Advancing to step 11:
3470 divided by 637 is 5 with a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 49588.695
Subtracting 3185 from 3470 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 12:
2850 divided by 637 is 4 with a remainder of 302.
Write down 4 as next digit of the result. 
Result so far: 49588.6954
Deduct 2548 from 2850 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 13:
The number 637 fits into 3020 4 times, leaving a remainder of 472.
Record the quotient 4 as the next digit in the result. 
Result so far: 49588.69544
Subtract 2548 from 3020 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

In conclusion, the division gives 49588.69544 with a balance of 0.000472.
