We divide 53902 by 45
Our goal is to divide 53902 by 45.

Moving on to step 1:
45 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 45

Step 2:
When dividing 53 by 45, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 53 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 45

Going ahead to step 3:
When dividing 89 by 45, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 45 from 89 and we're left with 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 45

Let's proceed to step 4:
440 divided by 45 is 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 119.0
Subtract 405 from 440 to get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 45

On to step 5:
The number 45 fits into 352 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 1197.0
Deduct 315 from 352 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 6:
The number 45 fits into 370 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 1197.8
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 45, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 1197.82
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 45 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1197.822
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1197.822 with a remaining 0.001.
