Going ahead to step 4:
The number 726 fits into 6659 9 times, leaving a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 6534 away from 6659, we end up with 125.
Bring next digit (0) of the dividend behind the 125 and repeat the process: 1250 / 726

Step 5:
When dividing 1250 by 726, we get 1 with a remainder of 524.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 726 from 1250 leaves us with 524.
Bring next digit (2) of the dividend behind the 524 and repeat the process: 5242 / 726

Let's proceed to step 6:
5242 divided by 726 is 7 with a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 917.0
If we subtract 5082 from 5242, we get 160.
Append the next digit (1) from the dividend to 160 and continue with: 1601 / 726

On to step 7:
The number 726 fits into 1601 2 times, leaving a remainder of 149.
The next digit of our result is 2. 
Result so far: 9172.0
If we subtract 1452 from 1601, we get 149.
Fetch the next digit (4) from the dividend, attach it to 149 and continue: 1494 / 726

Advancing to step 8:
726 can be fit into 1494 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 91722.0
Subtracting 1452 from 1494 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
The number 726 fits into 420 0 times, leaving a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 91722.0
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
4200 divided by 726 is 5 with a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 91722.05
Subtract 3630 from 4200 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 11:
5700 divided by 726 is 7 with a remainder of 618.
The next digit of our result is 7. 
Result so far: 91722.057
If we take 5082 away from 5700, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 12:
The number 726 fits into 6180 8 times, leaving a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 91722.0578
If we subtract 5808 from 6180, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 13:
726 can be fit into 3720 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 91722.05785
Deduct 3630 from 3720 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
If we divide 900 by 726, we get 1 and a remainder of 174.
The next digit of our result is 1. 
Result so far: 91722.057851
The remainder is 174 after subtracting 726 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 15:
726 goes into 1740 2 times with a remainder of 288.
The next digit of our result is 2. 
Result so far: 91722.0578512
Subtracting 1452 from 1740 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 16:
2880 divided by 726 is 3 with a remainder of 702.
Record the quotient 3 as the next digit in the result. 
Result so far: 91722.05785123
If we subtract 2178 from 2880, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

In conclusion, the division gives 91722.05785123 with a balance of 7.02e-07.
