Let's divide 55348418 by 645
Let's see how many times 645 fits into 55348418.

Going ahead to step 1:
645 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 645

Step 2:
When dividing 55 by 645, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 645

Step 3:
553 divided by 645 is 0 with a remainder of 553.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 553, we end up with 553.
Bring next digit (4) of the dividend behind the 553 and repeat the process: 5534 / 645

Let's proceed to step 4:
The number 645 fits into 5534 8 times, leaving a remainder of 374.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5160 from 5534 and we're left with 374.
Bring next digit (8) of the dividend behind the 374 and repeat the process: 3748 / 645

Step 5:
If we divide 3748 by 645, we get 5 and a remainder of 523.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 3225 from 3748 and we're left with 523.
Append the next digit (4) from the dividend to 523 and continue with: 5234 / 645

Step 6:
645 can be fit into 5234 8 times, resulting in a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
The remainder is 74 after subtracting 5160 from 5234.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 645

Going ahead to step 7:
The number 645 fits into 741 1 times, leaving a remainder of 96.
The next digit of our result is 1. 
Result so far: 8581.0
If we subtract 645 from 741, we get 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 645

Moving on to step 8:
645 can be fit into 968 1 times, resulting in a remainder of 323.
Use 1 as the next digit of our solution. 
Result so far: 85811.0
If we subtract 645 from 968, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 9:
645 can be fit into 3230 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 85811.5
Subtract 3225 from 3230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
50 divided by 645 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 85811.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
The number 645 fits into 500 0 times, leaving a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 85811.5
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 85811.5 with a balance of 0.05.
