5438623 divided by 331 
Our goal is to divide 5438623 by 331.

Advancing to step 1:
When dividing 5 by 331, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 331

Step 2:
If we divide 54 by 331, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 331

Step 3:
The number 331 fits into 543 1 times, leaving a remainder of 212.
The next digit of our result is 1. 
Result so far: 1.0
If we take 331 away from 543, we end up with 212.
Include the next digit (8) from the dividend after 212, then repeat: 2128 / 331

Going ahead to step 4:
When dividing 2128 by 331, we get 6 with a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 1986 from 2128, we get 142.
Append the next digit (6) from the dividend to 142 and continue with: 1426 / 331

Moving on to step 5:
1426 divided by 331 is 4 with a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 164.0
The remainder is 102 after subtracting 1324 from 1426.
Append the next digit (2) from the dividend to 102 and continue with: 1022 / 331

Step 6:
When dividing 1022 by 331, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 1643.0
If we take 993 away from 1022, we end up with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 331

Going ahead to step 7:
The number 331 fits into 293 0 times, leaving a remainder of 293.
Use 0 as the next digit of our solution. 
Result so far: 16430.0
If we take 0 away from 293, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 8:
331 can be fit into 2930 8 times, resulting in a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 16430.8
Subtracting 2648 from 2930 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 9:
2820 divided by 331 is 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 16430.88
Subtract 2648 from 2820 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 16430.88 and a remainder of 0.172.
