809835 ÷ 70 
Let's see how many times 70 fits into 809835.

Going ahead to step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 70

Going ahead to step 2:
When dividing 80 by 70, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 10 after subtracting 70 from 80.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 70

Step 3:
When dividing 109 by 70, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 39 after subtracting 70 from 109.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 70

Step 4:
When dividing 398 by 70, we get 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 350 from 398 and we're left with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 70

Let's proceed to step 5:
When dividing 483 by 70, we get 6 with a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 1156.0
Subtract 420 from 483 to get 63.
Fetch the next digit (5) from the dividend, attach it to 63 and continue: 635 / 70

On to step 6:
635 divided by 70 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 11569.0
The remainder is 5 after subtracting 630 from 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 70, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11569.0
If we take 0 away from 50, we end up 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.

Step 8:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11569.07
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.

Going ahead to step 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 11569.071
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.

Let's proceed to step 10:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 11569.0714
If we take 280 away from 300, we end up 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.

Advancing to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11569.07142
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 12:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 11569.071428
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.

On to step 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11569.0714285
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.

Going ahead to step 14:
If we divide 500 by 70, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 11569.07142857
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.

The final outcome is 11569.07142857, with a leftover of 1e-08.
