Let's divide 45458739 by 636
The aim is to understand the frequency of 636 in 45458739.

Advancing to step 1:
636 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 636

Moving on to step 2:
When dividing 45 by 636, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 636

Advancing to step 3:
If we divide 454 by 636, we get 0 and a remainder of 454.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 454, we end up with 454.
Grab the next digit (5) from the dividend, add it to 454, then carry on: 4545 / 636

Going ahead to step 4:
The number 636 fits into 4545 7 times, leaving a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4452 from 4545, we get 93.
Grab the next digit (8) from the dividend, add it to 93, then carry on: 938 / 636

Moving on to step 5:
If we divide 938 by 636, we get 1 and a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 636 from 938 to get 302.
Take the next digit (7) from the dividend and append it to 302, then repeat: 3027 / 636

Let's proceed to step 6:
636 goes into 3027 4 times with a remainder of 483.
Use 4 as the next digit of our solution. 
Result so far: 714.0
If we subtract 2544 from 3027, we get 483.
Append the next digit (3) from the dividend to 483 and continue with: 4833 / 636

Advancing to step 7:
When dividing 4833 by 636, we get 7 with a remainder of 381.
Use 7 as the next digit of our solution. 
Result so far: 7147.0
If we subtract 4452 from 4833, we get 381.
Bring next digit (9) of the dividend behind the 381 and repeat the process: 3819 / 636

Let's proceed to step 8:
If we divide 3819 by 636, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 71476.0
The remainder is 3 after subtracting 3816 from 3819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 636, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 71476.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 636 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 71476.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 71476.0 and a remainder of 0.3.
