We look at the division of 51308315 by 191 
The aim is to understand the frequency of 191 in 51308315.

Let's proceed to step 1:
5 divided by 191 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 191

On to step 2:
When dividing 51 by 191, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 191

Let's proceed to step 3:
191 can be fit into 513 2 times, resulting in a remainder of 131.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 382 from 513 leaves us with 131.
Bring next digit (0) of the dividend behind the 131 and repeat the process: 1310 / 191

Advancing to step 4:
If we divide 1310 by 191, we get 6 and a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 1146 from 1310, we get 164.
Grab the next digit (8) from the dividend, add it to 164, then carry on: 1648 / 191

Going ahead to step 5:
191 can be fit into 1648 8 times, resulting in a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
Subtracting 1528 from 1648 leaves us with 120.
Fetch the next digit (3) from the dividend, attach it to 120 and continue: 1203 / 191

Let's proceed to step 6:
191 can be fit into 1203 6 times, resulting in a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 2686.0
If we subtract 1146 from 1203, we get 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 191

Moving on to step 7:
The number 191 fits into 571 2 times, leaving a remainder of 189.
Use 2 as the next digit of our solution. 
Result so far: 26862.0
The remainder is 189 after subtracting 382 from 571.
Take the next digit (5) from the dividend and append it to 189, then repeat: 1895 / 191

On to step 8:
When dividing 1895 by 191, we get 9 with a remainder of 176.
Put 9 as the next digit of the answer. 
Result so far: 268629.0
If we subtract 1719 from 1895, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 9:
191 goes into 1760 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 268629.9
The remainder is 41 after subtracting 1719 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
191 can be fit into 410 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 268629.92
Deduct 382 from 410 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
If we divide 280 by 191, we get 1 and a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 268629.921
The remainder is 89 after subtracting 191 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 12:
191 goes into 890 4 times with a remainder of 126.
The next digit of our result is 4. 
Result so far: 268629.9214
Deduct 764 from 890 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
When dividing 1260 by 191, we get 6 with a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 268629.92146
Subtracting 1146 from 1260 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 14:
The number 191 fits into 1140 5 times, leaving a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 268629.921465
Subtracting 955 from 1140 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
The number 191 fits into 1850 9 times, leaving a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 268629.9214659
Deduct 1719 from 1850 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 16:
191 goes into 1310 6 times with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 268629.92146596
Subtracting 1146 from 1310 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final result is 268629.92146596 with a remainder of 1.64e-07.
