We look at the division of 30306250 by 407 
We're looking to find how many times 407 goes into 30306250.

Advancing to step 1:
407 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 407

Advancing to step 2:
When dividing 30 by 407, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 407

Advancing to step 3:
407 can be fit into 303 0 times, resulting in a remainder of 303.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 303 to get 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 407

Going ahead to step 4:
When dividing 3030 by 407, we get 7 with a remainder of 181.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 181 after subtracting 2849 from 3030.
Grab the next digit (6) from the dividend, add it to 181, then carry on: 1816 / 407

Let's proceed to step 5:
When dividing 1816 by 407, we get 4 with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 1628 from 1816 leaves us with 188.
Append the next digit (2) from the dividend to 188 and continue with: 1882 / 407

Going ahead to step 6:
407 can be fit into 1882 4 times, resulting in a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 744.0
If we take 1628 away from 1882, we end up with 254.
Bring next digit (5) of the dividend behind the 254 and repeat the process: 2545 / 407

On to step 7:
When dividing 2545 by 407, we get 6 with a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 7446.0
Subtracting 2442 from 2545 leaves us with 103.
Grab the next digit (0) from the dividend, add it to 103, then carry on: 1030 / 407

Going ahead to step 8:
The number 407 fits into 1030 2 times, leaving a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 74462.0
Deduct 814 from 1030 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 9:
407 can be fit into 2160 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 74462.5
If we subtract 2035 from 2160, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 10:
The number 407 fits into 1250 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 74462.53
The remainder is 29 after subtracting 1221 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
407 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 74462.53
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 12:
When dividing 2900 by 407, we get 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 74462.5307
If we subtract 2849 from 2900, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 13:
The number 407 fits into 510 1 times, leaving a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 74462.53071
Subtract 407 from 510 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 14:
The number 407 fits into 1030 2 times, leaving a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 74462.530712
If we subtract 814 from 1030, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 15:
If we divide 2160 by 407, we get 5 and a remainder of 125.
The next digit of our result is 5. 
Result so far: 74462.5307125
The remainder is 125 after subtracting 2035 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 16:
If we divide 1250 by 407, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 74462.53071253
Deduct 1221 from 1250 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 74462.53071253 with a balance of 2.9e-08.
