Let's divide 56321551 by 45
Let's see how many times 45 fits into 56321551.

Advancing to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 45

Advancing to step 2:
If we divide 56 by 45, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 56 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 45

Moving on to step 3:
When dividing 113 by 45, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 90 from 113, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 45

Moving on to step 4:
When dividing 232 by 45, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 7 after subtracting 225 from 232.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 45

Let's proceed to step 5:
45 goes into 71 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1251.0
Deduct 45 from 71 and we're left with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 45

Moving on to step 6:
45 can be fit into 265 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 12515.0
The remainder is 40 after subtracting 225 from 265.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 45

Let's proceed to step 7:
405 divided by 45 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 125159.0
The remainder is 0 after subtracting 405 from 405.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 45

Going ahead to step 8:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1251590.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 45, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1251590.0
Subtract 0 from 10 to get 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 10:
If we divide 100 by 45, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 1251590.02
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.

On to step 11:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 1251590.022
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1251590.022, and the remainder is 0.001.
