389523 divided by 74 
The aim is to understand the frequency of 74 in 389523.

Going ahead to step 1:
3 divided by 74 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 74

Let's proceed to step 2:
38 divided by 74 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 74

On to step 3:
When dividing 389 by 74, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 370 from 389 and we're left with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 74

Advancing to step 4:
The number 74 fits into 195 2 times, leaving a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 148 away from 195, we end up with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 74

Moving on to step 5:
74 goes into 472 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 526.0
If we subtract 444 from 472, we get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 74

Advancing to step 6:
If we divide 283 by 74, we get 3 and a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 5263.0
Subtracting 222 from 283 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
The number 74 fits into 610 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 5263.8
If we take 592 away from 610, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 74, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 5263.82
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
The number 74 fits into 320 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 5263.824
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
74 can be fit into 240 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 5263.8243
Subtract 222 from 240 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 74 fits into 180 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 5263.82432
Deduct 148 from 180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 74 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 5263.824324
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 74 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 5263.8243243
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
180 divided by 74 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 5263.82432432
If we subtract 148 from 180, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 5263.82432432, with a leftover of 3.2e-08.
