Advancing to step 8:
397 can be fit into 3591 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 228919.0
If we take 3573 away from 3591, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 397, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 228919.0
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
The number 397 fits into 1800 4 times, leaving a remainder of 212.
Put 4 as the next digit of the answer. 
Result so far: 228919.04
Deduct 1588 from 1800 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
If we divide 2120 by 397, we get 5 and a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 228919.045
Deduct 1985 from 2120 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 12:
397 goes into 1350 3 times with a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 228919.0453
If we take 1191 away from 1350, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 13:
The number 397 fits into 1590 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 228919.04534
If we subtract 1588 from 1590, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
When dividing 20 by 397, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 228919.04534
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
The number 397 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 228919.04534
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 228919.04534 with a remaining 2e-06.
