We're dividing 159407 by 63 
The aim is to understand the frequency of 63 in 159407.

On to step 1:
1 divided by 63 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 63

Let's proceed to step 2:
15 divided by 63 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 63

Let's proceed to step 3:
If we divide 159 by 63, we get 2 and a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 33 after subtracting 126 from 159.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 63

Advancing to step 4:
63 can be fit into 334 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 315 from 334 to get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 63

On to step 5:
63 goes into 190 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
If we take 189 away from 190, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 63

Advancing to step 6:
The number 63 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 2530.0
If we subtract 0 from 17, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 63 fits into 170 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 2530.2
If we take 126 away from 170, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
The number 63 fits into 440 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 2530.26
Subtract 378 from 440 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
63 can be fit into 620 9 times, resulting in a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 2530.269
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
530 divided by 63 is 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 2530.2698
If we take 504 away from 530, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
63 can be fit into 260 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2530.26984
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
63 goes into 80 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2530.269841
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
63 goes into 170 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 2530.2698412
Deduct 126 from 170 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
The number 63 fits into 440 6 times, leaving a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 2530.26984126
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 2530.26984126 with a remaining 6.2e-08.
