869402 ÷ 63 
The aim is to understand the frequency of 63 in 869402.

Advancing to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 63

Going ahead to step 2:
The number 63 fits into 86 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 63 from 86 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 63

Going ahead to step 3:
63 can be fit into 239 3 times, resulting in a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 189 away from 239, we end up with 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 63

On to step 4:
If we divide 504 by 63, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 138.0
Subtract 504 from 504 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 63

Let's proceed to step 5:
The number 63 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1380.0
If we subtract 0 from 0, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 63

Step 6:
63 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 13800.0
Subtract 0 from 2 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
63 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13800.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 63, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 13800.03
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
63 goes into 110 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 13800.031
Subtracting 63 from 110 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
470 divided by 63 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 13800.0317
Deduct 441 from 470 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
The number 63 fits into 290 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 13800.03174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
63 goes into 380 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13800.031746
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
63 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13800.031746
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
63 can be fit into 200 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13800.03174603
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 13800.03174603 and a remainder of 1.1e-08.
