73307803 divided by 90 
We want to divide 73307803 by 90.

Step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 90

Let's proceed to step 2:
73 divided by 90 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 90

Going ahead to step 3:
The number 90 fits into 733 8 times, leaving a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 720 from 733 leaves us with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 90

Let's proceed to step 4:
If we divide 130 by 90, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 90 from 130 leaves us with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 90

Moving on to step 5:
When dividing 407 by 90, we get 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 814.0
Subtract 360 from 407 to get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 90

Moving on to step 6:
When dividing 478 by 90, we get 5 with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 8145.0
Subtract 450 from 478 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 90

On to step 7:
280 divided by 90 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 81453.0
Subtract 270 from 280 to get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 90

Advancing to step 8:
If we divide 103 by 90, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 814531.0
The remainder is 13 after subtracting 90 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
90 goes into 130 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 814531.1
Subtracting 90 from 130 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 814531.14
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 814531.144
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 814531.144 with a balance of 0.004.
