Let's divide 71977516 by 343
The aim is to understand the frequency of 343 in 71977516.

Step 1:
7 divided by 343 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 343

Going ahead to step 2:
71 divided by 343 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 343

Moving on to step 3:
343 can be fit into 719 2 times, resulting in a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 686 from 719 leaves us with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 343

Going ahead to step 4:
343 goes into 337 0 times with a remainder of 337.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 337 and we're left with 337.
Append the next digit (7) from the dividend to 337 and continue with: 3377 / 343

On to step 5:
If we divide 3377 by 343, we get 9 and a remainder of 290.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Deduct 3087 from 3377 and we're left with 290.
Take the next digit (5) from the dividend and append it to 290, then repeat: 2905 / 343

Going ahead to step 6:
The number 343 fits into 2905 8 times, leaving a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 2098.0
If we subtract 2744 from 2905, we get 161.
Fetch the next digit (1) from the dividend, attach it to 161 and continue: 1611 / 343

On to step 7:
343 can be fit into 1611 4 times, resulting in a remainder of 239.
Write down 4 as next digit of the result. 
Result so far: 20984.0
The remainder is 239 after subtracting 1372 from 1611.
Take the next digit (6) from the dividend and append it to 239, then repeat: 2396 / 343

Step 8:
2396 divided by 343 is 6 with a remainder of 338.
The next digit of our result is 6. 
Result so far: 209846.0
Subtracting 2058 from 2396 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 9:
3380 divided by 343 is 9 with a remainder of 293.
Record the quotient 9 as the next digit in the result. 
Result so far: 209846.9
The remainder is 293 after subtracting 3087 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 10:
When dividing 2930 by 343, we get 8 with a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 209846.98
If we take 2744 away from 2930, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 11:
343 goes into 1860 5 times with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 209846.985
Subtracting 1715 from 1860 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 12:
The number 343 fits into 1450 4 times, leaving a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 209846.9854
Deduct 1372 from 1450 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 13:
780 divided by 343 is 2 with a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 209846.98542
Subtract 686 from 780 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 14:
343 can be fit into 940 2 times, resulting in a remainder of 254.
Write down 2 as next digit of the result. 
Result so far: 209846.985422
Subtracting 686 from 940 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The quotient of the division is 209846.985422, and the remainder is 2.54e-05.
