63777495 divided by 999 
The aim is to understand the frequency of 999 in 63777495.

Step 1:
999 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 999

Step 2:
999 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 999

Let's proceed to step 3:
999 can be fit into 637 0 times, resulting in a remainder of 637.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 637 and we're left with 637.
Take the next digit (7) from the dividend and append it to 637, then repeat: 6377 / 999

Going ahead to step 4:
When dividing 6377 by 999, we get 6 with a remainder of 383.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5994 away from 6377, we end up with 383.
Grab the next digit (7) from the dividend, add it to 383, then carry on: 3837 / 999

Going ahead to step 5:
If we divide 3837 by 999, we get 3 and a remainder of 840.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 2997 from 3837, we get 840.
Grab the next digit (4) from the dividend, add it to 840, then carry on: 8404 / 999

Moving on to step 6:
999 can be fit into 8404 8 times, resulting in a remainder of 412.
Write down 8 as next digit of the result. 
Result so far: 638.0
Subtract 7992 from 8404 to get 412.
Fetch the next digit (9) from the dividend, attach it to 412 and continue: 4129 / 999

Going ahead to step 7:
If we divide 4129 by 999, we get 4 and a remainder of 133.
Put 4 as the next digit of the answer. 
Result so far: 6384.0
If we subtract 3996 from 4129, we get 133.
Take the next digit (5) from the dividend and append it to 133, then repeat: 1335 / 999

On to step 8:
If we divide 1335 by 999, we get 1 and a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 63841.0
Deduct 999 from 1335 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
The number 999 fits into 3360 3 times, leaving a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 63841.3
Subtracting 2997 from 3360 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 10:
3630 divided by 999 is 3 with a remainder of 633.
Use 3 as the next digit of our solution. 
Result so far: 63841.33
If we subtract 2997 from 3630, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

The quotient of the division is 63841.33, and the remainder is 0.633.
