We're dividing 11925890 by 23 
Let's see how many times 23 fits into 11925890.

On to step 1:
23 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 23

Going ahead to step 2:
23 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 23

Going ahead to step 3:
If we divide 119 by 23, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 115 from 119 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 23

Moving on to step 4:
The number 23 fits into 42 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 23 from 42 and we're left with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 23

Moving on to step 5:
When dividing 195 by 23, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 518.0
Subtracting 184 from 195 leaves us with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 23

Going ahead to step 6:
If we divide 118 by 23, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5185.0
If we take 115 away from 118, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 23

Let's proceed to step 7:
If we divide 39 by 23, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 51851.0
The remainder is 16 after subtracting 23 from 39.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 23

Moving on to step 8:
160 divided by 23 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 518516.0
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 518516.9
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
When dividing 130 by 23, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 518516.95
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 518516.956
If we take 138 away from 150, 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.

Advancing to step 12:
When dividing 120 by 23, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 518516.9565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
23 goes into 50 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 518516.95652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 518516.956521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 15:
If we divide 170 by 23, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 518516.9565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 16:
23 can be fit into 90 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 518516.95652173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 518516.95652173 and a remainder of 2.1e-08.
