65415481 ÷ 45 
We want to figure out the number of times 65415481 can be divided by 45.

Advancing to step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 45

Let's proceed to step 2:
The number 45 fits into 65 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 65 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 45

Advancing to step 3:
45 goes into 204 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 180 from 204 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 45

Let's proceed to step 4:
241 divided by 45 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 145.0
The remainder is 16 after subtracting 225 from 241.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 45

Let's proceed to step 5:
The number 45 fits into 165 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1453.0
If we take 135 away from 165, we end up with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 45

Step 6:
The number 45 fits into 304 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 14536.0
If we take 270 away from 304, we end up with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 45

On to step 7:
If we divide 348 by 45, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 145367.0
Deduct 315 from 348 and we're left with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 45

Moving on to step 8:
The number 45 fits into 331 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 1453677.0
Deduct 315 from 331 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
When dividing 160 by 45, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 1453677.3
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1453677.35
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
45 goes into 250 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1453677.355
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 1453677.355, with a leftover of 0.0025.
