We look at the division of 30459809 by 807 
We want to divide 30459809 by 807.

Let's proceed to step 1:
When dividing 3 by 807, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 807

On to step 2:
The number 807 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 807

Step 3:
If we divide 304 by 807, we get 0 and a remainder of 304.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Include the next digit (5) from the dividend after 304, then repeat: 3045 / 807

Step 4:
If we divide 3045 by 807, we get 3 and a remainder of 624.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2421 from 3045 and we're left with 624.
Append the next digit (9) from the dividend to 624 and continue with: 6249 / 807

Going ahead to step 5:
If we divide 6249 by 807, we get 7 and a remainder of 600.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 5649 away from 6249, we end up with 600.
Append the next digit (8) from the dividend to 600 and continue with: 6008 / 807

Moving on to step 6:
If we divide 6008 by 807, we get 7 and a remainder of 359.
Put 7 as the next digit of the answer. 
Result so far: 377.0
Subtracting 5649 from 6008 leaves us with 359.
Grab the next digit (0) from the dividend, add it to 359, then carry on: 3590 / 807

Moving on to step 7:
807 goes into 3590 4 times with a remainder of 362.
Write down 4 as next digit of the result. 
Result so far: 3774.0
The remainder is 362 after subtracting 3228 from 3590.
Fetch the next digit (9) from the dividend, attach it to 362 and continue: 3629 / 807

On to step 8:
The number 807 fits into 3629 4 times, leaving a remainder of 401.
The number 4 becomes the next digit in our result. 
Result so far: 37744.0
Subtract 3228 from 3629 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
The number 807 fits into 4010 4 times, leaving a remainder of 782.
Put 4 as the next digit of the answer. 
Result so far: 37744.4
Deduct 3228 from 4010 and we're left with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Advancing to step 10:
7820 divided by 807 is 9 with a remainder of 557.
The number 9 becomes the next digit in our result. 
Result so far: 37744.49
Subtract 7263 from 7820 to get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 11:
The number 807 fits into 5570 6 times, leaving a remainder of 728.
Write down 6 as next digit of the result. 
Result so far: 37744.496
If we subtract 4842 from 5570, we get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 12:
807 goes into 7280 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 37744.4969
If we take 7263 away from 7280, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
When dividing 170 by 807, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 37744.4969
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
807 can be fit into 1700 2 times, resulting in a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 37744.496902
If we take 1614 away from 1700, we end up 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.

Advancing to step 15:
860 divided by 807 is 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 37744.4969021
Deduct 807 from 860 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 16:
If we divide 530 by 807, we get 0 and a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 37744.4969021
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

In conclusion, the division gives 37744.4969021 with a balance of 5.3e-07.
