Let's divide 87603509 by 561
We want to figure out the number of times 87603509 can be divided by 561.

Moving on to step 1:
8 divided by 561 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 561

Let's proceed to step 2:
The number 561 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 561

On to step 3:
If we divide 876 by 561, we get 1 and a remainder of 315.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 561 away from 876, we end up with 315.
Bring next digit (0) of the dividend behind the 315 and repeat the process: 3150 / 561

On to step 4:
3150 divided by 561 is 5 with a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2805 away from 3150, we end up with 345.
Grab the next digit (3) from the dividend, add it to 345, then carry on: 3453 / 561

Going ahead to step 5:
When dividing 3453 by 561, we get 6 with a remainder of 87.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Subtract 3366 from 3453 to get 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 561

Let's proceed to step 6:
When dividing 875 by 561, we get 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1561.0
Deduct 561 from 875 and we're left with 314.
Take the next digit (0) from the dividend and append it to 314, then repeat: 3140 / 561

Step 7:
3140 divided by 561 is 5 with a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 15615.0
Subtract 2805 from 3140 to get 335.
Grab the next digit (9) from the dividend, add it to 335, then carry on: 3359 / 561

Going ahead to step 8:
If we divide 3359 by 561, we get 5 and a remainder of 554.
Record the quotient 5 as the next digit in the result. 
Result so far: 156155.0
If we take 2805 away from 3359, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 9:
If we divide 5540 by 561, we get 9 and a remainder of 491.
Write down 9 as next digit of the result. 
Result so far: 156155.9
The remainder is 491 after subtracting 5049 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 10:
561 goes into 4910 8 times with a remainder of 422.
Record the quotient 8 as the next digit in the result. 
Result so far: 156155.98
Subtracting 4488 from 4910 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 11:
The number 561 fits into 4220 7 times, leaving a remainder of 293.
The next digit of our result is 7. 
Result so far: 156155.987
Subtract 3927 from 4220 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 12:
If we divide 2930 by 561, we get 5 and a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 156155.9875
Subtracting 2805 from 2930 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 13:
1250 divided by 561 is 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 156155.98752
The remainder is 128 after subtracting 1122 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
The number 561 fits into 1280 2 times, leaving a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 156155.987522
If we take 1122 away from 1280, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

In conclusion, the division gives 156155.987522 with a balance of 1.58e-05.
