4204574 divided by 320 
The aim is to understand the frequency of 320 in 4204574.

On to step 1:
320 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 320

Going ahead to step 2:
320 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 320

Let's proceed to step 3:
If we divide 420 by 320, we get 1 and a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 320 from 420, we get 100.
Fetch the next digit (4) from the dividend, attach it to 100 and continue: 1004 / 320

Let's proceed to step 4:
320 can be fit into 1004 3 times, resulting in a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 44 after subtracting 960 from 1004.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 320

Let's proceed to step 5:
445 divided by 320 is 1 with a remainder of 125.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 320 from 445 and we're left with 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 320

Step 6:
The number 320 fits into 1257 3 times, leaving a remainder of 297.
Put 3 as the next digit of the answer. 
Result so far: 1313.0
If we take 960 away from 1257, we end up with 297.
Fetch the next digit (4) from the dividend, attach it to 297 and continue: 2974 / 320

Advancing to step 7:
2974 divided by 320 is 9 with a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 13139.0
The remainder is 94 after subtracting 2880 from 2974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 8:
320 can be fit into 940 2 times, resulting in a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 13139.2
Deduct 640 from 940 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 9:
If we divide 3000 by 320, we get 9 and a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 13139.29
Subtract 2880 from 3000 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
320 goes into 1200 3 times with a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 13139.293
Subtract 960 from 1200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
2400 divided by 320 is 7 with a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 13139.2937
If we take 2240 away from 2400, 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.

Advancing to step 12:
When dividing 1600 by 320, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13139.29375
Subtracting 1600 from 1600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
When dividing 0 by 320, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13139.29375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
If we divide 0 by 320, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13139.29375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 13139.29375, with a leftover of 0.0.
