3830431 ÷ 438 
We want to divide 3830431 by 438.

On to step 1:
438 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 438

Going ahead to step 2:
If we divide 38 by 438, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 438

On to step 3:
If we divide 383 by 438, we get 0 and a remainder of 383.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 383, we end up with 383.
Take the next digit (0) from the dividend and append it to 383, then repeat: 3830 / 438

Advancing to step 4:
The number 438 fits into 3830 8 times, leaving a remainder of 326.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3504 from 3830 leaves us with 326.
Append the next digit (4) from the dividend to 326 and continue with: 3264 / 438

Moving on to step 5:
438 goes into 3264 7 times with a remainder of 198.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 3066 from 3264, we get 198.
Bring next digit (3) of the dividend behind the 198 and repeat the process: 1983 / 438

Step 6:
438 goes into 1983 4 times with a remainder of 231.
Write down 4 as next digit of the result. 
Result so far: 874.0
Subtract 1752 from 1983 to get 231.
Fetch the next digit (1) from the dividend, attach it to 231 and continue: 2311 / 438

Going ahead to step 7:
When dividing 2311 by 438, we get 5 with a remainder of 121.
The number 5 becomes the next digit in our result. 
Result so far: 8745.0
The remainder is 121 after subtracting 2190 from 2311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 8:
When dividing 1210 by 438, we get 2 with a remainder of 334.
Put 2 as the next digit of the answer. 
Result so far: 8745.2
If we take 876 away from 1210, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 9:
3340 divided by 438 is 7 with a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 8745.27
If we subtract 3066 from 3340, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 10:
2740 divided by 438 is 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 8745.276
Deduct 2628 from 2740 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.

Step 11:
438 can be fit into 1120 2 times, resulting in a remainder of 244.
The next digit of our result is 2. 
Result so far: 8745.2762
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.

Advancing to step 12:
2440 divided by 438 is 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 8745.27625
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.

Advancing to step 13:
The number 438 fits into 2500 5 times, leaving a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 8745.276255
If we take 2190 away from 2500, we end up 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.

Our division results in 8745.276255 with a remaining 3.1e-05.
