We're dividing 49642754 by 357 
The aim is to understand the frequency of 357 in 49642754.

On to step 1:
If we divide 4 by 357, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 357

Going ahead to step 2:
The number 357 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 357

Moving on to step 3:
496 divided by 357 is 1 with a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 357 from 496 to get 139.
Append the next digit (4) from the dividend to 139 and continue with: 1394 / 357

Let's proceed to step 4:
357 can be fit into 1394 3 times, resulting in a remainder of 323.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1071 from 1394 leaves us with 323.
Grab the next digit (2) from the dividend, add it to 323, then carry on: 3232 / 357

Step 5:
357 goes into 3232 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 139.0
Deduct 3213 from 3232 and we're left with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 357

Going ahead to step 6:
The number 357 fits into 197 0 times, leaving a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 1390.0
Deduct 0 from 197 and we're left with 197.
Bring next digit (5) of the dividend behind the 197 and repeat the process: 1975 / 357

Let's proceed to step 7:
357 goes into 1975 5 times with a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 13905.0
The remainder is 190 after subtracting 1785 from 1975.
Append the next digit (4) from the dividend to 190 and continue with: 1904 / 357

Moving on to step 8:
When dividing 1904 by 357, we get 5 with a remainder of 119.
Use 5 as the next digit of our solution. 
Result so far: 139055.0
If we take 1785 away from 1904, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
If we divide 1190 by 357, we get 3 and a remainder of 119.
Write down 3 as next digit of the result. 
Result so far: 139055.3
The remainder is 119 after subtracting 1071 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 10:
The number 357 fits into 1190 3 times, leaving a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 139055.33
Subtract 1071 from 1190 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The quotient of the division is 139055.33, and the remainder is 0.119.
