Let's divide 745809 by 45
Our goal is to divide 745809 by 45.

Moving on to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 45

Moving on to step 2:
74 divided by 45 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 74, we end up with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 45

Step 3:
295 divided by 45 is 6 with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 270 from 295, we get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 45

Going ahead to step 4:
If we divide 258 by 45, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 225 away from 258, we end up with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 45

Let's proceed to step 5:
When dividing 330 by 45, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1657.0
Subtracting 315 from 330 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 45

Step 6:
The number 45 fits into 159 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 16573.0
If we take 135 away from 159, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 45, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 16573.5
Deduct 225 from 240 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.

On to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 16573.53
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.

Advancing to step 9:
150 divided by 45 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 16573.533
The remainder is 15 after subtracting 135 from 150.
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 16573.533, with a leftover of 0.0015.
