We divide 816457 by 49
The aim is to understand the frequency of 49 in 816457.

Moving on to step 1:
49 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 49

Moving on to step 2:
If we divide 81 by 49, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 32 after subtracting 49 from 81.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 49

Step 3:
When dividing 326 by 49, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 294 away from 326, we end up with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 49

Let's proceed to step 4:
324 divided by 49 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Subtracting 294 from 324 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 49

Let's proceed to step 5:
49 can be fit into 305 6 times, resulting in a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 1666.0
The remainder is 11 after subtracting 294 from 305.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 49

Moving on to step 6:
When dividing 117 by 49, we get 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 16662.0
If we subtract 98 from 117, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 49 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 16662.3
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
430 divided by 49 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 16662.38
If we take 392 away from 430, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
49 goes into 380 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 16662.387
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
370 divided by 49 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 16662.3877
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 16662.3877, with a leftover of 0.00027.
