We look at the division of 169853 by 45 
Our goal is to divide 169853 by 45.

Going ahead to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 45

Let's proceed to step 2:
The number 45 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 45

Let's proceed to step 3:
If we divide 169 by 45, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 135 from 169 to get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 45

Going ahead to step 4:
The number 45 fits into 348 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 315 from 348 and we're left with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 45

Let's proceed to step 5:
When dividing 335 by 45, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 377.0
Subtracting 315 from 335 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 45

Moving on to step 6:
45 goes into 203 4 times with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 3774.0
Deduct 180 from 203 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
45 can be fit into 230 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3774.5
Subtracting 225 from 230 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 3774.51
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
50 divided by 45 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 3774.511
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 3774.511 with a remaining 0.0005.
