We divide 71805057 by 513
Our goal is to divide 71805057 by 513.

Moving on to step 1:
If we divide 7 by 513, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 513

Going ahead to step 2:
513 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 513

Step 3:
The number 513 fits into 718 1 times, leaving a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 513 from 718 and we're left with 205.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 513

Going ahead to step 4:
If we divide 2050 by 513, we get 3 and a remainder of 511.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1539 from 2050, we get 511.
Take the next digit (5) from the dividend and append it to 511, then repeat: 5115 / 513

Moving on to step 5:
The number 513 fits into 5115 9 times, leaving a remainder of 498.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 4617 from 5115 leaves us with 498.
Include the next digit (0) from the dividend after 498, then repeat: 4980 / 513

Step 6:
If we divide 4980 by 513, we get 9 and a remainder of 363.
The number 9 becomes the next digit in our result. 
Result so far: 1399.0
Subtract 4617 from 4980 to get 363.
Fetch the next digit (5) from the dividend, attach it to 363 and continue: 3635 / 513

Step 7:
513 goes into 3635 7 times with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 13997.0
If we subtract 3591 from 3635, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 513

Step 8:
513 can be fit into 447 0 times, resulting in a remainder of 447.
Put 0 as the next digit of the answer. 
Result so far: 139970.0
If we subtract 0 from 447, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 9:
4470 divided by 513 is 8 with a remainder of 366.
Use 8 as the next digit of our solution. 
Result so far: 139970.8
If we take 4104 away from 4470, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 10:
The number 513 fits into 3660 7 times, leaving a remainder of 69.
The next digit of our result is 7. 
Result so far: 139970.87
Deduct 3591 from 3660 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
513 can be fit into 690 1 times, resulting in a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 139970.871
If we subtract 513 from 690, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 12:
513 can be fit into 1770 3 times, resulting in a remainder of 231.
Write down 3 as next digit of the result. 
Result so far: 139970.8713
Deduct 1539 from 1770 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 13:
If we divide 2310 by 513, we get 4 and a remainder of 258.
The number 4 becomes the next digit in our result. 
Result so far: 139970.87134
Deduct 2052 from 2310 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 14:
If we divide 2580 by 513, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 139970.871345
If we take 2565 away from 2580, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
513 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 139970.871345
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
The number 513 fits into 1500 2 times, leaving a remainder of 474.
Record the quotient 2 as the next digit in the result. 
Result so far: 139970.87134502
If we take 1026 away from 1500, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

The final result is 139970.87134502 with a remainder of 4.74e-07.
