We look at the division of 864441 by 89 
We want to figure out the number of times 864441 can be divided by 89.

Advancing to step 1:
When dividing 8 by 89, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 89

Advancing to step 2:
If we divide 86 by 89, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 89

On to step 3:
If we divide 864 by 89, we get 9 and a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 801 away from 864, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 89

Going ahead to step 4:
634 divided by 89 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 623 from 634 and we're left with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 89

Moving on to step 5:
When dividing 114 by 89, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 971.0
Subtract 89 from 114 to get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 89

Moving on to step 6:
89 can be fit into 251 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 9712.0
Subtracting 178 from 251 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
If we divide 730 by 89, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 9712.8
Subtracting 712 from 730 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
89 goes into 180 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 9712.82
If we take 178 away from 180, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 89 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9712.82
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 89, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 9712.8202
If we take 178 away from 200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
220 divided by 89 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 9712.82022
Deduct 178 from 220 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 9712.82022, with a leftover of 4.2e-05.
