994221 ÷ 63 
The aim is to understand the frequency of 63 in 994221.

Advancing to step 1:
If we divide 9 by 63, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 63

Going ahead to step 2:
The number 63 fits into 99 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 63 from 99 to get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 63

Step 3:
If we divide 364 by 63, we get 5 and a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 315 away from 364, we end up with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 63

Moving on to step 4:
63 can be fit into 492 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 157.0
Subtract 441 from 492 to get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 63

Moving on to step 5:
63 can be fit into 512 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1578.0
Subtract 504 from 512 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 63

Let's proceed to step 6:
63 goes into 81 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 15781.0
Subtract 63 from 81 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
If we divide 180 by 63, we get 2 and a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 15781.2
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
The number 63 fits into 540 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 15781.28
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 63, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 15781.285
The remainder is 45 after subtracting 315 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
63 can be fit into 450 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 15781.2857
If we subtract 441 from 450, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
The number 63 fits into 90 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 15781.28571
The remainder is 27 after subtracting 63 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
If we divide 270 by 63, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 15781.285714
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
The number 63 fits into 180 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 15781.2857142
If we subtract 126 from 180, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
63 goes into 540 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 15781.28571428
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 15781.28571428 with a balance of 3.6e-08.
