89401640 divided by 564 
We want to figure out the number of times 89401640 can be divided by 564.

Step 1:
8 divided by 564 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 564

Moving on to step 2:
The number 564 fits into 89 0 times, leaving a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 564

Let's proceed to step 3:
When dividing 894 by 564, we get 1 with a remainder of 330.
The next digit of our result is 1. 
Result so far: 1.0
If we take 564 away from 894, we end up with 330.
Grab the next digit (0) from the dividend, add it to 330, then carry on: 3300 / 564

Going ahead to step 4:
564 goes into 3300 5 times with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2820 from 3300 leaves us with 480.
Take the next digit (1) from the dividend and append it to 480, then repeat: 4801 / 564

On to step 5:
564 goes into 4801 8 times with a remainder of 289.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 289 after subtracting 4512 from 4801.
Append the next digit (6) from the dividend to 289 and continue with: 2896 / 564

Let's proceed to step 6:
If we divide 2896 by 564, we get 5 and a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 1585.0
Deduct 2820 from 2896 and we're left with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 564

Going ahead to step 7:
When dividing 764 by 564, we get 1 with a remainder of 200.
The next digit of our result is 1. 
Result so far: 15851.0
Subtracting 564 from 764 leaves us with 200.
Bring next digit (0) of the dividend behind the 200 and repeat the process: 2000 / 564

Let's proceed to step 8:
564 can be fit into 2000 3 times, resulting in a remainder of 308.
Record the quotient 3 as the next digit in the result. 
Result so far: 158513.0
Subtract 1692 from 2000 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 9:
If we divide 3080 by 564, we get 5 and a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 158513.5
If we take 2820 away from 3080, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
The number 564 fits into 2600 4 times, leaving a remainder of 344.
The next digit of our result is 4. 
Result so far: 158513.54
Deduct 2256 from 2600 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 11:
The number 564 fits into 3440 6 times, leaving a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 158513.546
The remainder is 56 after subtracting 3384 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
564 goes into 560 0 times with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 158513.546
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
5600 divided by 564 is 9 with a remainder of 524.
Use 9 as the next digit of our solution. 
Result so far: 158513.54609
If we take 5076 away from 5600, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 14:
564 can be fit into 5240 9 times, resulting in a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 158513.546099
If we take 5076 away from 5240, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 158513.546099 and a remainder of 1.64e-05.
