We look at the division of 64243354 by 601 
The aim is to understand the frequency of 601 in 64243354.

Moving on to step 1:
6 divided by 601 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 601

On to step 2:
64 divided by 601 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 601

Moving on to step 3:
The number 601 fits into 642 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 601 away from 642, we end up with 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 601

Advancing to step 4:
The number 601 fits into 414 0 times, leaving a remainder of 414.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 414 and we're left with 414.
Bring next digit (3) of the dividend behind the 414 and repeat the process: 4143 / 601

Going ahead to step 5:
When dividing 4143 by 601, we get 6 with a remainder of 537.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 537 after subtracting 3606 from 4143.
Take the next digit (3) from the dividend and append it to 537, then repeat: 5373 / 601

Going ahead to step 6:
601 goes into 5373 8 times with a remainder of 565.
The number 8 becomes the next digit in our result. 
Result so far: 1068.0
If we take 4808 away from 5373, we end up with 565.
Fetch the next digit (5) from the dividend, attach it to 565 and continue: 5655 / 601

Moving on to step 7:
601 can be fit into 5655 9 times, resulting in a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 10689.0
Deduct 5409 from 5655 and we're left with 246.
Include the next digit (4) from the dividend after 246, then repeat: 2464 / 601

Let's proceed to step 8:
When dividing 2464 by 601, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 106894.0
Subtract 2404 from 2464 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 601, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 106894.0
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 10:
6000 divided by 601 is 9 with a remainder of 591.
Use 9 as the next digit of our solution. 
Result so far: 106894.09
If we subtract 5409 from 6000, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 11:
If we divide 5910 by 601, we get 9 and a remainder of 501.
Put 9 as the next digit of the answer. 
Result so far: 106894.099
If we take 5409 away from 5910, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

The final outcome is 106894.099, with a leftover of 0.0501.
