We divide 3785689 by 438
Our goal is to divide 3785689 by 438.

Moving on to step 1:
3 divided by 438 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 438

Moving on to step 2:
37 divided by 438 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 438

Step 3:
When dividing 378 by 438, we get 0 with a remainder of 378.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 378 after subtracting 0 from 378.
Fetch the next digit (5) from the dividend, attach it to 378 and continue: 3785 / 438

Let's proceed to step 4:
3785 divided by 438 is 8 with a remainder of 281.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 281 after subtracting 3504 from 3785.
Append the next digit (6) from the dividend to 281 and continue with: 2816 / 438

Advancing to step 5:
The number 438 fits into 2816 6 times, leaving a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 2628 from 2816 leaves us with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 438

On to step 6:
The number 438 fits into 1888 4 times, leaving a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 864.0
Deduct 1752 from 1888 and we're left with 136.
Bring next digit (9) of the dividend behind the 136 and repeat the process: 1369 / 438

Going ahead to step 7:
438 goes into 1369 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 8643.0
Deduct 1314 from 1369 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
438 goes into 550 1 times with a remainder of 112.
Write down 1 as next digit of the result. 
Result so far: 8643.1
Deduct 438 from 550 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
If we divide 1120 by 438, we get 2 and a remainder of 244.
The next digit of our result is 2. 
Result so far: 8643.12
Subtracting 876 from 1120 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 10:
If we divide 2440 by 438, we get 5 and a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 8643.125
If we subtract 2190 from 2440, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
If we divide 2500 by 438, we get 5 and a remainder of 310.
The next digit of our result is 5. 
Result so far: 8643.1255
Deduct 2190 from 2500 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 8643.1255 and a remainder of 0.0031.
