Let's divide 639887 by 63
The aim is to understand the frequency of 63 in 639887.

Moving on to step 1:
63 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 63

Advancing to step 2:
The number 63 fits into 63 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 63 away from 63, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 63

Let's proceed to step 3:
63 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 63

Step 4:
When dividing 98 by 63, we get 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 63 away from 98, we end up with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 63

Moving on to step 5:
If we divide 358 by 63, we get 5 and a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 1015.0
Subtract 315 from 358 to get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 63

Going ahead to step 6:
437 divided by 63 is 6 with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 10156.0
The remainder is 59 after subtracting 378 from 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
63 goes into 590 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 10156.9
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
230 divided by 63 is 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 10156.93
Subtract 189 from 230 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 63 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 10156.936
The remainder is 32 after subtracting 378 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 63 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 10156.9365
Subtract 315 from 320 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 63 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 10156.9365
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
500 divided by 63 is 7 with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 10156.936507
If we take 441 away from 500, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 13:
If we divide 590 by 63, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 10156.9365079
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
The number 63 fits into 230 3 times, leaving a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 10156.93650793
Subtract 189 from 230 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

After the division, we end up with 10156.93650793 and a remainder of 4.1e-08.
