Let's divide 86904599 by 655
We want to figure out the number of times 86904599 can be divided by 655.

On to step 1:
If we divide 8 by 655, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 655

Going ahead to step 2:
When dividing 86 by 655, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 655

On to step 3:
The number 655 fits into 869 1 times, leaving a remainder of 214.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 655 away from 869, we end up with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 655

Step 4:
2140 divided by 655 is 3 with a remainder of 175.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1965 from 2140 leaves us with 175.
Include the next digit (4) from the dividend after 175, then repeat: 1754 / 655

Advancing to step 5:
655 goes into 1754 2 times with a remainder of 444.
Write down 2 as next digit of the result. 
Result so far: 132.0
The remainder is 444 after subtracting 1310 from 1754.
Fetch the next digit (5) from the dividend, attach it to 444 and continue: 4445 / 655

On to step 6:
The number 655 fits into 4445 6 times, leaving a remainder of 515.
The next digit of our result is 6. 
Result so far: 1326.0
Deduct 3930 from 4445 and we're left with 515.
Bring next digit (9) of the dividend behind the 515 and repeat the process: 5159 / 655

Step 7:
655 can be fit into 5159 7 times, resulting in a remainder of 574.
The next digit of our result is 7. 
Result so far: 13267.0
Subtract 4585 from 5159 to get 574.
Fetch the next digit (9) from the dividend, attach it to 574 and continue: 5749 / 655

Advancing to step 8:
655 can be fit into 5749 8 times, resulting in a remainder of 509.
The next digit of our result is 8. 
Result so far: 132678.0
Subtract 5240 from 5749 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 9:
When dividing 5090 by 655, we get 7 with a remainder of 505.
The next digit of our result is 7. 
Result so far: 132678.7
If we take 4585 away from 5090, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 10:
655 goes into 5050 7 times with a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 132678.77
Deduct 4585 from 5050 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

The final outcome is 132678.77, with a leftover of 0.465.
