If we divide 6079 by 913, we get 6 and a remainder of 601.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we take 5478 away from 6079, we end up with 601.
Append the next digit (4) from the dividend to 601 and continue with: 6014 / 913

On to step 7:
913 goes into 6014 6 times with a remainder of 536.
The next digit of our result is 6. 
Result so far: 4366.0
Subtract 5478 from 6014 to get 536.
Take the next digit (4) from the dividend and append it to 536, then repeat: 5364 / 913

Let's proceed to step 8:
The number 913 fits into 5364 5 times, leaving a remainder of 799.
Use 5 as the next digit of our solution. 
Result so far: 43665.0
Subtract 4565 from 5364 to get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Step 9:
7990 divided by 913 is 8 with a remainder of 686.
Write down 8 as next digit of the result. 
Result so far: 43665.8
If we take 7304 away from 7990, we end up with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 10:
913 goes into 6860 7 times with a remainder of 469.
Put 7 as the next digit of the answer. 
Result so far: 43665.87
The remainder is 469 after subtracting 6391 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

On to step 11:
913 goes into 4690 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 43665.875
Subtract 4565 from 4690 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
The number 913 fits into 1250 1 times, leaving a remainder of 337.
The next digit of our result is 1. 
Result so far: 43665.8751
The remainder is 337 after subtracting 913 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 13:
The number 913 fits into 3370 3 times, leaving a remainder of 631.
Write down 3 as next digit of the result. 
Result so far: 43665.87513
Subtracting 2739 from 3370 leaves us with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Advancing to step 14:
913 goes into 6310 6 times with a remainder of 832.
Put 6 as the next digit of the answer. 
Result so far: 43665.875136
Subtract 5478 from 6310 to get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 15:
The number 913 fits into 8320 9 times, leaving a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 43665.8751369
Subtract 8217 from 8320 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 16:
913 can be fit into 1030 1 times, resulting in a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 43665.87513691
The remainder is 117 after subtracting 913 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The quotient of the division is 43665.87513691, and the remainder is 1.17e-07.
