We look at the division of 30873533 by 684 
Our goal is to divide 30873533 by 684.

Step 1:
684 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 684

Moving on to step 2:
684 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 684

Moving on to step 3:
When dividing 308 by 684, we get 0 with a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 308 after subtracting 0 from 308.
Include the next digit (7) from the dividend after 308, then repeat: 3087 / 684

On to step 4:
684 goes into 3087 4 times with a remainder of 351.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2736 from 3087, we get 351.
Take the next digit (3) from the dividend and append it to 351, then repeat: 3513 / 684

Let's proceed to step 5:
684 can be fit into 3513 5 times, resulting in a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 3420 from 3513 leaves us with 93.
Fetch the next digit (5) from the dividend, attach it to 93 and continue: 935 / 684

Let's proceed to step 6:
When dividing 935 by 684, we get 1 with a remainder of 251.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
Subtract 684 from 935 to get 251.
Append the next digit (3) from the dividend to 251 and continue with: 2513 / 684

Let's proceed to step 7:
When dividing 2513 by 684, we get 3 with a remainder of 461.
Record the quotient 3 as the next digit in the result. 
Result so far: 4513.0
The remainder is 461 after subtracting 2052 from 2513.
Fetch the next digit (3) from the dividend, attach it to 461 and continue: 4613 / 684

Moving on to step 8:
The number 684 fits into 4613 6 times, leaving a remainder of 509.
Use 6 as the next digit of our solution. 
Result so far: 45136.0
If we take 4104 away from 4613, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 9:
The number 684 fits into 5090 7 times, leaving a remainder of 302.
The next digit of our result is 7. 
Result so far: 45136.7
Subtract 4788 from 5090 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 10:
684 goes into 3020 4 times with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 45136.74
Deduct 2736 from 3020 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
When dividing 2840 by 684, we get 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 45136.744
Subtract 2736 from 2840 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 45136.744 with a balance of 0.0104.
