90097604 ÷ 326 
The aim is to understand the frequency of 326 in 90097604.

Step 1:
The number 326 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 326

Step 2:
326 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 326

Let's proceed to step 3:
If we divide 900 by 326, we get 2 and a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 652 from 900 and we're left with 248.
Take the next digit (9) from the dividend and append it to 248, then repeat: 2489 / 326

Moving on to step 4:
When dividing 2489 by 326, we get 7 with a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 2282 from 2489 to get 207.
Take the next digit (7) from the dividend and append it to 207, then repeat: 2077 / 326

Going ahead to step 5:
When dividing 2077 by 326, we get 6 with a remainder of 121.
Use 6 as the next digit of our solution. 
Result so far: 276.0
Deduct 1956 from 2077 and we're left with 121.
Grab the next digit (6) from the dividend, add it to 121, then carry on: 1216 / 326

Going ahead to step 6:
326 can be fit into 1216 3 times, resulting in a remainder of 238.
Write down 3 as next digit of the result. 
Result so far: 2763.0
If we subtract 978 from 1216, we get 238.
Bring next digit (0) of the dividend behind the 238 and repeat the process: 2380 / 326

Moving on to step 7:
2380 divided by 326 is 7 with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 27637.0
Subtract 2282 from 2380 to get 98.
Take the next digit (4) from the dividend and append it to 98, then repeat: 984 / 326

Moving on to step 8:
If we divide 984 by 326, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 276373.0
If we take 978 away from 984, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
326 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 276373.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 326, we get 1 with a remainder of 274.
The next digit of our result is 1. 
Result so far: 276373.01
Deduct 326 from 600 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
2740 divided by 326 is 8 with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 276373.018
Subtract 2608 from 2740 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
If we divide 1320 by 326, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 276373.0184
If we subtract 1304 from 1320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 326, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 276373.0184
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
The number 326 fits into 1600 4 times, leaving a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 276373.018404
Subtract 1304 from 1600 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 15:
326 can be fit into 2960 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 276373.0184049
If we subtract 2934 from 2960, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 16:
If we divide 260 by 326, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 276373.0184049
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 276373.0184049, and the remainder is 2.6e-07.
