Let's divide 30213096 by 405
We're looking to find how many times 405 goes into 30213096.

Going ahead to step 1:
The number 405 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 405

On to step 2:
If we divide 30 by 405, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 405

Let's proceed to step 3:
405 goes into 302 0 times with a remainder of 302.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 302 after subtracting 0 from 302.
Grab the next digit (1) from the dividend, add it to 302, then carry on: 3021 / 405

Moving on to step 4:
3021 divided by 405 is 7 with a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 2835 away from 3021, we end up with 186.
Bring next digit (3) of the dividend behind the 186 and repeat the process: 1863 / 405

Moving on to step 5:
405 goes into 1863 4 times with a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 1620 from 1863 to get 243.
Fetch the next digit (0) from the dividend, attach it to 243 and continue: 2430 / 405

On to step 6:
If we divide 2430 by 405, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 746.0
Deduct 2430 from 2430 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 405

Advancing to step 7:
The number 405 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 7460.0
Subtract 0 from 9 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 405

Step 8:
When dividing 96 by 405, we get 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 74600.0
The remainder is 96 after subtracting 0 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
405 goes into 960 2 times with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 74600.2
Deduct 810 from 960 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
1500 divided by 405 is 3 with a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 74600.23
If we subtract 1215 from 1500, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 11:
405 goes into 2850 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 74600.237
Subtract 2835 from 2850 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 405, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 74600.237
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
When dividing 1500 by 405, we get 3 with a remainder of 285.
Put 3 as the next digit of the answer. 
Result so far: 74600.23703
Subtract 1215 from 1500 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 14:
When dividing 2850 by 405, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 74600.237037
If we subtract 2835 from 2850, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
The number 405 fits into 150 0 times, leaving a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 74600.237037
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
When dividing 1500 by 405, we get 3 with a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 74600.23703703
If we take 1215 away from 1500, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

In conclusion, the division gives 74600.23703703 with a balance of 2.85e-07.
