We're dividing 99895412 by 45 
We want to figure out the number of times 99895412 can be divided by 45.

Going ahead to step 1:
45 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 45

Step 2:
The number 45 fits into 99 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 90 away from 99, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 45

On to step 3:
98 divided by 45 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 90 from 98, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 45

On to step 4:
89 divided by 45 is 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Subtract 45 from 89 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 45

Moving on to step 5:
45 goes into 445 9 times with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 2219.0
Deduct 405 from 445 and we're left with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 45

Advancing to step 6:
The number 45 fits into 404 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 22198.0
Subtract 360 from 404 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 45

Advancing to step 7:
45 can be fit into 441 9 times, resulting in a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 221989.0
If we subtract 405 from 441, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 45

On to step 8:
When dividing 362 by 45, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 2219898.0
The remainder is 2 after subtracting 360 from 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
45 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2219898.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 45, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2219898.04
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
If we divide 200 by 45, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2219898.044
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2219898.044, with a leftover of 0.002.
