Advancing to step 5:
If we divide 630 by 521, we get 1 and a remainder of 109.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 109 after subtracting 521 from 630.
Include the next digit (9) from the dividend after 109, then repeat: 1099 / 521

Step 6:
1099 divided by 521 is 2 with a remainder of 57.
The next digit of our result is 2. 
Result so far: 1212.0
Deduct 1042 from 1099 and we're left with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 521

Step 7:
The number 521 fits into 576 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 12121.0
If we subtract 521 from 576, we get 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 521

Step 8:
557 divided by 521 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 121211.0
Deduct 521 from 557 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
When dividing 360 by 521, we get 0 with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 121211.0
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
When dividing 3600 by 521, we get 6 with a remainder of 474.
The next digit of our result is 6. 
Result so far: 121211.06
The remainder is 474 after subtracting 3126 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 11:
When dividing 4740 by 521, we get 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 121211.069
Subtract 4689 from 4740 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
The number 521 fits into 510 0 times, leaving a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 121211.069
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 13:
If we divide 5100 by 521, we get 9 and a remainder of 411.
Put 9 as the next digit of the answer. 
Result so far: 121211.06909
If we subtract 4689 from 5100, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Step 14:
521 can be fit into 4110 7 times, resulting in a remainder of 463.
Put 7 as the next digit of the answer. 
Result so far: 121211.069097
Subtract 3647 from 4110 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 15:
521 can be fit into 4630 8 times, resulting in a remainder of 462.
Record the quotient 8 as the next digit in the result. 
Result so far: 121211.0690978
If we subtract 4168 from 4630, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 16:
4620 divided by 521 is 8 with a remainder of 452.
Put 8 as the next digit of the answer. 
Result so far: 121211.06909788
Deduct 4168 from 4620 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The quotient of the division is 121211.06909788, and the remainder is 4.52e-07.
