81025221 ÷ 49 
The aim is to understand the frequency of 49 in 81025221.

Advancing 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
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 49

Advancing to step 2:
81 divided by 49 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 81 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 49

Step 3:
49 can be fit into 320 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 294 away from 320, we end up with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 49

On to step 4:
When dividing 262 by 49, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we subtract 245 from 262, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 49

Going ahead to step 5:
If we divide 175 by 49, we get 3 and a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 1653.0
Subtract 147 from 175 to get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 49

Step 6:
The number 49 fits into 282 5 times, leaving a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 16535.0
If we subtract 245 from 282, we get 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 49

Let's proceed to step 7:
The number 49 fits into 372 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 165357.0
If we take 343 away from 372, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 49

Going ahead to step 8:
291 divided by 49 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 1653575.0
If we subtract 245 from 291, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
The number 49 fits into 460 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 1653575.9
If we subtract 441 from 460, 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.

Going ahead to step 10:
If we divide 190 by 49, we get 3 and a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 1653575.93
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.

On to step 11:
When dividing 430 by 49, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 1653575.938
Deduct 392 from 430 and we're left 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.

On to step 12:
The number 49 fits into 380 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 1653575.9387
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
49 can be fit into 370 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1653575.93877
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 1653575.93877 with a balance of 2.7e-05.
