We divide 99315 by 45
We want to divide 99315 by 45.

On to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 45

Moving on to step 2:
The number 45 fits into 99 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 90 from 99 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 45

Advancing to step 3:
If we divide 93 by 45, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 90 away from 93, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 45

Advancing to step 4:
The number 45 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 45

Moving on to step 5:
45 goes into 315 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2207.0
Deduct 315 from 315 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
When dividing 0 by 45, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2207.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2207.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2207.0 with a remainder of 0.0.
