306411 ÷ 70 
We're looking to find how many times 70 goes into 306411.

On to step 1:
3 divided by 70 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 70

On to step 2:
When dividing 30 by 70, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 70

Step 3:
If we divide 306 by 70, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 26 after subtracting 280 from 306.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 70

Going ahead to step 4:
70 goes into 264 3 times with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 54 after subtracting 210 from 264.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 70

Step 5:
When dividing 541 by 70, we get 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 437.0
Deduct 490 from 541 and we're left with 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 70

Moving on to step 6:
511 divided by 70 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 4377.0
If we subtract 490 from 511, we 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.

Advancing to step 7:
70 can be fit into 210 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 4377.3
Deduct 210 from 210 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 70 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4377.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
70 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4377.3
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4377.3, and the remainder is 0.0.
