Let's divide 1398075 by 320
The aim is to understand the frequency of 320 in 1398075.

Let's proceed to step 1:
The number 320 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 320

Let's proceed to step 2:
The number 320 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 320

Let's proceed to step 3:
320 goes into 139 0 times with a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 320

Let's proceed to step 4:
1398 divided by 320 is 4 with a remainder of 118.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1280 from 1398, we get 118.
Fetch the next digit (0) from the dividend, attach it to 118 and continue: 1180 / 320

Let's proceed to step 5:
If we divide 1180 by 320, we get 3 and a remainder of 220.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 960 from 1180 leaves us with 220.
Grab the next digit (7) from the dividend, add it to 220, then carry on: 2207 / 320

Advancing to step 6:
The number 320 fits into 2207 6 times, leaving a remainder of 287.
The next digit of our result is 6. 
Result so far: 436.0
Subtracting 1920 from 2207 leaves us with 287.
Take the next digit (5) from the dividend and append it to 287, then repeat: 2875 / 320

Going ahead to step 7:
If we divide 2875 by 320, we get 8 and a remainder of 315.
The next digit of our result is 8. 
Result so far: 4368.0
Deduct 2560 from 2875 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 8:
320 goes into 3150 9 times with a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 4368.9
If we subtract 2880 from 3150, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
When dividing 2700 by 320, we get 8 with a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 4368.98
Subtracting 2560 from 2700 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
When dividing 1400 by 320, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 4368.984
Deduct 1280 from 1400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
When dividing 1200 by 320, we get 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 4368.9843
If we take 960 away from 1200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
2400 divided by 320 is 7 with a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 4368.98437
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4368.984375
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.

Moving on to step 14:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4368.984375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
If we divide 0 by 320, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4368.984375
Subtract 0 from 0 to get 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 result is 4368.984375 with a remainder of 0.0.
