13504759 divided by 87 
We want to figure out the number of times 13504759 can be divided by 87.

Going ahead to step 1:
1 divided by 87 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 87

On to step 2:
When dividing 13 by 87, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 87

Let's proceed to step 3:
87 goes into 135 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 135, we end up with 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 87

On to step 4:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 435 away from 480, we end up with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 87

Step 5:
87 goes into 454 5 times with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
If we subtract 435 from 454, we get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 87

Advancing to step 6:
If we divide 197 by 87, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 1552.0
Subtract 174 from 197 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 87

On to step 7:
87 goes into 235 2 times with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 15522.0
If we take 174 away from 235, we end up with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 87

Moving on to step 8:
When dividing 619 by 87, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 155227.0
The remainder is 10 after subtracting 609 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 87 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 155227.1
Subtract 87 from 100 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
The number 87 fits into 130 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 155227.11
Subtracting 87 from 130 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 155227.11 and a remainder of 0.043.
