Let's divide 72174284 by 349
The aim is to understand the frequency of 349 in 72174284.

Moving on to step 1:
When dividing 7 by 349, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 349

Moving on to step 2:
72 divided by 349 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 349

On to step 3:
The number 349 fits into 721 2 times, leaving a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 698 from 721 and we're left with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 349

On to step 4:
If we divide 237 by 349, we get 0 and a remainder of 237.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 237 after subtracting 0 from 237.
Bring next digit (4) of the dividend behind the 237 and repeat the process: 2374 / 349

Step 5:
2374 divided by 349 is 6 with a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtracting 2094 from 2374 leaves us with 280.
Include the next digit (2) from the dividend after 280, then repeat: 2802 / 349

On to step 6:
When dividing 2802 by 349, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 2068.0
The remainder is 10 after subtracting 2792 from 2802.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 349

Moving on to step 7:
If we divide 108 by 349, we get 0 and a remainder of 108.
Put 0 as the next digit of the answer. 
Result so far: 20680.0
Deduct 0 from 108 and we're left with 108.
Bring next digit (4) of the dividend behind the 108 and repeat the process: 1084 / 349

Let's proceed to step 8:
When dividing 1084 by 349, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 206803.0
Deduct 1047 from 1084 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
349 goes into 370 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 206803.1
If we subtract 349 from 370, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
349 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 206803.1
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 11:
When dividing 2100 by 349, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 206803.106
Subtracting 2094 from 2100 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
60 divided by 349 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 206803.106
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
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: 206803.10601
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.

Step 14:
349 can be fit into 2510 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 206803.106017
If we subtract 2443 from 2510, we get 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 15:
The number 349 fits into 670 1 times, leaving a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 206803.1060171
If we subtract 349 from 670, we 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.

Let's proceed to step 16:
3210 divided by 349 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 206803.10601719
Subtracting 3141 from 3210 leaves us 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.

The final outcome is 206803.10601719, with a leftover of 6.9e-08.
