854375 ÷ 49 
The aim is to understand the frequency of 49 in 854375.

On to step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 49

Advancing to step 2:
85 divided by 49 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 85 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 49

Step 3:
49 goes into 364 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 343 from 364 to get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 49

On to step 4:
When dividing 213 by 49, we get 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 174.0
The remainder is 17 after subtracting 196 from 213.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 49

Advancing to step 5:
49 goes into 177 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1743.0
Subtracting 147 from 177 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 49

Advancing to step 6:
305 divided by 49 is 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 17436.0
Deduct 294 from 305 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 49, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 17436.2
The remainder is 12 after subtracting 98 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 17436.22
If we subtract 98 from 120, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 17436.22, with a leftover of 0.022.
