We're dividing 13465903 by 636 
The aim is to understand the frequency of 636 in 13465903.

Moving on to step 1:
If we divide 1 by 636, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 636

Let's proceed to step 2:
13 divided by 636 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 636

Moving on to step 3:
The number 636 fits into 134 0 times, leaving a remainder of 134.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 134 to get 134.
Fetch the next digit (6) from the dividend, attach it to 134 and continue: 1346 / 636

Step 4:
636 can be fit into 1346 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1272 from 1346 and we're left with 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 636

Step 5:
When dividing 745 by 636, we get 1 with a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 636 from 745 to get 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 636

Advancing to step 6:
When dividing 1099 by 636, we get 1 with a remainder of 463.
The next digit of our result is 1. 
Result so far: 211.0
Deduct 636 from 1099 and we're left with 463.
Append the next digit (0) from the dividend to 463 and continue with: 4630 / 636

Moving on to step 7:
4630 divided by 636 is 7 with a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 2117.0
Subtract 4452 from 4630 to get 178.
Take the next digit (3) from the dividend and append it to 178, then repeat: 1783 / 636

Going ahead to step 8:
When dividing 1783 by 636, we get 2 with a remainder of 511.
Record the quotient 2 as the next digit in the result. 
Result so far: 21172.0
If we take 1272 away from 1783, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 9:
The number 636 fits into 5110 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 21172.8
Deduct 5088 from 5110 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
If we divide 220 by 636, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 21172.8
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
636 goes into 2200 3 times with a remainder of 292.
Put 3 as the next digit of the answer. 
Result so far: 21172.803
If we subtract 1908 from 2200, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 12:
636 goes into 2920 4 times with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 21172.8034
Deduct 2544 from 2920 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 13:
If we divide 3760 by 636, we get 5 and a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 21172.80345
If we take 3180 away from 3760, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 14:
When dividing 5800 by 636, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 21172.803459
Subtract 5724 from 5800 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 15:
The number 636 fits into 760 1 times, leaving a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 21172.8034591
If we take 636 away from 760, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 16:
636 goes into 1240 1 times with a remainder of 604.
Record the quotient 1 as the next digit in the result. 
Result so far: 21172.80345911
The remainder is 604 after subtracting 636 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The quotient of the division is 21172.80345911, and the remainder is 6.04e-07.
