We look at the division of 77193401 by 326 
The aim is to understand the frequency of 326 in 77193401.

Moving on to step 1:
When dividing 7 by 326, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 326

Advancing to step 2:
When dividing 77 by 326, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 326

On to step 3:
326 goes into 771 2 times with a remainder of 119.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 652 from 771 to get 119.
Grab the next digit (9) from the dividend, add it to 119, then carry on: 1199 / 326

Let's proceed to step 4:
The number 326 fits into 1199 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 221 after subtracting 978 from 1199.
Fetch the next digit (3) from the dividend, attach it to 221 and continue: 2213 / 326

Advancing to step 5:
326 goes into 2213 6 times with a remainder of 257.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
If we subtract 1956 from 2213, we get 257.
Take the next digit (4) from the dividend and append it to 257, then repeat: 2574 / 326

Going ahead to step 6:
When dividing 2574 by 326, we get 7 with a remainder of 292.
Record the quotient 7 as the next digit in the result. 
Result so far: 2367.0
Subtract 2282 from 2574 to get 292.
Fetch the next digit (0) from the dividend, attach it to 292 and continue: 2920 / 326

Let's proceed to step 7:
If we divide 2920 by 326, we get 8 and a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 23678.0
The remainder is 312 after subtracting 2608 from 2920.
Bring next digit (1) of the dividend behind the 312 and repeat the process: 3121 / 326

Let's proceed to step 8:
If we divide 3121 by 326, we get 9 and a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 236789.0
If we take 2934 away from 3121, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 9:
The number 326 fits into 1870 5 times, leaving a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 236789.5
Deduct 1630 from 1870 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
2400 divided by 326 is 7 with a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 236789.57
Subtract 2282 from 2400 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
If we divide 1180 by 326, we get 3 and a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 236789.573
If we take 978 away from 1180, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 12:
326 goes into 2020 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 236789.5736
Subtract 1956 from 2020 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
640 divided by 326 is 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 236789.57361
If we take 326 away from 640, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 14:
326 can be fit into 3140 9 times, resulting in a remainder of 206.
Write down 9 as next digit of the result. 
Result so far: 236789.573619
The remainder is 206 after subtracting 2934 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 15:
The number 326 fits into 2060 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 236789.5736196
Deduct 1956 from 2060 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 16:
326 goes into 1040 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 236789.57361963
If we subtract 978 from 1040, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 236789.57361963, and the remainder is 6.2e-08.
