Let's divide 386691 by 45
Our goal is to divide 386691 by 45.

Step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 45

Going ahead to step 2:
45 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 45

Let's proceed to step 3:
45 can be fit into 386 8 times, resulting in a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 360 from 386, we get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 45

Going ahead to step 4:
266 divided by 45 is 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 85.0
Subtract 225 from 266 to get 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 45

Let's proceed to step 5:
45 can be fit into 419 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Subtracting 405 from 419 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 45

Advancing to step 6:
The number 45 fits into 141 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 8593.0
Subtracting 135 from 141 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
45 can be fit into 60 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 8593.1
If we take 45 away from 60, 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.

On to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 8593.13
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.

Moving on to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 8593.133
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.

In conclusion, the division gives 8593.133 with a balance of 0.0015.
