We're dividing 70393615 by 817 
We're looking to find how many times 817 goes into 70393615.

Moving on to step 1:
7 divided by 817 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 817

Advancing to step 2:
If we divide 70 by 817, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 817

On to step 3:
If we divide 703 by 817, we get 0 and a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 703 to get 703.
Fetch the next digit (9) from the dividend, attach it to 703 and continue: 7039 / 817

On to step 4:
When dividing 7039 by 817, we get 8 with a remainder of 503.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6536 from 7039 to get 503.
Fetch the next digit (3) from the dividend, attach it to 503 and continue: 5033 / 817

Let's proceed to step 5:
817 can be fit into 5033 6 times, resulting in a remainder of 131.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 4902 from 5033 to get 131.
Fetch the next digit (6) from the dividend, attach it to 131 and continue: 1316 / 817

Advancing to step 6:
1316 divided by 817 is 1 with a remainder of 499.
The number 1 becomes the next digit in our result. 
Result so far: 861.0
If we take 817 away from 1316, we end up with 499.
Fetch the next digit (1) from the dividend, attach it to 499 and continue: 4991 / 817

Advancing to step 7:
When dividing 4991 by 817, we get 6 with a remainder of 89.
Put 6 as the next digit of the answer. 
Result so far: 8616.0
The remainder is 89 after subtracting 4902 from 4991.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 817

Step 8:
895 divided by 817 is 1 with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 86161.0
If we subtract 817 from 895, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
817 can be fit into 780 0 times, resulting in a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 86161.0
Subtract 0 from 780 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 10:
7800 divided by 817 is 9 with a remainder of 447.
Record the quotient 9 as the next digit in the result. 
Result so far: 86161.09
Subtracting 7353 from 7800 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 11:
If we divide 4470 by 817, we get 5 and a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 86161.095
Subtracting 4085 from 4470 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
If we divide 3850 by 817, we get 4 and a remainder of 582.
Use 4 as the next digit of our solution. 
Result so far: 86161.0954
If we take 3268 away from 3850, we end up with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 13:
If we divide 5820 by 817, we get 7 and a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 86161.09547
Subtract 5719 from 5820 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 14:
The number 817 fits into 1010 1 times, leaving a remainder of 193.
The next digit of our result is 1. 
Result so far: 86161.095471
Deduct 817 from 1010 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 15:
If we divide 1930 by 817, we get 2 and a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 86161.0954712
The remainder is 296 after subtracting 1634 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 16:
817 can be fit into 2960 3 times, resulting in a remainder of 509.
The number 3 becomes the next digit in our result. 
Result so far: 86161.09547123
Subtract 2451 from 2960 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

After the division, we end up with 86161.09547123 and a remainder of 5.09e-07.
