We're dividing 23842439 by 438 
Let's see how many times 438 fits into 23842439.

Let's proceed to step 1:
The number 438 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 438

Advancing to step 2:
The number 438 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 438

On to step 3:
If we divide 238 by 438, we get 0 and a remainder of 238.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 238, we end up with 238.
Append the next digit (4) from the dividend to 238 and continue with: 2384 / 438

Advancing to step 4:
The number 438 fits into 2384 5 times, leaving a remainder of 194.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2190 from 2384, we get 194.
Include the next digit (2) from the dividend after 194, then repeat: 1942 / 438

Step 5:
When dividing 1942 by 438, we get 4 with a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 1752 from 1942, we get 190.
Fetch the next digit (4) from the dividend, attach it to 190 and continue: 1904 / 438

Step 6:
When dividing 1904 by 438, we get 4 with a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
Subtract 1752 from 1904 to get 152.
Grab the next digit (3) from the dividend, add it to 152, then carry on: 1523 / 438

Moving on to step 7:
438 goes into 1523 3 times with a remainder of 209.
The next digit of our result is 3. 
Result so far: 5443.0
Subtracting 1314 from 1523 leaves us with 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 438

Moving on to step 8:
438 can be fit into 2099 4 times, resulting in a remainder of 347.
The number 4 becomes the next digit in our result. 
Result so far: 54434.0
The remainder is 347 after subtracting 1752 from 2099.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Going ahead to step 9:
438 goes into 3470 7 times with a remainder of 404.
The number 7 becomes the next digit in our result. 
Result so far: 54434.7
If we subtract 3066 from 3470, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 10:
If we divide 4040 by 438, we get 9 and a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 54434.79
Deduct 3942 from 4040 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 11:
438 goes into 980 2 times with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 54434.792
If we subtract 876 from 980, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
The number 438 fits into 1040 2 times, leaving a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 54434.7922
Subtracting 876 from 1040 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 54434.7922 and a remainder of 0.00164.
