52911791 ÷ 191 
The aim is to understand the frequency of 191 in 52911791.

Step 1:
The number 191 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 191

Let's proceed to step 2:
191 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 191

Let's proceed to step 3:
191 goes into 529 2 times with a remainder of 147.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 382 from 529 to get 147.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 191

Let's proceed to step 4:
191 goes into 1471 7 times with a remainder of 134.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 134 after subtracting 1337 from 1471.
Grab the next digit (1) from the dividend, add it to 134, then carry on: 1341 / 191

On to step 5:
191 goes into 1341 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
Subtracting 1337 from 1341 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 191

Going ahead to step 6:
When dividing 47 by 191, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 2770.0
If we subtract 0 from 47, we get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 191

Step 7:
191 can be fit into 479 2 times, resulting in a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 27702.0
Deduct 382 from 479 and we're left with 97.
Fetch the next digit (1) from the dividend, attach it to 97 and continue: 971 / 191

Going ahead to step 8:
When dividing 971 by 191, we get 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 277025.0
Deduct 955 from 971 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
If we divide 160 by 191, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 277025.0
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
If we divide 1600 by 191, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 277025.08
Deduct 1528 from 1600 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
If we divide 720 by 191, we get 3 and a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 277025.083
If we take 573 away from 720, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 12:
The number 191 fits into 1470 7 times, leaving a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 277025.0837
Deduct 1337 from 1470 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 13:
If we divide 1330 by 191, we get 6 and a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 277025.08376
Deduct 1146 from 1330 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 14:
When dividing 1840 by 191, we get 9 with a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 277025.083769
Subtracting 1719 from 1840 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 15:
191 can be fit into 1210 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 277025.0837696
Deduct 1146 from 1210 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
The number 191 fits into 640 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 277025.08376963
If we subtract 573 from 640, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 277025.08376963 with a remainder of 6.7e-08.
