 from 110.
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 14:
180 divided by 23 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 37859.91304347
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.

After the division, we end up with 37859.91304347 and a remainder of 1.9e-08.
