Let's divide 50403029 by 636
The aim is to understand the frequency of 636 in 50403029.

Advancing to step 1:
If we divide 5 by 636, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 636

Moving on to step 2:
The number 636 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 636

On to step 3:
If we divide 504 by 636, we get 0 and a remainder of 504.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 504 leaves us with 504.
Append the next digit (0) from the dividend to 504 and continue with: 5040 / 636

Moving on to step 4:
If we divide 5040 by 636, we get 7 and a remainder of 588.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 588 after subtracting 4452 from 5040.
Bring next digit (3) of the dividend behind the 588 and repeat the process: 5883 / 636

Let's proceed to step 5:
636 goes into 5883 9 times with a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 5724 from 5883, we get 159.
Append the next digit (0) from the dividend to 159 and continue with: 1590 / 636

Let's proceed to step 6:
636 goes into 1590 2 times with a remainder of 318.
Write down 2 as next digit of the result. 
Result so far: 792.0
Subtracting 1272 from 1590 leaves us with 318.
Grab the next digit (2) from the dividend, add it to 318, then carry on: 3182 / 636

Advancing to step 7:
The number 636 fits into 3182 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 7925.0
Subtracting 3180 from 3182 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 636

Step 8:
636 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 79250.0
Subtracting 0 from 29 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
If we divide 290 by 636, we get 0 and a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 79250.0
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
The number 636 fits into 2900 4 times, leaving a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 79250.04
Deduct 2544 from 2900 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
636 can be fit into 3560 5 times, resulting in a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 79250.045
If we subtract 3180 from 3560, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 12:
If we divide 3800 by 636, we get 5 and a remainder of 620.
The number 5 becomes the next digit in our result. 
Result so far: 79250.0455
The remainder is 620 after subtracting 3180 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final outcome is 79250.0455, with a leftover of 0.0062.
