We look at the division of 17929177 by 201 
The aim is to understand the frequency of 201 in 17929177.

Step 1:
201 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 201

Let's proceed to step 2:
If we divide 17 by 201, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 201

Going ahead to step 3:
The number 201 fits into 179 0 times, leaving a remainder of 179.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 179 leaves us with 179.
Append the next digit (2) from the dividend to 179 and continue with: 1792 / 201

Advancing to step 4:
If we divide 1792 by 201, we get 8 and a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 184 after subtracting 1608 from 1792.
Bring next digit (9) of the dividend behind the 184 and repeat the process: 1849 / 201

Step 5:
The number 201 fits into 1849 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 1809 away from 1849, we end up with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 201

Advancing to step 6:
When dividing 401 by 201, we get 1 with a remainder of 200.
The next digit of our result is 1. 
Result so far: 891.0
The remainder is 200 after subtracting 201 from 401.
Grab the next digit (7) from the dividend, add it to 200, then carry on: 2007 / 201

Step 7:
If we divide 2007 by 201, we get 9 and a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 8919.0
Subtracting 1809 from 2007 leaves us with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 201

Let's proceed to step 8:
When dividing 1987 by 201, we get 9 with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 89199.0
Deduct 1809 from 1987 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
1780 divided by 201 is 8 with a remainder of 172.
The next digit of our result is 8. 
Result so far: 89199.8
The remainder is 172 after subtracting 1608 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
When dividing 1720 by 201, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 89199.88
Subtract 1608 from 1720 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 89199.88 with a remainder of 0.112.
