Let's divide 81885665 by 191
The aim is to understand the frequency of 191 in 81885665.

On to step 1:
8 divided by 191 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 191

Moving on to step 2:
191 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 191

Going ahead to step 3:
191 can be fit into 818 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 764 from 818 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 191

Going ahead to step 4:
548 divided by 191 is 2 with a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 382 from 548 and we're left with 166.
Include the next digit (5) from the dividend after 166, then repeat: 1665 / 191

Let's proceed to step 5:
1665 divided by 191 is 8 with a remainder of 137.
Record the quotient 8 as the next digit in the result. 
Result so far: 428.0
Subtract 1528 from 1665 to get 137.
Grab the next digit (6) from the dividend, add it to 137, then carry on: 1376 / 191

Going ahead to step 6:
The number 191 fits into 1376 7 times, leaving a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 4287.0
If we take 1337 away from 1376, we end up with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 191

Going ahead to step 7:
The number 191 fits into 396 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 42872.0
Subtracting 382 from 396 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 191

On to step 8:
145 divided by 191 is 0 with a remainder of 145.
Record the quotient 0 as the next digit in the result. 
Result so far: 428720.0
Subtract 0 from 145 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
191 goes into 1450 7 times with a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 428720.7
Subtracting 1337 from 1450 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 10:
191 goes into 1130 5 times with a remainder of 175.
The next digit of our result is 5. 
Result so far: 428720.75
Deduct 955 from 1130 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
The number 191 fits into 1750 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 428720.759
Subtracting 1719 from 1750 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
191 can be fit into 310 1 times, resulting in a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 428720.7591
Deduct 191 from 310 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 13:
When dividing 1190 by 191, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 428720.75916
If we take 1146 away from 1190, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
When dividing 440 by 191, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 428720.759162
If we subtract 382 from 440, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
The number 191 fits into 580 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 428720.7591623
Subtract 573 from 580 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
191 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 428720.7591623
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 428720.7591623 and a remainder of 7e-08.
