We're dividing 630093 by 90 
Let's see how many times 90 fits into 630093.

Going ahead to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 90

Moving on to step 2:
90 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 90

Step 3:
90 can be fit into 630 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 630 from 630 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 90

Going ahead to step 4:
When dividing 0 by 90, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 90

Going ahead to step 5:
If we divide 9 by 90, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 700.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 90

Step 6:
If we divide 93 by 90, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 7001.0
Subtracting 90 from 93 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 90, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7001.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 7001.03
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
90 goes into 300 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 7001.033
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 7001.033 and a remainder of 0.003.
