Let's divide 45338768 by 390
The aim is to understand the frequency of 390 in 45338768.

Moving on to step 1:
When dividing 4 by 390, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 390

Let's proceed to step 2:
390 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 390

Let's proceed to step 3:
When dividing 453 by 390, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 390 from 453 leaves us with 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 390

Step 4:
If we divide 633 by 390, we get 1 and a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 390 from 633, we get 243.
Grab the next digit (8) from the dividend, add it to 243, then carry on: 2438 / 390

Advancing to step 5:
The number 390 fits into 2438 6 times, leaving a remainder of 98.
The next digit of our result is 6. 
Result so far: 116.0
Subtracting 2340 from 2438 leaves us with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 390

Let's proceed to step 6:
390 goes into 987 2 times with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 1162.0
Subtract 780 from 987 to get 207.
Fetch the next digit (6) from the dividend, attach it to 207 and continue: 2076 / 390

Let's proceed to step 7:
2076 divided by 390 is 5 with a remainder of 126.
The next digit of our result is 5. 
Result so far: 11625.0
Subtract 1950 from 2076 to get 126.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 390

Step 8:
390 can be fit into 1268 3 times, resulting in a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 116253.0
Subtracting 1170 from 1268 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
390 can be fit into 980 2 times, resulting in a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 116253.2
The remainder is 200 after subtracting 780 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
2000 divided by 390 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 116253.25
If we take 1950 away from 2000, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
390 can be fit into 500 1 times, resulting in a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 116253.251
If we take 390 away from 500, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
390 goes into 1100 2 times with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 116253.2512
Deduct 780 from 1100 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
If we divide 3200 by 390, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 116253.25128
Deduct 3120 from 3200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
800 divided by 390 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 116253.251282
If we take 780 away from 800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
390 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 116253.251282
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
390 can be fit into 2000 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 116253.25128205
Subtract 1950 from 2000 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 116253.25128205, and the remainder is 5e-08.
