84507259 divided by 654 
Our goal is to divide 84507259 by 654.

Step 1:
If we divide 8 by 654, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 654

Moving on to step 2:
654 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 654

Let's proceed to step 3:
654 can be fit into 845 1 times, resulting in a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 654 away from 845, we end up with 191.
Fetch the next digit (0) from the dividend, attach it to 191 and continue: 1910 / 654

Step 4:
654 goes into 1910 2 times with a remainder of 602.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1308 from 1910 to get 602.
Include the next digit (7) from the dividend after 602, then repeat: 6027 / 654

Let's proceed to step 5:
654 goes into 6027 9 times with a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 5886 from 6027, we get 141.
Bring next digit (2) of the dividend behind the 141 and repeat the process: 1412 / 654

Moving on to step 6:
The number 654 fits into 1412 2 times, leaving a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.0
Subtract 1308 from 1412 to get 104.
Include the next digit (5) from the dividend after 104, then repeat: 1045 / 654

Going ahead to step 7:
654 can be fit into 1045 1 times, resulting in a remainder of 391.
Use 1 as the next digit of our solution. 
Result so far: 12921.0
If we take 654 away from 1045, we end up with 391.
Fetch the next digit (9) from the dividend, attach it to 391 and continue: 3919 / 654

On to step 8:
When dividing 3919 by 654, we get 5 with a remainder of 649.
The next digit of our result is 5. 
Result so far: 129215.0
The remainder is 649 after subtracting 3270 from 3919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

On to step 9:
654 goes into 6490 9 times with a remainder of 604.
Record the quotient 9 as the next digit in the result. 
Result so far: 129215.9
If we subtract 5886 from 6490, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 10:
654 goes into 6040 9 times with a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 129215.99
Subtracting 5886 from 6040 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 129215.99, with a leftover of 0.154.
