1054815 ÷ 45 
We want to divide 1054815 by 45.

On to step 1:
1 divided by 45 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 45

Advancing to step 2:
If we divide 10 by 45, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 45

Going ahead to step 3:
When dividing 105 by 45, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 90 from 105 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 45

Step 4:
The number 45 fits into 154 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 19 after subtracting 135 from 154.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 45

Moving on to step 5:
When dividing 198 by 45, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 234.0
If we take 180 away from 198, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 45

Advancing to step 6:
The number 45 fits into 181 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2344.0
Deduct 180 from 181 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 45

Moving on to step 7:
45 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 23440.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 23440.3
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 23440.33
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 23440.33, with a leftover of 0.015.
