We're dividing 63430030 by 90 
We're looking to find how many times 90 goes into 63430030.

Advancing to step 1:
When dividing 6 by 90, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 90

Going ahead to step 2:
When dividing 63 by 90, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 90

Moving on to step 3:
If we divide 634 by 90, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 630 from 634 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 90

Step 4:
If we divide 43 by 90, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 43, we end up with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 90

Moving on to step 5:
90 can be fit into 430 4 times, resulting in a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 704.0
Deduct 360 from 430 and we're left with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 90

Moving on to step 6:
If we divide 700 by 90, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 7047.0
Subtract 630 from 700 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 90

Let's proceed to step 7:
If we divide 703 by 90, we get 7 and a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 70477.0
If we take 630 away from 703, we end up with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 90

On to step 8:
730 divided by 90 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 704778.0
Subtracting 720 from 730 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 704778.1
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 90, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 704778.11
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 704778.11 with a balance of 0.01.
