Let's divide 689601 by 63
The aim is to understand the frequency of 63 in 689601.

Step 1:
6 divided by 63 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 63

Let's proceed to step 2:
The number 63 fits into 68 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 63 away from 68, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 63

Let's proceed to step 3:
When dividing 59 by 63, we get 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 59 to get 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 63

On to step 4:
When dividing 596 by 63, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 29 after subtracting 567 from 596.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 63

Step 5:
If we divide 290 by 63, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 1094.0
If we take 252 away from 290, we end up with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 63

Moving on to step 6:
When dividing 381 by 63, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 10946.0
Subtracting 378 from 381 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 63 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10946.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 63, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 10946.04
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
When dividing 480 by 63, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 10946.047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
The number 63 fits into 390 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 10946.0476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 63 fits into 120 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 10946.04761
Subtracting 63 from 120 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 10946.047619
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 63 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10946.047619
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
When dividing 300 by 63, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10946.04761904
Subtract 252 from 300 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 10946.04761904, with a leftover of 4.8e-08.
