We're dividing 870 by 63 
The aim is to understand the frequency of 63 in 870.

Let's proceed to step 1:
8 divided by 63 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 63

Let's proceed to step 2:
When dividing 87 by 63, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 63 from 87 to get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 63

Moving on to step 3:
If we divide 240 by 63, we get 3 and a remainder of 51.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 189 from 240 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 4:
When dividing 510 by 63, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 13.8
Subtract 504 from 510 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 5:
When dividing 60 by 63, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 13.8
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 6:
600 divided by 63 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 13.809
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
63 goes into 330 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13.8095
Subtracting 315 from 330 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
63 can be fit into 150 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 13.80952
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 13.809523
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
510 divided by 63 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 13.8095238
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
63 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 13.8095238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 13.8095238, and the remainder is 6e-08.
