On to step 3:
When dividing 757 by 913, we get 0 with a remainder of 757.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 757 to get 757.
Grab the next digit (7) from the dividend, add it to 757, then carry on: 7577 / 913

On to step 4:
When dividing 7577 by 913, we get 8 with a remainder of 273.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7304 from 7577 and we're left with 273.
Append the next digit (4) from the dividend to 273 and continue with: 2734 / 913

Step 5:
2734 divided by 913 is 2 with a remainder of 908.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1826 from 2734 and we're left with 908.
Include the next digit (2) from the dividend after 908, then repeat: 9082 / 913

Let's proceed to step 6:
The number 913 fits into 9082 9 times, leaving a remainder of 865.
Record the quotient 9 as the next digit in the result. 
Result so far: 829.0
If we subtract 8217 from 9082, we get 865.
Include the next digit (0) from the dividend after 865, then repeat: 8650 / 913

Advancing to step 7:
913 goes into 8650 9 times with a remainder of 433.
Use 9 as the next digit of our solution. 
Result so far: 8299.0
The remainder is 433 after subtracting 8217 from 8650.
Bring next digit (4) of the dividend behind the 433 and repeat the process: 4334 / 913

On to step 8:
913 can be fit into 4334 4 times, resulting in a remainder of 682.
Record the quotient 4 as the next digit in the result. 
Result so far: 82994.0
Subtracting 3652 from 4334 leaves us with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 9:
If we divide 6820 by 913, we get 7 and a remainder of 429.
Record the quotient 7 as the next digit in the result. 
Result so far: 82994.7
Subtracting 6391 from 6820 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 10:
913 can be fit into 4290 4 times, resulting in a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 82994.74
If we subtract 3652 from 4290, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 11:
If we divide 6380 by 913, we get 6 and a remainder of 902.
Use 6 as the next digit of our solution. 
Result so far: 82994.746
Subtract 5478 from 6380 to get 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

On to step 12:
9020 divided by 913 is 9 with a remainder of 803.
Record the quotient 9 as the next digit in the result. 
Result so far: 82994.7469
The remainder is 803 after subtracting 8217 from 9020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Going ahead to step 13:
913 goes into 8030 8 times with a remainder of 726.
Put 8 as the next digit of the answer. 
Result so far: 82994.74698
If we take 7304 away from 8030, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Advancing to step 14:
913 goes into 7260 7 times with a remainder of 869.
The next digit of our result is 7. 
Result so far: 82994.746987
Subtract 6391 from 7260 to get 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Advancing to step 15:
If we divide 8690 by 913, we get 9 and a remainder of 473.
Use 9 as the next digit of our solution. 
Result so far: 82994.7469879
Deduct 8217 from 8690 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 16:
913 goes into 4730 5 times with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 82994.74698795
Subtracting 4565 from 4730 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 82994.74698795 with a remainder of 1.65e-07.
