20655858 ÷ 45 
We're looking to find how many times 45 goes into 20655858.

On to step 1:
45 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

On to step 2:
When dividing 20 by 45, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 45

Going ahead to step 3:
The number 45 fits into 206 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 180 from 206 to get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 45

Moving on to step 4:
45 goes into 265 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 225 from 265 and we're left with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 45

On to step 5:
45 goes into 405 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Deduct 405 from 405 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 45

Advancing to step 6:
8 divided by 45 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 4590.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 45

On to step 7:
If we divide 85 by 45, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 45901.0
If we take 45 away from 85, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 45

Let's proceed to step 8:
If we divide 408 by 45, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 459019.0
The remainder is 3 after subtracting 405 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 45 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 459019.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On 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: 459019.06
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 459019.066
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.

Our division results in 459019.066 with a remaining 0.003.
