We're dividing 990642 by 23 
We want to divide 990642 by 23.

Let's proceed to step 1:
23 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 23

Step 2:
If we divide 99 by 23, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 7 after subtracting 92 from 99.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 23

On to step 3:
70 divided by 23 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 69 from 70 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 23

Moving on to step 4:
23 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
If we subtract 0 from 16, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 23

On to step 5:
23 can be fit into 164 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4307.0
Deduct 161 from 164 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 23

Let's proceed to step 6:
When dividing 32 by 23, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 43071.0
The remainder is 9 after subtracting 23 from 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 43071.3
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.

Moving on to step 8:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 43071.39
Subtract 207 from 210 to 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.

Step 9:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 43071.391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
When dividing 70 by 23, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43071.3913
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.

Advancing to step 11:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 43071.3913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 43071.391304
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.

On to step 13:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 43071.3913043
Subtract 69 from 80 to get 11.
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 14:
The number 23 fits into 110 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 43071.39130434
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.

In conclusion, the division gives 43071.39130434 with a balance of 1.8e-08.
