We're dividing 51440842 by 601 
The aim is to understand the frequency of 601 in 51440842.

Let's proceed to step 1:
The number 601 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 601

Going ahead to step 2:
51 divided by 601 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 601

Advancing to step 3:
The number 601 fits into 514 0 times, leaving a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 514, we end up with 514.
Bring next digit (4) of the dividend behind the 514 and repeat the process: 5144 / 601

Step 4:
When dividing 5144 by 601, we get 8 with a remainder of 336.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 4808 from 5144, we get 336.
Fetch the next digit (0) from the dividend, attach it to 336 and continue: 3360 / 601

On to step 5:
601 can be fit into 3360 5 times, resulting in a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 3005 from 3360 to get 355.
Bring next digit (8) of the dividend behind the 355 and repeat the process: 3558 / 601

On to step 6:
When dividing 3558 by 601, we get 5 with a remainder of 553.
The next digit of our result is 5. 
Result so far: 855.0
The remainder is 553 after subtracting 3005 from 3558.
Fetch the next digit (4) from the dividend, attach it to 553 and continue: 5534 / 601

Let's proceed to step 7:
When dividing 5534 by 601, we get 9 with a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 8559.0
If we take 5409 away from 5534, we end up with 125.
Take the next digit (2) from the dividend and append it to 125, then repeat: 1252 / 601

Moving on to step 8:
If we divide 1252 by 601, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 85592.0
Subtracting 1202 from 1252 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 601 fits into 500 0 times, leaving a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 85592.0
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
601 goes into 5000 8 times with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 85592.08
Deduct 4808 from 5000 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
601 goes into 1920 3 times with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 85592.083
Deduct 1803 from 1920 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 12:
If we divide 1170 by 601, we get 1 and a remainder of 569.
Record the quotient 1 as the next digit in the result. 
Result so far: 85592.0831
The remainder is 569 after subtracting 601 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 13:
5690 divided by 601 is 9 with a remainder of 281.
Use 9 as the next digit of our solution. 
Result so far: 85592.08319
Subtract 5409 from 5690 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 14:
601 can be fit into 2810 4 times, resulting in a remainder of 406.
The next digit of our result is 4. 
Result so far: 85592.083194
Subtracting 2404 from 2810 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 15:
4060 divided by 601 is 6 with a remainder of 454.
The next digit of our result is 6. 
Result so far: 85592.0831946
Subtracting 3606 from 4060 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 16:
When dividing 4540 by 601, we get 7 with a remainder of 333.
Put 7 as the next digit of the answer. 
Result so far: 85592.08319467
The remainder is 333 after subtracting 4207 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

The final result is 85592.08319467 with a remainder of 3.33e-07.
