We look at the division of 889771 by 49 
The aim is to understand the frequency of 49 in 889771.

Step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 49

Going ahead to step 2:
When dividing 88 by 49, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 49 from 88 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 49

Advancing to step 3:
399 divided by 49 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 7 after subtracting 392 from 399.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 49

Going ahead to step 4:
If we divide 77 by 49, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Subtracting 49 from 77 leaves us with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 49

Moving on to step 5:
If we divide 287 by 49, we get 5 and a remainder of 42.
The next digit of our result is 5. 
Result so far: 1815.0
Deduct 245 from 287 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 49

Moving on to step 6:
The number 49 fits into 421 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 18158.0
The remainder is 29 after subtracting 392 from 421.
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 7:
If we divide 290 by 49, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 18158.5
If we subtract 245 from 290, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
49 goes into 450 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 18158.59
The remainder is 9 after subtracting 441 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
49 can be fit into 90 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 18158.591
Subtract 49 from 90 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
If we divide 410 by 49, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 18158.5918
Subtracting 392 from 410 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 49 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 18158.59183
Deduct 147 from 180 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
330 divided by 49 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 18158.591836
If we subtract 294 from 330, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 49, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 18158.5918367
Subtracting 343 from 360 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
49 can be fit into 170 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 18158.59183673
If we take 147 away from 170, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 18158.59183673, with a leftover of 2.3e-08.
