We divide 85489865 by 45
We want to figure out the number of times 85489865 can be divided by 45.

On to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 45

Let's proceed to step 2:
85 divided by 45 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 85 leaves us with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 45

Advancing to step 3:
If we divide 404 by 45, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 360 from 404 leaves us with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 45

Let's proceed to step 4:
45 goes into 448 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 189.0
The remainder is 43 after subtracting 405 from 448.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 45

Step 5:
439 divided by 45 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 1899.0
Deduct 405 from 439 and we're left with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 45

Going ahead to step 6:
45 goes into 348 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 18997.0
Subtracting 315 from 348 leaves us with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 45

Let's proceed to step 7:
45 can be fit into 336 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 189977.0
If we take 315 away from 336, we end up with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 45

On to step 8:
When dividing 215 by 45, we get 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 1899774.0
The remainder is 35 after subtracting 180 from 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 45 is 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 1899774.7
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
If we divide 350 by 45, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1899774.77
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 1899774.77, with a leftover of 0.035.
