429630 ÷ 70 
We want to figure out the number of times 429630 can be divided by 70.

On to step 1:
The number 70 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 70

On to step 2:
If we divide 42 by 70, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 70

Going ahead to step 3:
70 can be fit into 429 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 9 after subtracting 420 from 429.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 70

Going ahead to step 4:
When dividing 96 by 70, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 70 from 96 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 70

Moving on to step 5:
70 can be fit into 263 3 times, resulting in a remainder of 53.
The next digit of our result is 3. 
Result so far: 613.0
Subtracting 210 from 263 leaves us with 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 70

Step 6:
If we divide 530 by 70, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 6137.0
Deduct 490 from 530 and we're left 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.

Step 7:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 6137.5
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.

Step 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 6137.57
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.

Advancing to step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 6137.571
Subtracting 70 from 100 leaves us 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.

Let's proceed to step 10:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6137.5714
Deduct 280 from 300 and we're left 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.

Moving on to step 11:
If we divide 200 by 70, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 6137.57142
Subtracting 140 from 200 leaves us with 60.
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 12:
70 goes into 600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 6137.571428
If we subtract 560 from 600, we get 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 13:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 6137.5714285
Subtracting 350 from 400 leaves us 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.

Let's proceed to step 14:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 6137.57142857
Subtracting 490 from 500 leaves us 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.

The final outcome is 6137.57142857, with a leftover of 1e-08.
