Let's divide 64201604 by 941
The aim is to understand the frequency of 941 in 64201604.

On to step 1:
The number 941 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 941

Step 2:
941 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 941

Going ahead to step 3:
When dividing 642 by 941, we get 0 with a remainder of 642.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 642 leaves us with 642.
Append the next digit (0) from the dividend to 642 and continue with: 6420 / 941

On to step 4:
941 can be fit into 6420 6 times, resulting in a remainder of 774.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5646 from 6420 to get 774.
Include the next digit (1) from the dividend after 774, then repeat: 7741 / 941

Going ahead to step 5:
The number 941 fits into 7741 8 times, leaving a remainder of 213.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 7528 from 7741 leaves us with 213.
Append the next digit (6) from the dividend to 213 and continue with: 2136 / 941

Moving on to step 6:
2136 divided by 941 is 2 with a remainder of 254.
Write down 2 as next digit of the result. 
Result so far: 682.0
The remainder is 254 after subtracting 1882 from 2136.
Append the next digit (0) from the dividend to 254 and continue with: 2540 / 941

Step 7:
941 goes into 2540 2 times with a remainder of 658.
Use 2 as the next digit of our solution. 
Result so far: 6822.0
The remainder is 658 after subtracting 1882 from 2540.
Take the next digit (4) from the dividend and append it to 658, then repeat: 6584 / 941

Going ahead to step 8:
6584 divided by 941 is 6 with a remainder of 938.
The next digit of our result is 6. 
Result so far: 68226.0
If we take 5646 away from 6584, we end up with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

On to step 9:
9380 divided by 941 is 9 with a remainder of 911.
Record the quotient 9 as the next digit in the result. 
Result so far: 68226.9
If we subtract 8469 from 9380, we get 911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9110, and continue the process.

Advancing to step 10:
If we divide 9110 by 941, we get 9 and a remainder of 641.
Put 9 as the next digit of the answer. 
Result so far: 68226.99
Subtracting 8469 from 9110 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

The final result is 68226.99 with a remainder of 0.641.
