Let's divide 17389444 by 672
The aim is to understand the frequency of 672 in 17389444.

On to step 1:
The number 672 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 672

Let's proceed to step 2:
672 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 672

Going ahead to step 3:
When dividing 173 by 672, we get 0 with a remainder of 173.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 672

Going ahead to step 4:
If we divide 1738 by 672, we get 2 and a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1344 from 1738 and we're left with 394.
Fetch the next digit (9) from the dividend, attach it to 394 and continue: 3949 / 672

Moving on to step 5:
When dividing 3949 by 672, we get 5 with a remainder of 589.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 3360 from 3949 to get 589.
Append the next digit (4) from the dividend to 589 and continue with: 5894 / 672

Step 6:
5894 divided by 672 is 8 with a remainder of 518.
Put 8 as the next digit of the answer. 
Result so far: 258.0
The remainder is 518 after subtracting 5376 from 5894.
Append the next digit (4) from the dividend to 518 and continue with: 5184 / 672

Going ahead to step 7:
5184 divided by 672 is 7 with a remainder of 480.
Write down 7 as next digit of the result. 
Result so far: 2587.0
If we subtract 4704 from 5184, we get 480.
Take the next digit (4) from the dividend and append it to 480, then repeat: 4804 / 672

Let's proceed to step 8:
4804 divided by 672 is 7 with a remainder of 100.
Write down 7 as next digit of the result. 
Result so far: 25877.0
The remainder is 100 after subtracting 4704 from 4804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 9:
When dividing 1000 by 672, we get 1 with a remainder of 328.
Use 1 as the next digit of our solution. 
Result so far: 25877.1
Deduct 672 from 1000 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 10:
If we divide 3280 by 672, we get 4 and a remainder of 592.
Record the quotient 4 as the next digit in the result. 
Result so far: 25877.14
The remainder is 592 after subtracting 2688 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 11:
5920 divided by 672 is 8 with a remainder of 544.
The next digit of our result is 8. 
Result so far: 25877.148
The remainder is 544 after subtracting 5376 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
5440 divided by 672 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 25877.1488
If we take 5376 away from 5440, 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.

After the division, we end up with 25877.1488 and a remainder of 0.00064.
