Advancing to step 2:
The number 658 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 658

Going ahead to step 3:
When dividing 533 by 658, we get 0 with a remainder of 533.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 533, we get 533.
Append the next digit (0) from the dividend to 533 and continue with: 5330 / 658

On to step 4:
658 goes into 5330 8 times with a remainder of 66.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5264 away from 5330, we end up with 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 658

Moving on to step 5:
When dividing 669 by 658, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 658 from 669 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 658

Going ahead to step 6:
The number 658 fits into 118 0 times, leaving a remainder of 118.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
Subtracting 0 from 118 leaves us with 118.
Append the next digit (0) from the dividend to 118 and continue with: 1180 / 658

On to step 7:
When dividing 1180 by 658, we get 1 with a remainder of 522.
The next digit of our result is 1. 
Result so far: 8101.0
The remainder is 522 after subtracting 658 from 1180.
Bring next digit (1) of the dividend behind the 522 and repeat the process: 5221 / 658

Moving on to step 8:
658 goes into 5221 7 times with a remainder of 615.
Record the quotient 7 as the next digit in the result. 
Result so far: 81017.0
If we subtract 4606 from 5221, we get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 9:
When dividing 6150 by 658, we get 9 with a remainder of 228.
Put 9 as the next digit of the answer. 
Result so far: 81017.9
Deduct 5922 from 6150 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
The number 658 fits into 2280 3 times, leaving a remainder of 306.
The number 3 becomes the next digit in our result. 
Result so far: 81017.93
Subtract 1974 from 2280 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 11:
658 can be fit into 3060 4 times, resulting in a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 81017.934
The remainder is 428 after subtracting 2632 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 12:
4280 divided by 658 is 6 with a remainder of 332.
Use 6 as the next digit of our solution. 
Result so far: 81017.9346
Deduct 3948 from 4280 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 13:
When dividing 3320 by 658, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 81017.93465
If we take 3290 away from 3320, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
300 divided by 658 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 81017.93465
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 15:
658 goes into 3000 4 times with a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 81017.9346504
If we subtract 2632 from 3000, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 16:
658 goes into 3680 5 times with a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 81017.93465045
If we subtract 3290 from 3680, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 81017.93465045 with a remainder of 3.9e-07.
