If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 537

Step 2:
If we divide 15 by 537, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 537

Step 3:
155 divided by 537 is 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Grab the next digit (1) from the dividend, add it to 155, then carry on: 1551 / 537

Step 4:
If we divide 1551 by 537, we get 2 and a remainder of 477.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1074 from 1551 to get 477.
Bring next digit (6) of the dividend behind the 477 and repeat the process: 4776 / 537

Advancing to step 5:
4776 divided by 537 is 8 with a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 4296 from 4776, we get 480.
Bring next digit (4) of the dividend behind the 480 and repeat the process: 4804 / 537

Advancing to step 6:
The number 537 fits into 4804 8 times, leaving a remainder of 508.
The next digit of our result is 8. 
Result so far: 288.0
Subtract 4296 from 4804 to get 508.
Grab the next digit (3) from the dividend, add it to 508, then carry on: 5083 / 537

Going ahead to step 7:
The number 537 fits into 5083 9 times, leaving a remainder of 250.
Put 9 as the next digit of the answer. 
Result so far: 2889.0
Deduct 4833 from 5083 and we're left with 250.
Grab the next digit (7) from the dividend, add it to 250, then carry on: 2507 / 537

Moving on to step 8:
2507 divided by 537 is 4 with a remainder of 359.
Record the quotient 4 as the next digit in the result. 
Result so far: 28894.0
If we subtract 2148 from 2507, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
537 goes into 3590 6 times with a remainder of 368.
Put 6 as the next digit of the answer. 
Result so far: 28894.6
Deduct 3222 from 3590 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 10:
If we divide 3680 by 537, we get 6 and a remainder of 458.
Write down 6 as next digit of the result. 
Result so far: 28894.66
If we subtract 3222 from 3680, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The quotient of the division is 28894.66, and the remainder is 0.458.
