52640743 divided by 349 
The aim is to understand the frequency of 349 in 52640743.

Going ahead to step 1:
When dividing 5 by 349, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 349

Let's proceed to step 2:
349 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 349

Step 3:
349 can be fit into 526 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 349 from 526 and we're left with 177.
Take the next digit (4) from the dividend and append it to 177, then repeat: 1774 / 349

Going ahead to step 4:
349 can be fit into 1774 5 times, resulting in a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 1745 from 1774 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 349

Moving on to step 5:
When dividing 290 by 349, we get 0 with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we take 0 away from 290, we end up with 290.
Append the next digit (7) from the dividend to 290 and continue with: 2907 / 349

On to step 6:
349 goes into 2907 8 times with a remainder of 115.
Put 8 as the next digit of the answer. 
Result so far: 1508.0
The remainder is 115 after subtracting 2792 from 2907.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 349

Advancing to step 7:
When dividing 1154 by 349, we get 3 with a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 15083.0
If we subtract 1047 from 1154, we get 107.
Fetch the next digit (3) from the dividend, attach it to 107 and continue: 1073 / 349

Going ahead to step 8:
349 goes into 1073 3 times with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 150833.0
If we take 1047 away from 1073, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
260 divided by 349 is 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 150833.0
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
When dividing 2600 by 349, we get 7 with a remainder of 157.
Write down 7 as next digit of the result. 
Result so far: 150833.07
If we take 2443 away from 2600, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 11:
When dividing 1570 by 349, we get 4 with a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 150833.074
Subtract 1396 from 1570 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 12:
The number 349 fits into 1740 4 times, leaving a remainder of 344.
Use 4 as the next digit of our solution. 
Result so far: 150833.0744
Subtracting 1396 from 1740 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final result is 150833.0744 with a remainder of 0.00344.
