We're dividing 402298 by 23 
We want to divide 402298 by 23.

Step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 23

Let's proceed to step 2:
23 goes into 40 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 23 away from 40, we end up with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 23

Moving on to step 3:
23 can be fit into 172 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 161 from 172 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 23

Advancing to step 4:
23 goes into 112 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 174.0
The remainder is 20 after subtracting 92 from 112.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 23

Going ahead to step 5:
209 divided by 23 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1749.0
If we take 207 away from 209, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 23

Moving on to step 6:
When dividing 28 by 23, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 17491.0
The remainder is 5 after subtracting 23 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 17491.2
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
23 goes into 40 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 17491.21
Subtracting 23 from 40 leaves us 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.

Advancing to step 9:
170 divided by 23 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17491.217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
90 divided by 23 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 17491.2173
Deduct 69 from 90 and we're left 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.

Let's proceed to step 11:
When dividing 210 by 23, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 17491.21739
Subtracting 207 from 210 leaves us with 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 12:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 17491.217391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 23, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 17491.2173913
If we subtract 69 from 70, we get 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 14:
If we divide 10 by 23, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 17491.2173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 17491.2173913, and the remainder is 1e-08.
