70717815 ÷ 511 
We want to divide 70717815 by 511.

Advancing to step 1:
511 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 511

Advancing to step 2:
70 divided by 511 is 0 with 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.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 511

Advancing to step 3:
511 goes into 707 1 times with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 511 away from 707, we end up with 196.
Include the next digit (1) from the dividend after 196, then repeat: 1961 / 511

Advancing to step 4:
511 goes into 1961 3 times with a remainder of 428.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1533 from 1961 leaves us with 428.
Fetch the next digit (7) from the dividend, attach it to 428 and continue: 4287 / 511

Let's proceed to step 5:
511 goes into 4287 8 times with a remainder of 199.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we take 4088 away from 4287, we end up with 199.
Append the next digit (8) from the dividend to 199 and continue with: 1998 / 511

On to step 6:
511 can be fit into 1998 3 times, resulting in a remainder of 465.
The next digit of our result is 3. 
Result so far: 1383.0
Deduct 1533 from 1998 and we're left with 465.
Include the next digit (1) from the dividend after 465, then repeat: 4651 / 511

On to step 7:
The number 511 fits into 4651 9 times, leaving a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 13839.0
Deduct 4599 from 4651 and we're left with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 511

Advancing to step 8:
If we divide 525 by 511, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 138391.0
Subtracting 511 from 525 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
If we divide 140 by 511, we get 0 and a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 138391.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
511 goes into 1400 2 times with a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 138391.02
Subtracting 1022 from 1400 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 11:
511 goes into 3780 7 times with a remainder of 203.
Record the quotient 7 as the next digit in the result. 
Result so far: 138391.027
If we subtract 3577 from 3780, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
When dividing 2030 by 511, we get 3 with a remainder of 497.
The number 3 becomes the next digit in our result. 
Result so far: 138391.0273
If we subtract 1533 from 2030, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 13:
511 goes into 4970 9 times with a remainder of 371.
Use 9 as the next digit of our solution. 
Result so far: 138391.02739
Subtracting 4599 from 4970 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 14:
511 can be fit into 3710 7 times, resulting in a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 138391.027397
The remainder is 133 after subtracting 3577 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 15:
The number 511 fits into 1330 2 times, leaving a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 138391.0273972
Subtract 1022 from 1330 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 16:
511 can be fit into 3080 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 138391.02739726
If we subtract 3066 from 3080, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 138391.02739726 with a balance of 1.4e-08.
