We look at the division of 87454019 by 45 
Our goal is to divide 87454019 by 45.

Moving on to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 45

Moving on to step 2:
If we divide 87 by 45, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 87 leaves us with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 45

Moving on to step 3:
If we divide 424 by 45, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 405 from 424 to get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 45

Going ahead to step 4:
If we divide 195 by 45, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Subtract 180 from 195 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 45

Going ahead to step 5:
154 divided by 45 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1943.0
If we take 135 away from 154, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 45

On to step 6:
If we divide 190 by 45, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 19434.0
Subtracting 180 from 190 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 45

Let's proceed to step 7:
101 divided by 45 is 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 194342.0
Subtract 90 from 101 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 45

Step 8:
45 goes into 119 2 times with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 1943422.0
Subtract 90 from 119 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
45 goes into 290 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1943422.6
If we take 270 away from 290, we end up 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.

Moving on to step 10:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1943422.64
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.

Step 11:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1943422.644
The remainder is 20 after subtracting 180 from 200.
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 1943422.644, with a leftover of 0.002.
