Let's divide 64880987 by 561
We're looking to find how many times 561 goes into 64880987.

Going ahead to step 1:
561 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 561

Step 2:
The number 561 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 561

Going ahead to step 3:
648 divided by 561 is 1 with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 561 from 648 and we're left with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 561

Let's proceed to step 4:
878 divided by 561 is 1 with a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 561 from 878 leaves us with 317.
Append the next digit (0) from the dividend to 317 and continue with: 3170 / 561

Moving on to step 5:
3170 divided by 561 is 5 with a remainder of 365.
The next digit of our result is 5. 
Result so far: 115.0
Subtracting 2805 from 3170 leaves us with 365.
Fetch the next digit (9) from the dividend, attach it to 365 and continue: 3659 / 561

Let's proceed to step 6:
561 can be fit into 3659 6 times, resulting in a remainder of 293.
Put 6 as the next digit of the answer. 
Result so far: 1156.0
The remainder is 293 after subtracting 3366 from 3659.
Append the next digit (8) from the dividend to 293 and continue with: 2938 / 561

Moving on to step 7:
If we divide 2938 by 561, we get 5 and a remainder of 133.
The next digit of our result is 5. 
Result so far: 11565.0
The remainder is 133 after subtracting 2805 from 2938.
Include the next digit (7) from the dividend after 133, then repeat: 1337 / 561

Advancing to step 8:
561 goes into 1337 2 times with a remainder of 215.
The next digit of our result is 2. 
Result so far: 115652.0
Subtracting 1122 from 1337 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 9:
561 goes into 2150 3 times with a remainder of 467.
Put 3 as the next digit of the answer. 
Result so far: 115652.3
The remainder is 467 after subtracting 1683 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Let's proceed to step 10:
561 goes into 4670 8 times with a remainder of 182.
The next digit of our result is 8. 
Result so far: 115652.38
If we take 4488 away from 4670, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
561 can be fit into 1820 3 times, resulting in a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 115652.383
Subtracting 1683 from 1820 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 12:
If we divide 1370 by 561, we get 2 and a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 115652.3832
If we take 1122 away from 1370, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 13:
The number 561 fits into 2480 4 times, leaving a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 115652.38324
Subtracting 2244 from 2480 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 14:
If we divide 2360 by 561, we get 4 and a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 115652.383244
Subtracting 2244 from 2360 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 115652.383244 with a remaining 1.16e-05.
