We're dividing 87680471 by 136 
Our goal is to divide 87680471 by 136.

Let's proceed to step 1:
136 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 136

Advancing to step 2:
When dividing 87 by 136, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 136

Step 3:
The number 136 fits into 876 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 816 from 876 to get 60.
Include the next digit (8) from the dividend after 60, then repeat: 608 / 136

Step 4:
608 divided by 136 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 544 from 608, we get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 136

Going ahead to step 5:
The number 136 fits into 640 4 times, leaving a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 644.0
Subtracting 544 from 640 leaves us with 96.
Grab the next digit (4) from the dividend, add it to 96, then carry on: 964 / 136

Going ahead to step 6:
964 divided by 136 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 6447.0
If we subtract 952 from 964, we get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 136

Moving on to step 7:
If we divide 127 by 136, we get 0 and a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 64470.0
If we take 0 away from 127, we end up with 127.
Fetch the next digit (1) from the dividend, attach it to 127 and continue: 1271 / 136

Moving on to step 8:
If we divide 1271 by 136, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 644709.0
Subtracting 1224 from 1271 leaves us 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.

Going ahead to step 9:
The number 136 fits into 470 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 644709.3
Subtracting 408 from 470 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
When dividing 620 by 136, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 644709.34
If we take 544 away from 620, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 136 is 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 644709.345
Subtracting 680 from 760 leaves us 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.

Moving on to step 12:
136 can be fit into 800 5 times, resulting in a remainder of 120.
The next digit of our result is 5. 
Result so far: 644709.3455
If we take 680 away from 800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 644709.3455, with a leftover of 0.0012.
