Let's divide 973011 by 90
We want to figure out the number of times 973011 can be divided by 90.

Going ahead to step 1:
90 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 90

On to step 2:
90 goes into 97 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 90 from 97 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 90

Going ahead to step 3:
When dividing 73 by 90, we get 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 90

Going ahead to step 4:
If we divide 730 by 90, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtract 720 from 730 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 90

Step 5:
101 divided by 90 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1081.0
Subtracting 90 from 101 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 90

Step 6:
90 can be fit into 111 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 10811.0
Deduct 90 from 111 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 90 fits into 210 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 10811.2
Subtracting 180 from 210 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 10811.23
Subtract 270 from 300 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 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 10811.233
Deduct 270 from 300 and we're left with 30.
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 10811.233 and a remainder of 0.003.
