Advancing to step 9:
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: 155037.2
Deduct 876 from 1040 and we're left 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.

Let's proceed to step 10:
When dividing 1640 by 438, we get 3 with a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 155037.23
If we subtract 1314 from 1640, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 11:
The number 438 fits into 3260 7 times, leaving a remainder of 194.
The number 7 becomes the next digit in our result. 
Result so far: 155037.237
If we subtract 3066 from 3260, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 12:
The number 438 fits into 1940 4 times, leaving a remainder of 188.
The next digit of our result is 4. 
Result so far: 155037.2374
If we subtract 1752 from 1940, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 13:
The number 438 fits into 1880 4 times, leaving a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 155037.23744
Subtract 1752 from 1880 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 155037.23744, with a leftover of 0.000128.
