979872 divided by 45 
We're looking to find how many times 45 goes into 979872.

On to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 45

Going ahead to step 2:
97 divided by 45 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 90 from 97 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 45

Let's proceed to step 3:
The number 45 fits into 79 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 45 from 79 leaves us with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 45

Moving on to step 4:
The number 45 fits into 348 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
Subtracting 315 from 348 leaves us with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 45

Moving on to step 5:
45 goes into 337 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 2177.0
If we take 315 away from 337, we end up with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 45

Moving on to step 6:
45 can be fit into 222 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 21774.0
Subtracting 180 from 222 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
When dividing 420 by 45, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 21774.9
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 21774.93
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 45 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 21774.933
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 21774.933 and a remainder of 0.0015.
