We look at the division of 52631005 by 349 
The aim is to understand the frequency of 349 in 52631005.

Step 1:
5 divided by 349 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 349

Moving on to step 2:
The number 349 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 349

Moving on to step 3:
349 can be fit into 526 1 times, resulting in a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 349 from 526, we get 177.
Grab the next digit (3) from the dividend, add it to 177, then carry on: 1773 / 349

Going ahead to step 4:
The number 349 fits into 1773 5 times, leaving a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1745 from 1773, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 349

Step 5:
When dividing 281 by 349, we get 0 with a remainder of 281.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we subtract 0 from 281, we get 281.
Append the next digit (0) from the dividend to 281 and continue with: 2810 / 349

Step 6:
349 goes into 2810 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1508.0
Subtracting 2792 from 2810 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 349

Step 7:
When dividing 180 by 349, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 15080.0
Subtract 0 from 180 to get 180.
Include the next digit (5) from the dividend after 180, then repeat: 1805 / 349

Moving on to step 8:
349 goes into 1805 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 150805.0
The remainder is 60 after subtracting 1745 from 1805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 349 fits into 600 1 times, leaving a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 150805.1
If we take 349 away from 600, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 10:
When dividing 2510 by 349, we get 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 150805.17
Subtracting 2443 from 2510 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
349 goes into 670 1 times with a remainder of 321.
Record the quotient 1 as the next digit in the result. 
Result so far: 150805.171
The remainder is 321 after subtracting 349 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 12:
When dividing 3210 by 349, we get 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 150805.1719
If we subtract 3141 from 3210, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 13:
When dividing 690 by 349, we get 1 with a remainder of 341.
Put 1 as the next digit of the answer. 
Result so far: 150805.17191
If we subtract 349 from 690, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
349 can be fit into 3410 9 times, resulting in a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 150805.171919
If we take 3141 away from 3410, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 15:
2690 divided by 349 is 7 with a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 150805.1719197
If we take 2443 away from 2690, we end up 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.

Going ahead to step 16:
When dividing 2470 by 349, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 150805.17191977
Deduct 2443 from 2470 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 150805.17191977 and a remainder of 2.7e-08.
