84464921 ÷ 663 
Let's see how many times 663 fits into 84464921.

Advancing to step 1:
The number 663 fits into 8 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 663

Going ahead to step 2:
When dividing 84 by 663, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 663

Going ahead to step 3:
663 goes into 844 1 times with a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 181 after subtracting 663 from 844.
Include the next digit (6) from the dividend after 181, then repeat: 1816 / 663

On to step 4:
1816 divided by 663 is 2 with a remainder of 490.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1326 away from 1816, we end up with 490.
Include the next digit (4) from the dividend after 490, then repeat: 4904 / 663

Moving on to step 5:
When dividing 4904 by 663, we get 7 with a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Deduct 4641 from 4904 and we're left with 263.
Grab the next digit (9) from the dividend, add it to 263, then carry on: 2639 / 663

Going ahead to step 6:
The number 663 fits into 2639 3 times, leaving a remainder of 650.
The next digit of our result is 3. 
Result so far: 1273.0
Subtracting 1989 from 2639 leaves us with 650.
Fetch the next digit (2) from the dividend, attach it to 650 and continue: 6502 / 663

Going ahead to step 7:
6502 divided by 663 is 9 with a remainder of 535.
Write down 9 as next digit of the result. 
Result so far: 12739.0
Deduct 5967 from 6502 and we're left with 535.
Bring next digit (1) of the dividend behind the 535 and repeat the process: 5351 / 663

Let's proceed to step 8:
If we divide 5351 by 663, we get 8 and a remainder of 47.
The next digit of our result is 8. 
Result so far: 127398.0
The remainder is 47 after subtracting 5304 from 5351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
470 divided by 663 is 0 with a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 127398.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 10:
663 goes into 4700 7 times with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 127398.07
The remainder is 59 after subtracting 4641 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
If we divide 590 by 663, we get 0 and a remainder of 590.
Write down 0 as next digit of the result. 
Result so far: 127398.07
If we take 0 away from 590, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
663 can be fit into 5900 8 times, resulting in a remainder of 596.
The number 8 becomes the next digit in our result. 
Result so far: 127398.0708
If we take 5304 away from 5900, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 13:
663 goes into 5960 8 times with a remainder of 656.
The number 8 becomes the next digit in our result. 
Result so far: 127398.07088
If we take 5304 away from 5960, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

In conclusion, the division gives 127398.07088 with a balance of 0.000656.
