Let's divide 68421569 by 349
The aim is to understand the frequency of 349 in 68421569.

Step 1:
When dividing 6 by 349, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 349

On to step 2:
When dividing 68 by 349, we get 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 349

Going ahead to step 3:
349 goes into 684 1 times with a remainder of 335.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 349 from 684 to get 335.
Bring next digit (2) of the dividend behind the 335 and repeat the process: 3352 / 349

Let's proceed to step 4:
If we divide 3352 by 349, we get 9 and a remainder of 211.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 3141 from 3352 to get 211.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 349

Let's proceed to step 5:
When dividing 2111 by 349, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 196.0
Deduct 2094 from 2111 and we're left with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 349

Going ahead to step 6:
349 can be fit into 175 0 times, resulting in a remainder of 175.
The next digit of our result is 0. 
Result so far: 1960.0
If we take 0 away from 175, we end up with 175.
Grab the next digit (6) from the dividend, add it to 175, then carry on: 1756 / 349

Step 7:
The number 349 fits into 1756 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 19605.0
Subtracting 1745 from 1756 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 349

Going ahead to step 8:
119 divided by 349 is 0 with a remainder of 119.
The next digit of our result is 0. 
Result so far: 196050.0
If we take 0 away from 119, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 9:
349 can be fit into 1190 3 times, resulting in a remainder of 143.
Write down 3 as next digit of the result. 
Result so far: 196050.3
Subtract 1047 from 1190 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 10:
The number 349 fits into 1430 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 196050.34
If we take 1396 away from 1430, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
349 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 196050.34
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
349 goes into 3400 9 times with a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 196050.3409
If we take 3141 away from 3400, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 13:
The number 349 fits into 2590 7 times, leaving a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 196050.34097
If we take 2443 away from 2590, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 14:
1470 divided by 349 is 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 196050.340974
Subtracting 1396 from 1470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
349 can be fit into 740 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 196050.3409742
If we subtract 698 from 740, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
The number 349 fits into 420 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 196050.34097421
Subtract 349 from 420 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 196050.34097421 with a remaining 7.1e-08.
