Let's divide 70319053 by 813
Our goal is to divide 70319053 by 813.

On to step 1:
If we divide 7 by 813, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 813

On to step 2:
813 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 813

Advancing to step 3:
703 divided by 813 is 0 with a remainder of 703.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 703 after subtracting 0 from 703.
Fetch the next digit (1) from the dividend, attach it to 703 and continue: 7031 / 813

Moving on to step 4:
813 goes into 7031 8 times with a remainder of 527.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6504 from 7031 and we're left with 527.
Fetch the next digit (9) from the dividend, attach it to 527 and continue: 5279 / 813

Advancing to step 5:
813 can be fit into 5279 6 times, resulting in a remainder of 401.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 401 after subtracting 4878 from 5279.
Bring next digit (0) of the dividend behind the 401 and repeat the process: 4010 / 813

On to step 6:
813 goes into 4010 4 times with a remainder of 758.
Put 4 as the next digit of the answer. 
Result so far: 864.0
The remainder is 758 after subtracting 3252 from 4010.
Append the next digit (5) from the dividend to 758 and continue with: 7585 / 813

Step 7:
7585 divided by 813 is 9 with a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 8649.0
If we take 7317 away from 7585, we end up with 268.
Append the next digit (3) from the dividend to 268 and continue with: 2683 / 813

Going ahead to step 8:
When dividing 2683 by 813, we get 3 with a remainder of 244.
The number 3 becomes the next digit in our result. 
Result so far: 86493.0
The remainder is 244 after subtracting 2439 from 2683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 9:
813 can be fit into 2440 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 86493.3
Subtracting 2439 from 2440 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 813, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 86493.3
Deduct 0 from 10 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.

Step 11:
813 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 86493.3
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 86493.3 with a remainder of 0.01.
