We divide 55231491 by 45
We want to figure out the number of times 55231491 can be divided by 45.

Let's proceed to step 1:
5 divided by 45 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 45

Let's proceed to step 2:
The number 45 fits into 55 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 45 from 55.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 45

Let's proceed to step 3:
45 goes into 102 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 90 from 102 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 45

Going ahead to step 4:
45 can be fit into 123 2 times, resulting in a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 122.0
The remainder is 33 after subtracting 90 from 123.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 45

Moving on to step 5:
45 can be fit into 331 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 1227.0
If we take 315 away from 331, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 45

On to step 6:
164 divided by 45 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 12273.0
Subtracting 135 from 164 leaves us with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 45

Going ahead to step 7:
45 goes into 299 6 times with a remainder of 29.
The next digit of our result is 6. 
Result so far: 122736.0
Subtract 270 from 299 to get 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 45

Let's proceed to step 8:
When dividing 291 by 45, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 1227366.0
If we take 270 away from 291, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
45 can be fit into 210 4 times, resulting in a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 1227366.4
Subtracting 180 from 210 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1227366.46
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 1227366.466
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 1227366.466, and the remainder is 0.003.
