452140 ÷ 70 
We're looking to find how many times 70 goes into 452140.

Step 1:
4 divided by 70 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 70

Let's proceed to step 2:
When dividing 45 by 70, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 70

Let's proceed to step 3:
70 goes into 452 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 32 after subtracting 420 from 452.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 70

Going ahead to step 4:
321 divided by 70 is 4 with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 280 away from 321, we end up with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 70

Advancing to step 5:
414 divided by 70 is 5 with a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
Deduct 350 from 414 and we're left with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 70

Moving on to step 6:
70 can be fit into 640 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 6459.0
The remainder is 10 after subtracting 630 from 640.
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 7:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 6459.1
The remainder is 30 after subtracting 70 from 100.
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 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 6459.14
Subtracting 280 from 300 leaves us 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.

Let's proceed to step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 6459.142
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.

Step 10:
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: 6459.1428
The remainder is 40 after subtracting 560 from 600.
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 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6459.14285
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.

Let's proceed to step 12:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 6459.142857
If we take 490 away from 500, we end up 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.

Step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 6459.1428571
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.

Moving on to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 6459.14285714
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.

In conclusion, the division gives 6459.14285714 with a balance of 2e-08.
