Let's divide 729451 by 70
We want to figure out the number of times 729451 can be divided by 70.

Advancing to step 1:
7 divided by 70 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 70

Let's proceed to step 2:
When dividing 72 by 70, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 70 from 72 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 70

Let's proceed to step 3:
29 divided by 70 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 29, we get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 70

Advancing to step 4:
294 divided by 70 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 14 after subtracting 280 from 294.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 70

Advancing to step 5:
70 goes into 145 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 1042.0
Subtract 140 from 145 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 70

Going ahead to step 6:
70 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 10420.0
Subtracting 0 from 51 leaves us with 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 7:
70 goes into 510 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 10420.7
Deduct 490 from 510 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.

Step 8:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 10420.72
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.

Step 9:
If we divide 600 by 70, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 10420.728
If we take 560 away from 600, we end up 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 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10420.7285
Deduct 350 from 400 and we're left 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 11:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 10420.72857
Subtract 490 from 500 to 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.

Moving on to step 12:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 10420.728571
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.

Step 13:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 10420.7285714
If we subtract 280 from 300, we get 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 14:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 10420.72857142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 10420.72857142, with a leftover of 6e-08.
