Let's divide 353645 by 74
The aim is to understand the frequency of 74 in 353645.

Moving on to step 1:
The number 74 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 74

Moving on to step 2:
If we divide 35 by 74, we get 0 and a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 74

Going ahead to step 3:
When dividing 353 by 74, we get 4 with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 296 away from 353, we end up with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 74

Step 4:
The number 74 fits into 576 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 518 from 576 and we're left with 58.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 74

Advancing to step 5:
74 can be fit into 584 7 times, resulting in a remainder of 66.
The next digit of our result is 7. 
Result so far: 477.0
If we subtract 518 from 584, we get 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 74

Moving on to step 6:
665 divided by 74 is 8 with a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 4778.0
Deduct 592 from 665 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
74 can be fit into 730 9 times, resulting in a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 4778.9
Subtracting 666 from 730 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
640 divided by 74 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 4778.98
The remainder is 48 after subtracting 592 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
When dividing 480 by 74, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 4778.986
If we subtract 444 from 480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
If we divide 360 by 74, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 4778.9864
Subtracting 296 from 360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
If we divide 640 by 74, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4778.98648
If we take 592 away from 640, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 74 fits into 480 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 4778.986486
The remainder is 36 after subtracting 444 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
The number 74 fits into 360 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 4778.9864864
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
640 divided by 74 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4778.98648648
Subtract 592 from 640 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 4778.98648648 and a remainder of 4.8e-08.
