We're dividing 53481481 by 45 
Our goal is to divide 53481481 by 45.

On to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 45

Moving on to step 2:
The number 45 fits into 53 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 53, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 45

Let's proceed to step 3:
If we divide 84 by 45, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 45 from 84, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 45

Let's proceed to step 4:
45 can be fit into 398 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtracting 360 from 398 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 45

Advancing to step 5:
If we divide 381 by 45, we get 8 and a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 1188.0
The remainder is 21 after subtracting 360 from 381.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 45

On to step 6:
The number 45 fits into 214 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 11884.0
Deduct 180 from 214 and we're left with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 45

Let's proceed to step 7:
If we divide 348 by 45, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 118847.0
Subtracting 315 from 348 leaves us with 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 45

Let's proceed to step 8:
331 divided by 45 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 1188477.0
Subtracting 315 from 331 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
45 can be fit into 160 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1188477.3
If we take 135 away from 160, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
When dividing 250 by 45, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1188477.35
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
250 divided by 45 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1188477.355
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 1188477.355, and the remainder is 0.0025.
