30870084 ÷ 609 
Our goal is to divide 30870084 by 609.

Advancing to step 1:
The number 609 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 609

Step 2:
609 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 609

Step 3:
609 goes into 308 0 times with a remainder of 308.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Append the next digit (7) from the dividend to 308 and continue with: 3087 / 609

Step 4:
When dividing 3087 by 609, we get 5 with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 42 after subtracting 3045 from 3087.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 609

Advancing to step 5:
609 goes into 420 0 times with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 420 after subtracting 0 from 420.
Fetch the next digit (0) from the dividend, attach it to 420 and continue: 4200 / 609

On to step 6:
609 can be fit into 4200 6 times, resulting in a remainder of 546.
Write down 6 as next digit of the result. 
Result so far: 506.0
If we take 3654 away from 4200, we end up with 546.
Grab the next digit (8) from the dividend, add it to 546, then carry on: 5468 / 609

On to step 7:
609 can be fit into 5468 8 times, resulting in a remainder of 596.
Put 8 as the next digit of the answer. 
Result so far: 5068.0
If we subtract 4872 from 5468, we get 596.
Grab the next digit (4) from the dividend, add it to 596, then carry on: 5964 / 609

On to step 8:
5964 divided by 609 is 9 with a remainder of 483.
Record the quotient 9 as the next digit in the result. 
Result so far: 50689.0
If we take 5481 away from 5964, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Going ahead to step 9:
609 can be fit into 4830 7 times, resulting in a remainder of 567.
Use 7 as the next digit of our solution. 
Result so far: 50689.7
If we take 4263 away from 4830, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 10:
5670 divided by 609 is 9 with a remainder of 189.
Write down 9 as next digit of the result. 
Result so far: 50689.79
If we subtract 5481 from 5670, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 11:
1890 divided by 609 is 3 with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 50689.793
Deduct 1827 from 1890 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
630 divided by 609 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 50689.7931
Subtract 609 from 630 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
The number 609 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 50689.7931
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
609 can be fit into 2100 3 times, resulting in a remainder of 273.
Put 3 as the next digit of the answer. 
Result so far: 50689.793103
Subtract 1827 from 2100 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 15:
2730 divided by 609 is 4 with a remainder of 294.
Use 4 as the next digit of our solution. 
Result so far: 50689.7931034
Subtract 2436 from 2730 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 16:
If we divide 2940 by 609, we get 4 and a remainder of 504.
The number 4 becomes the next digit in our result. 
Result so far: 50689.79310344
Subtract 2436 from 2940 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 50689.79310344 with a remainder of 5.04e-07.
