We look at the division of 152994 by 191 
The aim is to understand the frequency of 191 in 152994.

Step 1:
If we divide 1 by 191, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 191

On to step 2:
When dividing 15 by 191, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 191

Let's proceed to step 3:
152 divided by 191 is 0 with a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 152 to get 152.
Grab the next digit (9) from the dividend, add it to 152, then carry on: 1529 / 191

Moving on to step 4:
The number 191 fits into 1529 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 1 after subtracting 1528 from 1529.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 191

Advancing to step 5:
The number 191 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 191

Advancing to step 6:
When dividing 194 by 191, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 801.0
Deduct 191 from 194 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 191, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 801.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
191 goes into 300 1 times with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 801.01
Subtracting 191 from 300 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
1090 divided by 191 is 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 801.015
If we subtract 955 from 1090, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
1350 divided by 191 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 801.0157
If we take 1337 away from 1350, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 191, we get 0 and a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 801.0157
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
1300 divided by 191 is 6 with a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 801.015706
Subtracting 1146 from 1300 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 13:
1540 divided by 191 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 801.0157068
Subtract 1528 from 1540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
191 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 801.0157068
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 801.0157068 and a remainder of 1.2e-07.
