We're dividing 77970448 by 517 
We want to divide 77970448 by 517.

Let's proceed to step 1:
517 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 517

Advancing to step 2:
77 divided by 517 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 517

Going ahead to step 3:
When dividing 779 by 517, we get 1 with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 517 from 779 to get 262.
Include the next digit (7) from the dividend after 262, then repeat: 2627 / 517

On to step 4:
When dividing 2627 by 517, we get 5 with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2585 from 2627 to get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 517

Going ahead to step 5:
517 goes into 420 0 times with a remainder of 420.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 420 after subtracting 0 from 420.
Fetch the next digit (4) from the dividend, attach it to 420 and continue: 4204 / 517

Going ahead to step 6:
517 goes into 4204 8 times with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 1508.0
If we take 4136 away from 4204, we end up with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 517

Moving on to step 7:
517 can be fit into 684 1 times, resulting in a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 15081.0
The remainder is 167 after subtracting 517 from 684.
Include the next digit (8) from the dividend after 167, then repeat: 1678 / 517

Moving on to step 8:
If we divide 1678 by 517, we get 3 and a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 150813.0
If we subtract 1551 from 1678, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
If we divide 1270 by 517, we get 2 and a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 150813.2
If we subtract 1034 from 1270, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
517 can be fit into 2360 4 times, resulting in a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 150813.24
If we subtract 2068 from 2360, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
When dividing 2920 by 517, we get 5 with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 150813.245
If we take 2585 away from 2920, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 12:
3350 divided by 517 is 6 with a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 150813.2456
Deduct 3102 from 3350 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
517 goes into 2480 4 times with a remainder of 412.
Write down 4 as next digit of the result. 
Result so far: 150813.24564
The remainder is 412 after subtracting 2068 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 14:
517 goes into 4120 7 times with a remainder of 501.
Record the quotient 7 as the next digit in the result. 
Result so far: 150813.245647
If we take 3619 away from 4120, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Going ahead to step 15:
517 can be fit into 5010 9 times, resulting in a remainder of 357.
Write down 9 as next digit of the result. 
Result so far: 150813.2456479
Subtract 4653 from 5010 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 16:
517 can be fit into 3570 6 times, resulting in a remainder of 468.
The number 6 becomes the next digit in our result. 
Result so far: 150813.24564796
Deduct 3102 from 3570 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Our division results in 150813.24564796 with a remaining 4.68e-07.
