Going ahead to step 5:
438 can be fit into 4330 9 times, resulting in a remainder of 388.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we subtract 3942 from 4330, we get 388.
Bring next digit (1) of the dividend behind the 388 and repeat the process: 3881 / 438

Step 6:
438 goes into 3881 8 times with a remainder of 377.
Use 8 as the next digit of our solution. 
Result so far: 898.0
Deduct 3504 from 3881 and we're left with 377.
Fetch the next digit (4) from the dividend, attach it to 377 and continue: 3774 / 438

Moving on to step 7:
If we divide 3774 by 438, we get 8 and a remainder of 270.
The next digit of our result is 8. 
Result so far: 8988.0
If we subtract 3504 from 3774, we get 270.
Fetch the next digit (4) from the dividend, attach it to 270 and continue: 2704 / 438

On to step 8:
The number 438 fits into 2704 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 89886.0
If we subtract 2628 from 2704, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
When dividing 760 by 438, we get 1 with a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 89886.1
Deduct 438 from 760 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 10:
3220 divided by 438 is 7 with a remainder of 154.
The next digit of our result is 7. 
Result so far: 89886.17
The remainder is 154 after subtracting 3066 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 11:
438 can be fit into 1540 3 times, resulting in a remainder of 226.
The next digit of our result is 3. 
Result so far: 89886.173
If we subtract 1314 from 1540, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 12:
2260 divided by 438 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 89886.1735
Subtract 2190 from 2260 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
700 divided by 438 is 1 with a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 89886.17351
If we subtract 438 from 700, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 14:
When dividing 2620 by 438, we get 5 with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 89886.173515
Subtracting 2190 from 2620 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 15:
438 goes into 4300 9 times with a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 89886.1735159
Deduct 3942 from 4300 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 16:
The number 438 fits into 3580 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 89886.17351598
Subtract 3504 from 3580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 89886.17351598, with a leftover of 7.6e-08.
