73186350 divided by 343 
The aim is to understand the frequency of 343 in 73186350.

Going ahead to step 1:
343 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 343

Step 2:
When dividing 73 by 343, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 343

On to step 3:
343 goes into 731 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 686 from 731, we get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 343

Advancing to step 4:
When dividing 458 by 343, we get 1 with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 343 from 458 leaves us with 115.
Include the next digit (6) from the dividend after 115, then repeat: 1156 / 343

Going ahead to step 5:
The number 343 fits into 1156 3 times, leaving a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtract 1029 from 1156 to get 127.
Bring next digit (3) of the dividend behind the 127 and repeat the process: 1273 / 343

On to step 6:
343 goes into 1273 3 times with a remainder of 244.
The next digit of our result is 3. 
Result so far: 2133.0
If we take 1029 away from 1273, we end up with 244.
Bring next digit (5) of the dividend behind the 244 and repeat the process: 2445 / 343

Moving on to step 7:
If we divide 2445 by 343, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 21337.0
Subtract 2401 from 2445 to get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 343

Let's proceed to step 8:
When dividing 440 by 343, we get 1 with a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 213371.0
Subtract 343 from 440 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
If we divide 970 by 343, we get 2 and a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 213371.2
The remainder is 284 after subtracting 686 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 10:
The number 343 fits into 2840 8 times, leaving a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 213371.28
Deduct 2744 from 2840 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
The number 343 fits into 960 2 times, leaving a remainder of 274.
The next digit of our result is 2. 
Result so far: 213371.282
If we subtract 686 from 960, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 12:
The number 343 fits into 2740 7 times, leaving a remainder of 339.
Write down 7 as next digit of the result. 
Result so far: 213371.2827
Subtracting 2401 from 2740 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 13:
When dividing 3390 by 343, we get 9 with a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 213371.28279
If we take 3087 away from 3390, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 14:
3030 divided by 343 is 8 with a remainder of 286.
The number 8 becomes the next digit in our result. 
Result so far: 213371.282798
The remainder is 286 after subtracting 2744 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 15:
343 goes into 2860 8 times with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 213371.2827988
If we take 2744 away from 2860, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 213371.2827988, and the remainder is 1.16e-06.
