39989459 ÷ 24 
We want to divide 39989459 by 24.

Going ahead to step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 24

Going ahead to step 2:
24 can be fit into 39 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 24 from 39, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 24

Advancing to step 3:
When dividing 159 by 24, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 144 away from 159, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 24

Going ahead to step 4:
158 divided by 24 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 166.0
Subtracting 144 from 158 leaves us with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 24

Let's proceed to step 5:
24 can be fit into 149 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 1666.0
The remainder is 5 after subtracting 144 from 149.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 24

Moving on to step 6:
If we divide 54 by 24, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 16662.0
Subtracting 48 from 54 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 24

Step 7:
65 divided by 24 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 166622.0
Deduct 48 from 65 and we're left with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 24

Step 8:
The number 24 fits into 179 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1666227.0
Subtract 168 from 179 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.

Step 9:
The number 24 fits into 110 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1666227.4
Deduct 96 from 110 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
24 goes into 140 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1666227.45
Deduct 120 from 140 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 24 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1666227.458
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 1666227.4583
If we subtract 72 from 80, we 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.

Let's proceed to step 13:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 1666227.45833
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1666227.45833 with a remaining 8e-06.
