Let's divide 645521 by 89
We want to figure out the number of times 645521 can be divided by 89.

On to step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 89

Let's proceed to step 2:
When dividing 64 by 89, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 89

On to step 3:
89 can be fit into 645 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 623 from 645, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 89

On to step 4:
89 can be fit into 225 2 times, resulting in a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 178 from 225 to get 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 89

Step 5:
89 goes into 472 5 times with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
Deduct 445 from 472 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 89

Step 6:
89 goes into 271 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7253.0
If we take 267 away from 271, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 89 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7253.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 89 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 7253.04
Subtracting 356 from 400 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
440 divided by 89 is 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 7253.044
If we subtract 356 from 440, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 7253.044 with a balance of 0.0084.
