29687786 divided by 343 
The aim is to understand the frequency of 343 in 29687786.

Step 1:
If we divide 2 by 343, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 343

Going ahead to step 2:
29 divided by 343 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 343

Going ahead to step 3:
343 goes into 296 0 times with a remainder of 296.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 296 after subtracting 0 from 296.
Grab the next digit (8) from the dividend, add it to 296, then carry on: 2968 / 343

Step 4:
When dividing 2968 by 343, we get 8 with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 2744 from 2968 and we're left with 224.
Append the next digit (7) from the dividend to 224 and continue with: 2247 / 343

Moving on to step 5:
When dividing 2247 by 343, we get 6 with a remainder of 189.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 189 after subtracting 2058 from 2247.
Fetch the next digit (7) from the dividend, attach it to 189 and continue: 1897 / 343

Moving on to step 6:
343 goes into 1897 5 times with a remainder of 182.
Write down 5 as next digit of the result. 
Result so far: 865.0
Subtract 1715 from 1897 to get 182.
Grab the next digit (8) from the dividend, add it to 182, then carry on: 1828 / 343

Moving on to step 7:
343 can be fit into 1828 5 times, resulting in a remainder of 113.
Write down 5 as next digit of the result. 
Result so far: 8655.0
If we subtract 1715 from 1828, we get 113.
Grab the next digit (6) from the dividend, add it to 113, then carry on: 1136 / 343

Advancing to step 8:
If we divide 1136 by 343, we get 3 and a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 86553.0
If we take 1029 away from 1136, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
343 goes into 1070 3 times with a remainder of 41.
The next digit of our result is 3. 
Result so far: 86553.3
The remainder is 41 after subtracting 1029 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
If we divide 410 by 343, we get 1 and a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 86553.31
If we take 343 away from 410, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
670 divided by 343 is 1 with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 86553.311
Deduct 343 from 670 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The quotient of the division is 86553.311, and the remainder is 0.0327.
