We're dividing 683447 by 426 
The aim is to understand the frequency of 426 in 683447.

Step 1:
426 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 426

Let's proceed to step 2:
426 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 426

Step 3:
683 divided by 426 is 1 with a remainder of 257.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 426 from 683, we get 257.
Include the next digit (4) from the dividend after 257, then repeat: 2574 / 426

Going ahead to step 4:
If we divide 2574 by 426, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2556 from 2574 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 426

Let's proceed to step 5:
426 can be fit into 184 0 times, resulting in a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 160.0
The remainder is 184 after subtracting 0 from 184.
Grab the next digit (7) from the dividend, add it to 184, then carry on: 1847 / 426

Advancing to step 6:
When dividing 1847 by 426, we get 4 with a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 1604.0
The remainder is 143 after subtracting 1704 from 1847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 7:
If we divide 1430 by 426, we get 3 and a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 1604.3
The remainder is 152 after subtracting 1278 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 8:
426 can be fit into 1520 3 times, resulting in a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 1604.33
Subtracting 1278 from 1520 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final result is 1604.33 with a remainder of 0.242.
