We look at the division of 6595702 by 423 
The aim is to understand the frequency of 423 in 6595702.

On to step 1:
The number 423 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 423

Step 2:
423 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 423

Step 3:
423 can be fit into 659 1 times, resulting in a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 423 away from 659, we end up with 236.
Fetch the next digit (5) from the dividend, attach it to 236 and continue: 2365 / 423

Step 4:
When dividing 2365 by 423, we get 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2115 from 2365 to get 250.
Append the next digit (7) from the dividend to 250 and continue with: 2507 / 423

Step 5:
The number 423 fits into 2507 5 times, leaving a remainder of 392.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 2115 from 2507 to get 392.
Fetch the next digit (0) from the dividend, attach it to 392 and continue: 3920 / 423

On to step 6:
When dividing 3920 by 423, we get 9 with a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 1559.0
If we take 3807 away from 3920, we end up with 113.
Take the next digit (2) from the dividend and append it to 113, then repeat: 1132 / 423

Moving on to step 7:
If we divide 1132 by 423, we get 2 and a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 15592.0
Subtracting 846 from 1132 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 8:
The number 423 fits into 2860 6 times, leaving a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 15592.6
Deduct 2538 from 2860 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
If we divide 3220 by 423, we get 7 and a remainder of 259.
The number 7 becomes the next digit in our result. 
Result so far: 15592.67
Subtracting 2961 from 3220 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 10:
If we divide 2590 by 423, we get 6 and a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 15592.676
Deduct 2538 from 2590 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
423 goes into 520 1 times with a remainder of 97.
The next digit of our result is 1. 
Result so far: 15592.6761
If we subtract 423 from 520, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 12:
The number 423 fits into 970 2 times, leaving a remainder of 124.
The next digit of our result is 2. 
Result so far: 15592.67612
Deduct 846 from 970 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 13:
When dividing 1240 by 423, we get 2 with a remainder of 394.
Record the quotient 2 as the next digit in the result. 
Result so far: 15592.676122
If we take 846 away from 1240, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

After the division, we end up with 15592.676122 and a remainder of 3.94e-05.
