We're dividing 189537 by 45 
Our goal is to divide 189537 by 45.

Advancing to step 1:
1 divided by 45 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 45

Going ahead to step 2:
45 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 45

Moving on to step 3:
189 divided by 45 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 180 from 189 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 45

Let's proceed to step 4:
When dividing 95 by 45, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 5 after subtracting 90 from 95.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 45

On to step 5:
The number 45 fits into 53 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 421.0
Deduct 45 from 53 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 45

Going ahead to step 6:
87 divided by 45 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 4211.0
The remainder is 42 after subtracting 45 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 45 fits into 420 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 4211.9
Deduct 405 from 420 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:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 4211.93
Subtracting 135 from 150 leaves us 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.

Going ahead to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 4211.933
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 quotient of the division is 4211.933, and the remainder is 0.0015.
