We're dividing 20178054 by 45 
We're looking to find how many times 45 goes into 20178054.

Step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 45

Going ahead to step 2:
When dividing 20 by 45, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 45

Moving on to step 3:
When dividing 201 by 45, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 21 after subtracting 180 from 201.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 45

Advancing to step 4:
45 can be fit into 217 4 times, resulting in a remainder of 37.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 180 from 217 and we're left with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 45

Advancing to step 5:
The number 45 fits into 378 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 448.0
Subtracting 360 from 378 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 45

On to step 6:
45 can be fit into 180 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4484.0
If we take 180 away from 180, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 45

Going ahead to step 7:
When dividing 5 by 45, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 44840.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 45

Let's proceed to step 8:
45 can be fit into 54 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 448401.0
Deduct 45 from 54 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 45 fits into 90 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 448401.2
Subtracting 90 from 90 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.

Step 10:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 448401.2
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.

Going ahead to step 11:
When dividing 0 by 45, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 448401.2
Deduct 0 from 0 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.

The quotient of the division is 448401.2, and the remainder is 0.0.
