45120385 divided by 45 
We want to divide 45120385 by 45.

On to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 45

On to step 2:
The number 45 fits into 45 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 45 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 45

Advancing to step 3:
45 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 45

On to step 4:
The number 45 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 45

Advancing to step 5:
If we divide 120 by 45, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
Deduct 90 from 120 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 45

Going ahead to step 6:
When dividing 303 by 45, we get 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 10026.0
Subtracting 270 from 303 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 45

Advancing to step 7:
45 goes into 338 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 100267.0
Subtract 315 from 338 to get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 45

Going ahead to step 8:
45 goes into 235 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1002675.0
Subtract 225 from 235 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1002675.2
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 45, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 1002675.22
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 1002675.22, with a leftover of 0.01.
