779172 divided by 45 
We want to figure out the number of times 779172 can be divided by 45.

On to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 45

Moving on to step 2:
77 divided by 45 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 32 after subtracting 45 from 77.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 45

Let's proceed to step 3:
45 can be fit into 329 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 315 from 329, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 45

Let's proceed to step 4:
If we divide 141 by 45, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we take 135 away from 141, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 45

Let's proceed to step 5:
If we divide 67 by 45, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1731.0
Subtracting 45 from 67 leaves us with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 45

Step 6:
The number 45 fits into 222 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 17314.0
Subtract 180 from 222 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead 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: 17314.9
Subtracting 405 from 420 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.

Step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17314.93
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17314.933
Deduct 135 from 150 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.

After the division, we end up with 17314.933 and a remainder of 0.0015.
