Let's divide 12623937 by 45
Our goal is to divide 12623937 by 45.

Going ahead to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 45

Going ahead to step 2:
45 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 45

Going ahead to step 3:
When dividing 126 by 45, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 90 away from 126, we end up with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 45

Let's proceed to step 4:
When dividing 362 by 45, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 360 from 362 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 45

Step 5:
The number 45 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 280.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Let's proceed to step 6:
239 divided by 45 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 2805.0
If we take 225 away from 239, we end up with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 45

Step 7:
The number 45 fits into 143 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 28053.0
Subtracting 135 from 143 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 45

Let's proceed to step 8:
45 can be fit into 87 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 280531.0
If we subtract 45 from 87, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
420 divided by 45 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 280531.9
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 45, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 280531.93
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 280531.933
If we take 135 away from 150, we end up 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.

In conclusion, the division gives 280531.933 with a balance of 0.0015.
