Let's divide 21274771 by 601
The aim is to understand the frequency of 601 in 21274771.

On to step 1:
2 divided by 601 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 601

Advancing to step 2:
601 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 601

Let's proceed to step 3:
601 can be fit into 212 0 times, resulting in a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 601

Advancing to step 4:
601 goes into 2127 3 times with a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1803 from 2127, we get 324.
Append the next digit (4) from the dividend to 324 and continue with: 3244 / 601

Advancing to step 5:
601 can be fit into 3244 5 times, resulting in a remainder of 239.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 3005 from 3244 to get 239.
Grab the next digit (7) from the dividend, add it to 239, then carry on: 2397 / 601

Step 6:
2397 divided by 601 is 3 with a remainder of 594.
The next digit of our result is 3. 
Result so far: 353.0
Subtracting 1803 from 2397 leaves us with 594.
Grab the next digit (7) from the dividend, add it to 594, then carry on: 5947 / 601

On to step 7:
5947 divided by 601 is 9 with a remainder of 538.
The number 9 becomes the next digit in our result. 
Result so far: 3539.0
If we subtract 5409 from 5947, we get 538.
Append the next digit (1) from the dividend to 538 and continue with: 5381 / 601

Let's proceed to step 8:
601 goes into 5381 8 times with a remainder of 573.
Put 8 as the next digit of the answer. 
Result so far: 35398.0
Subtracting 4808 from 5381 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 9:
601 can be fit into 5730 9 times, resulting in a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 35398.9
Subtract 5409 from 5730 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 10:
When dividing 3210 by 601, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 35398.95
The remainder is 205 after subtracting 3005 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 11:
If we divide 2050 by 601, we get 3 and a remainder of 247.
Use 3 as the next digit of our solution. 
Result so far: 35398.953
Deduct 1803 from 2050 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 12:
601 goes into 2470 4 times with a remainder of 66.
The next digit of our result is 4. 
Result so far: 35398.9534
The remainder is 66 after subtracting 2404 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
The number 601 fits into 660 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 35398.95341
Deduct 601 from 660 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
601 can be fit into 590 0 times, resulting in a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 35398.95341
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 15:
601 goes into 5900 9 times with a remainder of 491.
Put 9 as the next digit of the answer. 
Result so far: 35398.9534109
Subtracting 5409 from 5900 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 16:
601 goes into 4910 8 times with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 35398.95341098
Subtract 4808 from 4910 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

In conclusion, the division gives 35398.95341098 with a balance of 1.02e-07.
