63438917 divided by 984 
We want to figure out the number of times 63438917 can be divided by 984.

On to step 1:
984 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 984

Moving on to step 2:
984 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 984

Let's proceed to step 3:
984 can be fit into 634 0 times, resulting in a remainder of 634.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 634 after subtracting 0 from 634.
Grab the next digit (3) from the dividend, add it to 634, then carry on: 6343 / 984

Going ahead to step 4:
When dividing 6343 by 984, we get 6 with a remainder of 439.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5904 from 6343 and we're left with 439.
Fetch the next digit (8) from the dividend, attach it to 439 and continue: 4398 / 984

Going ahead to step 5:
When dividing 4398 by 984, we get 4 with a remainder of 462.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 3936 from 4398 leaves us with 462.
Bring next digit (9) of the dividend behind the 462 and repeat the process: 4629 / 984

Going ahead to step 6:
If we divide 4629 by 984, we get 4 and a remainder of 693.
Put 4 as the next digit of the answer. 
Result so far: 644.0
If we subtract 3936 from 4629, we get 693.
Fetch the next digit (1) from the dividend, attach it to 693 and continue: 6931 / 984

Moving on to step 7:
984 can be fit into 6931 7 times, resulting in a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 6447.0
If we take 6888 away from 6931, we end up with 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 984

On to step 8:
437 divided by 984 is 0 with a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 64470.0
If we subtract 0 from 437, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 9:
The number 984 fits into 4370 4 times, leaving a remainder of 434.
The number 4 becomes the next digit in our result. 
Result so far: 64470.4
The remainder is 434 after subtracting 3936 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 10:
984 can be fit into 4340 4 times, resulting in a remainder of 404.
The next digit of our result is 4. 
Result so far: 64470.44
Subtracting 3936 from 4340 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 64470.44, with a leftover of 0.404.
