321591 divided by 14 
The aim is to understand the frequency of 14 in 321591.

Advancing to step 1:
14 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 14

Let's proceed to step 2:
The number 14 fits into 32 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 28 from 32, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 14

Advancing to step 3:
14 goes into 41 2 times with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 13 after subtracting 28 from 41.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 14

Going ahead to step 4:
If we divide 135 by 14, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 229.0
Subtract 126 from 135 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 14

Moving on to step 5:
If we divide 99 by 14, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 2297.0
If we subtract 98 from 99, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 14

Advancing to step 6:
If we divide 11 by 14, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 22970.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
14 can be fit into 110 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 22970.7
Deduct 98 from 110 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 22970.78
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
14 goes into 80 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 22970.785
If we subtract 70 from 80, we get 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 10:
When dividing 100 by 14, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 22970.7857
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
If we divide 20 by 14, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 22970.78571
Subtracting 14 from 20 leaves us 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.

Moving on to step 12:
14 goes into 60 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 22970.785714
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
14 goes into 40 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 22970.7857142
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 22970.78571428
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 22970.78571428, with a leftover of 8e-09.
