On to step 4:
109 goes into 975 8 times with a remainder of 103.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 872 from 975 and we're left with 103.
Append the next digit (5) from the dividend to 103 and continue with: 1035 / 109

Moving on to step 5:
If we divide 1035 by 109, we get 9 and a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 689.0
Subtract 981 from 1035 to get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 109

On to step 6:
549 divided by 109 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 6895.0
The remainder is 4 after subtracting 545 from 549.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 109

Let's proceed to step 7:
When dividing 48 by 109, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 68950.0
Subtract 0 from 48 to get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 109

Step 8:
489 divided by 109 is 4 with a remainder of 53.
The next digit of our result is 4. 
Result so far: 689504.0
Deduct 436 from 489 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
109 can be fit into 530 4 times, resulting in a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 689504.4
Subtract 436 from 530 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
109 goes into 940 8 times with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 689504.48
Deduct 872 from 940 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
When dividing 680 by 109, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 689504.486
Subtract 654 from 680 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 109 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 689504.4862
If we subtract 218 from 260, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
If we divide 420 by 109, we get 3 and a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 689504.48623
Subtract 327 from 420 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 14:
109 goes into 930 8 times with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 689504.486238
If we subtract 872 from 930, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 15:
The number 109 fits into 580 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 689504.4862385
If we take 545 away from 580, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 16:
If we divide 350 by 109, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 689504.48623853
The remainder is 23 after subtracting 327 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 689504.48623853, with a leftover of 2.3e-08.
