Let's divide 881012 by 49
The aim is to understand the frequency of 49 in 881012.

On to step 1:
If we divide 8 by 49, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our 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

Let's proceed to step 2:
The number 49 fits into 88 1 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 49

Going ahead to step 3:
391 divided by 49 is 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 343 from 391 and we're left with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 49

Going ahead to step 4:
The number 49 fits into 480 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Deduct 441 from 480 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 49

On to step 5:
If we divide 391 by 49, we get 7 and a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 1797.0
Subtract 343 from 391 to get 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 49

Moving on to step 6:
The number 49 fits into 482 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 17979.0
If we subtract 441 from 482, we 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 7:
410 divided by 49 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17979.8
Deduct 392 from 410 and we're left 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.

Let's proceed to step 8:
49 can be fit into 180 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 17979.83
Subtracting 147 from 180 leaves us 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.

Let's proceed to step 9:
When dividing 330 by 49, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 17979.836
Subtracting 294 from 330 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
49 can be fit into 360 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17979.8367
Deduct 343 from 360 and we're left 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.

Moving on to step 11:
The number 49 fits into 170 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 17979.83673
The remainder is 23 after subtracting 147 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
If we divide 230 by 49, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 17979.836734
If we take 196 away from 230, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
340 divided by 49 is 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 17979.8367346
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
460 divided by 49 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 17979.83673469
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 17979.83673469 with a balance of 1.9e-08.
