We look at the division of 136409 by 87 
Let's see how many times 87 fits into 136409.

Advancing to step 1:
If we divide 1 by 87, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

On to step 2:
When dividing 13 by 87, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 87

On to step 3:
136 divided by 87 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 87 from 136 to get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 87

Moving on to step 4:
87 goes into 494 5 times with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 435 from 494 leaves us with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 87

Moving on to step 5:
87 goes into 590 6 times with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 522 from 590 leaves us with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 87

Going ahead to step 6:
The number 87 fits into 689 7 times, leaving a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 1567.0
If we take 609 away from 689, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
If we divide 800 by 87, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 1567.9
If we take 783 away from 800, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
The number 87 fits into 170 1 times, leaving a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 1567.91
If we subtract 87 from 170, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
87 can be fit into 830 9 times, resulting in a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 1567.919
If we take 783 away from 830, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
470 divided by 87 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1567.9195
Deduct 435 from 470 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
If we divide 350 by 87, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 1567.91954
If we take 348 away from 350, 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.

Advancing to step 12:
The number 87 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1567.91954
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
87 goes into 200 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 1567.9195402
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 87 fits into 260 2 times, leaving a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 1567.91954022
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 1567.91954022 and a remainder of 8.6e-08.
