We're dividing 730639 by 90 
Our goal is to divide 730639 by 90.

Advancing to step 1:
90 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 90

On to step 2:
90 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 90

Step 3:
90 can be fit into 730 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 720 from 730 leaves us with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 90

Let's proceed to step 4:
If we divide 106 by 90, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 16 after subtracting 90 from 106.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 90

Step 5:
163 divided by 90 is 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 811.0
Subtracting 90 from 163 leaves us with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 90

Moving on to step 6:
The number 90 fits into 739 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 8118.0
Subtracting 720 from 739 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 90, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 8118.2
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 8118.21
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 8118.211
Deduct 90 from 100 and we're left 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 8118.211 with a balance of 0.001.
