448510 divided by 70 
We want to figure out the number of times 448510 can be divided by 70.

On to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 70

Moving on to step 2:
If we divide 44 by 70, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 70

Moving on to step 3:
The number 70 fits into 448 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 28 after subtracting 420 from 448.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 70

Moving on to step 4:
The number 70 fits into 285 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 280 from 285 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 70

On to step 5:
When dividing 51 by 70, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 640.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 70

On to step 6:
510 divided by 70 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 6407.0
Subtract 490 from 510 to 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.

Let's proceed to step 7:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 6407.2
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.

Advancing to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 6407.28
Deduct 560 from 600 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.

Going ahead to step 9:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 6407.285
Subtract 350 from 400 to 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.

On to step 10:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 6407.2857
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.

Going ahead to step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 6407.28571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 6407.285714
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 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 6407.2857142
Deduct 140 from 200 and we're left 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.

Advancing to step 14:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 6407.28571428
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.

The final result is 6407.28571428 with a remainder of 4e-08.
