On to step 1:
8 divided by 438 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 438

Advancing to step 2:
438 can be fit into 82 0 times, resulting in a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 438

Let's proceed to step 3:
438 can be fit into 826 1 times, resulting in a remainder of 388.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 438 from 826 leaves us with 388.
Append the next digit (1) from the dividend to 388 and continue with: 3881 / 438

Advancing to step 4:
3881 divided by 438 is 8 with a remainder of 377.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3504 from 3881 and we're left with 377.
Include the next digit (7) from the dividend after 377, then repeat: 3777 / 438

Moving on to step 5:
3777 divided by 438 is 8 with a remainder of 273.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtract 3504 from 3777 to get 273.
Append the next digit (3) from the dividend to 273 and continue with: 2733 / 438

Moving on to step 6:
When dividing 2733 by 438, we get 6 with a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 1886.0
Subtract 2628 from 2733 to get 105.
Append the next digit (9) from the dividend to 105 and continue with: 1059 / 438

On to step 7:
The number 438 fits into 1059 2 times, leaving a remainder of 183.
Record the quotient 2 as the next digit in the result. 
Result so far: 18862.0
If we subtract 876 from 1059, we get 183.
Fetch the next digit (0) from the dividend, attach it to 183 and continue: 1830 / 438

Advancing to step 8:
The number 438 fits into 1830 4 times, leaving a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 188624.0
Subtract 1752 from 1830 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 438 is 1 with a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 188624.1
Subtract 438 from 780 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 10:
438 can be fit into 3420 7 times, resulting in a remainder of 354.
The number 7 becomes the next digit in our result. 
Result so far: 188624.17
The remainder is 354 after subtracting 3066 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 11:
The number 438 fits into 3540 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 188624.178
The remainder is 36 after subtracting 3504 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
438 can be fit into 360 0 times, resulting in a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 188624.178
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
438 can be fit into 3600 8 times, resulting in a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 188624.17808
Subtracting 3504 from 3600 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
If we divide 960 by 438, we get 2 and a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 188624.178082
Subtract 876 from 960 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
840 divided by 438 is 1 with a remainder of 402.
The next digit of our result is 1. 
Result so far: 188624.1780821
If we take 438 away from 840, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 16:
If we divide 4020 by 438, we get 9 and a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 188624.17808219
Deduct 3942 from 4020 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 188624.17808219 with a remaining 7.8e-08.
