55639 divided by 45 
We're looking to find how many times 45 goes into 55639.

Let's proceed to step 1:
The number 45 fits into 5 0 times, leaving 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.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 45

Going ahead to step 2:
The number 45 fits into 55 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 45 from 55.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 45

Moving on to step 3:
If we divide 106 by 45, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 90 from 106, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 45

Let's proceed to step 4:
The number 45 fits into 163 3 times, leaving a remainder of 28.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 135 from 163 leaves us with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 45

Advancing to step 5:
289 divided by 45 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 1236.0
If we take 270 away from 289, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
When dividing 190 by 45, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1236.4
If we take 180 away from 190, we end up 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.

Advancing to step 7:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1236.42
If we take 90 away from 100, we end up 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.

Going ahead to step 8:
45 goes into 100 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 1236.422
If we subtract 90 from 100, we 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.

Our division results in 1236.422 with a remaining 0.001.
