820450 divided by 70 
Let's see how many times 70 fits into 820450.

Going ahead to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 70

Going ahead to step 2:
If we divide 82 by 70, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 70 from 82.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 70

On to step 3:
If we divide 120 by 70, we get 1 and a remainder of 50.
The next digit of our result is 1. 
Result so far: 11.0
If we take 70 away from 120, we end up with 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 70

Moving on to step 4:
504 divided by 70 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
The remainder is 14 after subtracting 490 from 504.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 70

Advancing to step 5:
The number 70 fits into 145 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 1172.0
The remainder is 5 after subtracting 140 from 145.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 70

Let's proceed to step 6:
50 divided by 70 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11720.0
Deduct 0 from 50 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.

Going ahead to step 7:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 11720.7
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11720.71
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.

On to step 9:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 11720.714
Subtract 280 from 300 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.

Going ahead to step 10:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 11720.7142
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.

On to step 11:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 11720.71428
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 12:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 11720.714285
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.

Going ahead to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 11720.7142857
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 14:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11720.71428571
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.

After the division, we end up with 11720.71428571 and a remainder of 3e-08.
