Let's divide 30931538 by 423
Our goal is to divide 30931538 by 423.

Let's proceed to step 1:
The number 423 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 423

Advancing to step 2:
When dividing 30 by 423, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 423

Moving on to step 3:
309 divided by 423 is 0 with a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 309 after subtracting 0 from 309.
Include the next digit (3) from the dividend after 309, then repeat: 3093 / 423

Going ahead to step 4:
The number 423 fits into 3093 7 times, leaving a remainder of 132.
The next digit of our result is 7. 
Result so far: 7.0
If we take 2961 away from 3093, we end up with 132.
Bring next digit (1) of the dividend behind the 132 and repeat the process: 1321 / 423

Let's proceed to step 5:
When dividing 1321 by 423, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 1269 away from 1321, we end up with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 423

On to step 6:
If we divide 525 by 423, we get 1 and a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
If we subtract 423 from 525, we get 102.
Append the next digit (3) from the dividend to 102 and continue with: 1023 / 423

Moving on to step 7:
423 can be fit into 1023 2 times, resulting in a remainder of 177.
Put 2 as the next digit of the answer. 
Result so far: 7312.0
Deduct 846 from 1023 and we're left with 177.
Append the next digit (8) from the dividend to 177 and continue with: 1778 / 423

Moving on to step 8:
423 goes into 1778 4 times with a remainder of 86.
The next digit of our result is 4. 
Result so far: 73124.0
Deduct 1692 from 1778 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
The number 423 fits into 860 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 73124.2
Deduct 846 from 860 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
The number 423 fits into 140 0 times, leaving a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 73124.2
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
1400 divided by 423 is 3 with a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 73124.203
Deduct 1269 from 1400 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 12:
If we divide 1310 by 423, we get 3 and a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 73124.2033
Subtracting 1269 from 1310 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 73124.2033 with a balance of 0.00041.
