On to step 10:
When dividing 430 by 63, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 1077983.96
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
63 can be fit into 520 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1077983.968
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 63 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1077983.9682
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
63 goes into 340 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1077983.96825
Deduct 315 from 340 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
250 divided by 63 is 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 1077983.968253
Subtract 189 from 250 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 15:
