We look at the division of 14221689 by 597 
The aim is to understand the frequency of 597 in 14221689.

On to step 1:
If we divide 1 by 597, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 597

Let's proceed to step 2:
If we divide 14 by 597, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 597

Let's proceed to step 3:
597 can be fit into 142 0 times, resulting in a remainder of 142.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 142 leaves us with 142.
Include the next digit (2) from the dividend after 142, then repeat: 1422 / 597

Moving on to step 4:
If we divide 1422 by 597, we get 2 and a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1194 from 1422 leaves us with 228.
Fetch the next digit (1) from the dividend, attach it to 228 and continue: 2281 / 597

On to step 5:
When dividing 2281 by 597, we get 3 with a remainder of 490.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 1791 from 2281 and we're left with 490.
Fetch the next digit (6) from the dividend, attach it to 490 and continue: 4906 / 597

Advancing to step 6:
4906 divided by 597 is 8 with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
If we take 4776 away from 4906, we end up with 130.
Grab the next digit (8) from the dividend, add it to 130, then carry on: 1308 / 597

Going ahead to step 7:
597 can be fit into 1308 2 times, resulting in a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 2382.0
The remainder is 114 after subtracting 1194 from 1308.
Include the next digit (9) from the dividend after 114, then repeat: 1149 / 597

On to step 8:
When dividing 1149 by 597, we get 1 with a remainder of 552.
Record the quotient 1 as the next digit in the result. 
Result so far: 23821.0
Subtract 597 from 1149 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 9:
597 can be fit into 5520 9 times, resulting in a remainder of 147.
The next digit of our result is 9. 
Result so far: 23821.9
If we take 5373 away from 5520, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 10:
If we divide 1470 by 597, we get 2 and a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 23821.92
Subtracting 1194 from 1470 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
If we divide 2760 by 597, we get 4 and a remainder of 372.
Write down 4 as next digit of the result. 
Result so far: 23821.924
Subtracting 2388 from 2760 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 12:
597 goes into 3720 6 times with a remainder of 138.
Write down 6 as next digit of the result. 
Result so far: 23821.9246
Subtract 3582 from 3720 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 13:
The number 597 fits into 1380 2 times, leaving a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 23821.92462
If we subtract 1194 from 1380, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 14:
When dividing 1860 by 597, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 23821.924623
Deduct 1791 from 1860 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 15:
690 divided by 597 is 1 with a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 23821.9246231
If we subtract 597 from 690, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 16:
597 can be fit into 930 1 times, resulting in a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 23821.92462311
Deduct 597 from 930 and we're left with 333.
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 23821.92462311 with a remainder of 3.33e-07.
