We divide 98577881 by 343
The aim is to understand the frequency of 343 in 98577881.

Going ahead to step 1:
343 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 343

Let's proceed to step 2:
98 divided by 343 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 343

Let's proceed to step 3:
When dividing 985 by 343, we get 2 with a remainder of 299.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 299 after subtracting 686 from 985.
Append the next digit (7) from the dividend to 299 and continue with: 2997 / 343

Step 4:
If we divide 2997 by 343, we get 8 and a remainder of 253.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 253 after subtracting 2744 from 2997.
Fetch the next digit (7) from the dividend, attach it to 253 and continue: 2537 / 343

On to step 5:
When dividing 2537 by 343, we get 7 with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 287.0
If we take 2401 away from 2537, we end up with 136.
Take the next digit (8) from the dividend and append it to 136, then repeat: 1368 / 343

Advancing to step 6:
1368 divided by 343 is 3 with a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 2873.0
If we take 1029 away from 1368, we end up with 339.
Bring next digit (8) of the dividend behind the 339 and repeat the process: 3398 / 343

On to step 7:
343 can be fit into 3398 9 times, resulting in a remainder of 311.
Put 9 as the next digit of the answer. 
Result so far: 28739.0
Subtract 3087 from 3398 to get 311.
Grab the next digit (1) from the dividend, add it to 311, then carry on: 3111 / 343

Step 8:
If we divide 3111 by 343, we get 9 and a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 287399.0
If we take 3087 away from 3111, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 343, we get 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 287399.0
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
343 can be fit into 2400 6 times, resulting in a remainder of 342.
The next digit of our result is 6. 
Result so far: 287399.06
Subtracting 2058 from 2400 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 11:
If we divide 3420 by 343, we get 9 and a remainder of 333.
The number 9 becomes the next digit in our result. 
Result so far: 287399.069
The remainder is 333 after subtracting 3087 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 12:
If we divide 3330 by 343, we get 9 and a remainder of 243.
Record the quotient 9 as the next digit in the result. 
Result so far: 287399.0699
If we take 3087 away from 3330, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Our division results in 287399.0699 with a remaining 0.00243.
