909637 ÷ 45 
We want to divide 909637 by 45.

Step 1:
9 divided by 45 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 45

Step 2:
If we divide 90 by 45, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 90 from 90 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 45

Step 3:
If we divide 9 by 45, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 45

Step 4:
When dividing 96 by 45, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 202.0
The remainder is 6 after subtracting 90 from 96.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 45

Let's proceed to step 5:
The number 45 fits into 63 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 2021.0
If we take 45 away from 63, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 45

Going ahead to step 6:
When dividing 187 by 45, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 20214.0
The remainder is 7 after subtracting 180 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
45 goes into 70 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 20214.1
If we take 45 away from 70, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 20214.15
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 20214.155
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 20214.155, with a leftover of 0.0025.
