On to step 5:
526 can be fit into 4880 9 times, resulting in a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Subtract 4734 from 4880 to get 146.
Fetch the next digit (5) from the dividend, attach it to 146 and continue: 1465 / 526

Moving on to step 6:
526 can be fit into 1465 2 times, resulting in a remainder of 413.
The next digit of our result is 2. 
Result so far: 1492.0
If we subtract 1052 from 1465, we get 413.
Bring next digit (0) of the dividend behind the 413 and repeat the process: 4130 / 526

Advancing to step 7:
The number 526 fits into 4130 7 times, leaving a remainder of 448.
Record the quotient 7 as the next digit in the result. 
Result so far: 14927.0
If we take 3682 away from 4130, we end up with 448.
Bring next digit (6) of the dividend behind the 448 and repeat the process: 4486 / 526

Let's proceed to step 8:
When dividing 4486 by 526, we get 8 with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 149278.0
Subtract 4208 from 4486 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 9:
If we divide 2780 by 526, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 149278.5
Subtract 2630 from 2780 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
If we divide 1500 by 526, we get 2 and a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 149278.52
Deduct 1052 from 1500 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 11:
The number 526 fits into 4480 8 times, leaving a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 149278.528
The remainder is 272 after subtracting 4208 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
The number 526 fits into 2720 5 times, leaving a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 149278.5285
If we take 2630 away from 2720, we end up 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 13:
526 goes into 900 1 times with a remainder of 374.
The next digit of our result is 1. 
Result so far: 149278.52851
Subtracting 526 from 900 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 14:
526 can be fit into 3740 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 149278.528517
If we take 3682 away from 3740, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
526 goes into 580 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 149278.5285171
Subtract 526 from 580 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 16:
The number 526 fits into 540 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 149278.52851711
Subtracting 526 from 540 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 149278.52851711 and a remainder of 1.4e-08.
