Let's divide 902180 by 45
We want to divide 902180 by 45.

Let's proceed to step 1:
45 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 45

Moving on to step 2:
The number 45 fits into 90 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 90 from 90.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 45

Step 3:
When dividing 2 by 45, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 45

Step 4:
When dividing 21 by 45, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 45

On to step 5:
When dividing 218 by 45, we get 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 2004.0
Subtract 180 from 218 to get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 45

Going ahead to step 6:
380 divided by 45 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 20048.0
Subtracting 360 from 380 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.

Moving on to step 7:
45 goes into 200 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 20048.4
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.

Going ahead to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 20048.44
Subtract 180 from 200 to get 20.
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 20048.44, with a leftover of 0.02.
