53397105 ÷ 635 
The aim is to understand the frequency of 635 in 53397105.

Let's proceed to step 1:
When dividing 5 by 635, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 635

Going ahead to step 2:
The number 635 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 635

Moving on to step 3:
If we divide 533 by 635, we get 0 and a remainder of 533.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 533 leaves us with 533.
Take the next digit (9) from the dividend and append it to 533, then repeat: 5339 / 635

On to step 4:
When dividing 5339 by 635, we get 8 with a remainder of 259.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 5080 from 5339 to get 259.
Take the next digit (7) from the dividend and append it to 259, then repeat: 2597 / 635

Step 5:
2597 divided by 635 is 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 2540 from 2597 and we're left with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 635

Advancing to step 6:
The number 635 fits into 571 0 times, leaving a remainder of 571.
Write down 0 as next digit of the result. 
Result so far: 840.0
The remainder is 571 after subtracting 0 from 571.
Grab the next digit (0) from the dividend, add it to 571, then carry on: 5710 / 635

On to step 7:
635 can be fit into 5710 8 times, resulting in a remainder of 630.
Use 8 as the next digit of our solution. 
Result so far: 8408.0
Deduct 5080 from 5710 and we're left with 630.
Grab the next digit (5) from the dividend, add it to 630, then carry on: 6305 / 635

Step 8:
If we divide 6305 by 635, we get 9 and a remainder of 590.
Use 9 as the next digit of our solution. 
Result so far: 84089.0
Subtracting 5715 from 6305 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 9:
If we divide 5900 by 635, we get 9 and a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 84089.9
Subtract 5715 from 5900 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 10:
The number 635 fits into 1850 2 times, leaving a remainder of 580.
The next digit of our result is 2. 
Result so far: 84089.92
Subtract 1270 from 1850 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 11:
5800 divided by 635 is 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 84089.929
If we subtract 5715 from 5800, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
850 divided by 635 is 1 with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 84089.9291
Subtracting 635 from 850 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 13:
The number 635 fits into 2150 3 times, leaving a remainder of 245.
Use 3 as the next digit of our solution. 
Result so far: 84089.92913
Subtract 1905 from 2150 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 14:
The number 635 fits into 2450 3 times, leaving a remainder of 545.
Use 3 as the next digit of our solution. 
Result so far: 84089.929133
The remainder is 545 after subtracting 1905 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

After the division, we end up with 84089.929133 and a remainder of 5.45e-05.
