6345872 divided by 326 
The aim is to understand the frequency of 326 in 6345872.

Let's proceed to step 1:
If we divide 6 by 326, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 326

Moving on to step 2:
326 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 326

Advancing to step 3:
The number 326 fits into 634 1 times, leaving a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 326 from 634, we get 308.
Append the next digit (5) from the dividend to 308 and continue with: 3085 / 326

Let's proceed to step 4:
When dividing 3085 by 326, we get 9 with a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 2934 from 3085 and we're left with 151.
Include the next digit (8) from the dividend after 151, then repeat: 1518 / 326

On to step 5:
326 can be fit into 1518 4 times, resulting in a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 194.0
The remainder is 214 after subtracting 1304 from 1518.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 326

On to step 6:
If we divide 2147 by 326, we get 6 and a remainder of 191.
Record the quotient 6 as the next digit in the result. 
Result so far: 1946.0
The remainder is 191 after subtracting 1956 from 2147.
Bring next digit (2) of the dividend behind the 191 and repeat the process: 1912 / 326

Let's proceed to step 7:
If we divide 1912 by 326, we get 5 and a remainder of 282.
Use 5 as the next digit of our solution. 
Result so far: 19465.0
The remainder is 282 after subtracting 1630 from 1912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 8:
When dividing 2820 by 326, we get 8 with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 19465.8
If we take 2608 away from 2820, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 9:
When dividing 2120 by 326, we get 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 19465.86
If we take 1956 away from 2120, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
1640 divided by 326 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19465.865
Deduct 1630 from 1640 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
326 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 19465.865
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
1000 divided by 326 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 19465.86503
If we take 978 away from 1000, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
326 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 19465.86503
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
If we divide 2200 by 326, we get 6 and a remainder of 244.
The next digit of our result is 6. 
Result so far: 19465.8650306
If we take 1956 away from 2200, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 15:
2440 divided by 326 is 7 with a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 19465.86503067
The remainder is 158 after subtracting 2282 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

After the division, we end up with 19465.86503067 and a remainder of 1.58e-07.
