63973110 ÷ 635 
The aim is to understand the frequency of 635 in 63973110.

Let's proceed to step 1:
When dividing 6 by 635, we get 0 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.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 635

Advancing to step 2:
635 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 635

Moving on to step 3:
When dividing 639 by 635, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 635 from 639.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 635

Advancing to step 4:
The number 635 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 635

On to step 5:
635 can be fit into 473 0 times, resulting in a remainder of 473.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 473 leaves us with 473.
Append the next digit (1) from the dividend to 473 and continue with: 4731 / 635

Advancing to step 6:
635 goes into 4731 7 times with a remainder of 286.
Write down 7 as next digit of the result. 
Result so far: 1007.0
Deduct 4445 from 4731 and we're left with 286.
Bring next digit (1) of the dividend behind the 286 and repeat the process: 2861 / 635

On to step 7:
If we divide 2861 by 635, we get 4 and a remainder of 321.
Record the quotient 4 as the next digit in the result. 
Result so far: 10074.0
Deduct 2540 from 2861 and we're left with 321.
Take the next digit (0) from the dividend and append it to 321, then repeat: 3210 / 635

Advancing to step 8:
635 goes into 3210 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 100745.0
If we subtract 3175 from 3210, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
635 can be fit into 350 0 times, resulting in a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 100745.0
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
If we divide 3500 by 635, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 100745.05
The remainder is 325 after subtracting 3175 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 11:
3250 divided by 635 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 100745.055
If we take 3175 away from 3250, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 100745.055 with a remaining 0.0075.
