The number 105 fits into 402 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 6813.0
The remainder is 87 after subtracting 315 from 402.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 105

Step 7:
When dividing 879 by 105, we get 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 68138.0
Subtract 840 from 879 to get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 105

Advancing to step 8:
105 can be fit into 397 3 times, resulting in a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 681383.0
If we subtract 315 from 397, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
105 can be fit into 820 7 times, resulting in a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 681383.7
The remainder is 85 after subtracting 735 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
850 divided by 105 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 681383.78
Subtract 840 from 850 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 105 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 681383.78
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
105 goes into 1000 9 times with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 681383.7809
Subtract 945 from 1000 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
550 divided by 105 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 681383.78095
Subtract 525 from 550 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
250 divided by 105 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 681383.780952
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
If we divide 400 by 105, we get 3 and a remainder of 85.
The next digit of our result is 3. 
Result so far: 681383.7809523
Deduct 315 from 400 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 16:
When dividing 850 by 105, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 681383.78095238
Subtract 840 from 850 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.
