We're dividing 17102217 by 121 
The aim is to understand the frequency of 121 in 17102217.

On to step 1:
121 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 121

Moving on to step 2:
17 divided by 121 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 121

Let's proceed to step 3:
When dividing 171 by 121, we get 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 121 from 171 leaves us with 50.
Take the next digit (0) from the dividend and append it to 50, then repeat: 500 / 121

Moving on to step 4:
500 divided by 121 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 16 after subtracting 484 from 500.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 121

Advancing to step 5:
If we divide 162 by 121, we get 1 and a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 121 from 162 leaves us with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 121

Let's proceed to step 6:
If we divide 412 by 121, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 1413.0
Subtract 363 from 412 to get 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 121

Let's proceed to step 7:
If we divide 491 by 121, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14134.0
If we subtract 484 from 491, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 121

Let's proceed to step 8:
If we divide 77 by 121, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 141340.0
Subtract 0 from 77 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
770 divided by 121 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 141340.6
Subtracting 726 from 770 leaves us 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.

Step 10:
121 can be fit into 440 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 141340.63
If we subtract 363 from 440, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
121 goes into 770 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 141340.636
Deduct 726 from 770 and we're left 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.

Let's proceed to step 12:
When dividing 440 by 121, we get 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 141340.6363
Subtracting 363 from 440 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 13:
The number 121 fits into 770 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 141340.63636
If we take 726 away from 770, 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:
121 can be fit into 440 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 141340.636363
If we take 363 away from 440, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 15:
121 goes into 770 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 141340.6363636
Deduct 726 from 770 and we're left 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.

Let's proceed to step 16:
When dividing 440 by 121, we get 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 141340.63636363
The remainder is 77 after subtracting 363 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final result is 141340.63636363 with a remainder of 7.7e-08.
