70818650 ÷ 817 
We're looking to find how many times 817 goes into 70818650.

Moving on to step 1:
817 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 817

Going ahead to step 2:
If we divide 70 by 817, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (8) from the dividend to 70 and continue with: 708 / 817

Step 3:
The number 817 fits into 708 0 times, leaving a remainder of 708.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 708 to get 708.
Bring next digit (1) of the dividend behind the 708 and repeat the process: 7081 / 817

Moving on to step 4:
If we divide 7081 by 817, we get 8 and a remainder of 545.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6536 from 7081, we get 545.
Grab the next digit (8) from the dividend, add it to 545, then carry on: 5458 / 817

Let's proceed to step 5:
817 goes into 5458 6 times with a remainder of 556.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 4902 from 5458 and we're left with 556.
Take the next digit (6) from the dividend and append it to 556, then repeat: 5566 / 817

Advancing to step 6:
The number 817 fits into 5566 6 times, leaving a remainder of 664.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
Deduct 4902 from 5566 and we're left with 664.
Append the next digit (5) from the dividend to 664 and continue with: 6645 / 817

Step 7:
The number 817 fits into 6645 8 times, leaving a remainder of 109.
Record the quotient 8 as the next digit in the result. 
Result so far: 8668.0
Deduct 6536 from 6645 and we're left with 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 817

On to step 8:
When dividing 1090 by 817, we get 1 with a remainder of 273.
Use 1 as the next digit of our solution. 
Result so far: 86681.0
Subtracting 817 from 1090 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 9:
817 can be fit into 2730 3 times, resulting in a remainder of 279.
Put 3 as the next digit of the answer. 
Result so far: 86681.3
If we subtract 2451 from 2730, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 10:
The number 817 fits into 2790 3 times, leaving a remainder of 339.
Use 3 as the next digit of our solution. 
Result so far: 86681.33
If we take 2451 away from 2790, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

After the division, we end up with 86681.33 and a remainder of 0.339.
