30386298 ÷ 70 
Let's see how many times 70 fits into 30386298.

Moving on to step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 70

On to step 2:
If we divide 30 by 70, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 70

On to step 3:
70 goes into 303 4 times with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 280 from 303 leaves us with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 70

Moving on to step 4:
70 goes into 238 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 28 after subtracting 210 from 238.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 70

Let's proceed to step 5:
The number 70 fits into 286 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 434.0
If we take 280 away from 286, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 70

Step 6:
70 goes into 62 0 times with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 4340.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 70

Step 7:
If we divide 629 by 70, we get 8 and a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 43408.0
Subtracting 560 from 629 leaves us with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 70

Moving on to step 8:
70 goes into 698 9 times with a remainder of 68.
The next digit of our result is 9. 
Result so far: 434089.0
The remainder is 68 after subtracting 630 from 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
680 divided by 70 is 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 434089.9
If we take 630 away from 680, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 434089.97
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 434089.971
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 434089.9714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 434089.97142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 434089.971428
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 434089.9714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 434089.97142857
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 434089.97142857 with a balance of 1e-08.
