94907924 ÷ 644 
The aim is to understand the frequency of 644 in 94907924.

Moving on to step 1:
644 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 644

Advancing to step 2:
644 goes into 94 0 times with a remainder of 94.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 94, we get 94.
Append the next digit (9) from the dividend to 94 and continue with: 949 / 644

Moving on to step 3:
644 can be fit into 949 1 times, resulting in a remainder of 305.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 644 from 949, we get 305.
Bring next digit (0) of the dividend behind the 305 and repeat the process: 3050 / 644

Let's proceed to step 4:
The number 644 fits into 3050 4 times, leaving a remainder of 474.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2576 from 3050, we get 474.
Take the next digit (7) from the dividend and append it to 474, then repeat: 4747 / 644

Going ahead to step 5:
The number 644 fits into 4747 7 times, leaving a remainder of 239.
Write down 7 as next digit of the result. 
Result so far: 147.0
If we subtract 4508 from 4747, we get 239.
Fetch the next digit (9) from the dividend, attach it to 239 and continue: 2399 / 644

Let's proceed to step 6:
2399 divided by 644 is 3 with a remainder of 467.
The number 3 becomes the next digit in our result. 
Result so far: 1473.0
If we take 1932 away from 2399, we end up with 467.
Bring next digit (2) of the dividend behind the 467 and repeat the process: 4672 / 644

Advancing to step 7:
If we divide 4672 by 644, we get 7 and a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 14737.0
The remainder is 164 after subtracting 4508 from 4672.
Append the next digit (4) from the dividend to 164 and continue with: 1644 / 644

Let's proceed to step 8:
The number 644 fits into 1644 2 times, leaving a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 147372.0
If we take 1288 away from 1644, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 9:
644 can be fit into 3560 5 times, resulting in a remainder of 340.
The next digit of our result is 5. 
Result so far: 147372.5
Subtract 3220 from 3560 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
If we divide 3400 by 644, we get 5 and a remainder of 180.
The next digit of our result is 5. 
Result so far: 147372.55
The remainder is 180 after subtracting 3220 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 147372.55, and the remainder is 0.18.
