We look at the division of 56127253 by 645 
Let's see how many times 645 fits into 56127253.

Going ahead to step 1:
The number 645 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 645

Moving on to step 2:
56 divided by 645 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 645

Step 3:
The number 645 fits into 561 0 times, leaving a remainder of 561.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 561 after subtracting 0 from 561.
Grab the next digit (2) from the dividend, add it to 561, then carry on: 5612 / 645

Moving on to step 4:
645 can be fit into 5612 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5160 away from 5612, we end up with 452.
Grab the next digit (7) from the dividend, add it to 452, then carry on: 4527 / 645

Let's proceed to step 5:
4527 divided by 645 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 12 after subtracting 4515 from 4527.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 645

Moving on to step 6:
When dividing 122 by 645, we get 0 with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
If we subtract 0 from 122, we get 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 645

Going ahead to step 7:
If we divide 1225 by 645, we get 1 and a remainder of 580.
The number 1 becomes the next digit in our result. 
Result so far: 8701.0
Deduct 645 from 1225 and we're left with 580.
Fetch the next digit (3) from the dividend, attach it to 580 and continue: 5803 / 645

Going ahead to step 8:
The number 645 fits into 5803 8 times, leaving a remainder of 643.
Record the quotient 8 as the next digit in the result. 
Result so far: 87018.0
Subtract 5160 from 5803 to get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 9:
645 can be fit into 6430 9 times, resulting in a remainder of 625.
Record the quotient 9 as the next digit in the result. 
Result so far: 87018.9
The remainder is 625 after subtracting 5805 from 6430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 10:
If we divide 6250 by 645, we get 9 and a remainder of 445.
Write down 9 as next digit of the result. 
Result so far: 87018.99
If we subtract 5805 from 6250, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final result is 87018.99 with a remainder of 0.445.
