Let's divide 87256884 by 349
The aim is to understand the frequency of 349 in 87256884.

Moving on to step 1:
8 divided by 349 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 349

Let's proceed to step 2:
87 divided by 349 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 349

Moving on to step 3:
The number 349 fits into 872 2 times, leaving a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 174 after subtracting 698 from 872.
Fetch the next digit (5) from the dividend, attach it to 174 and continue: 1745 / 349

Moving on to step 4:
When dividing 1745 by 349, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 1745 from 1745 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 349

On to step 5:
349 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 349

Advancing to step 6:
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: 2500.0
If we take 0 away from 68, we end up with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 349

Advancing to step 7:
688 divided by 349 is 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 25001.0
Subtracting 349 from 688 leaves us with 339.
Append the next digit (4) from the dividend to 339 and continue with: 3394 / 349

On to step 8:
349 can be fit into 3394 9 times, resulting in a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 250019.0
The remainder is 253 after subtracting 3141 from 3394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 9:
2530 divided by 349 is 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 250019.7
The remainder is 87 after subtracting 2443 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
349 goes into 870 2 times with a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 250019.72
If we take 698 away from 870, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
The number 349 fits into 1720 4 times, leaving a remainder of 324.
Put 4 as the next digit of the answer. 
Result so far: 250019.724
Deduct 1396 from 1720 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 12:
349 goes into 3240 9 times with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 250019.7249
The remainder is 99 after subtracting 3141 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 13:
The number 349 fits into 990 2 times, leaving a remainder of 292.
The next digit of our result is 2. 
Result so far: 250019.72492
If we take 698 away from 990, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 14:
349 goes into 2920 8 times with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 250019.724928
Deduct 2792 from 2920 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
1280 divided by 349 is 3 with a remainder of 233.
The number 3 becomes the next digit in our result. 
Result so far: 250019.7249283
Deduct 1047 from 1280 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 16:
The number 349 fits into 2330 6 times, leaving a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 250019.72492836
The remainder is 236 after subtracting 2094 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

After the division, we end up with 250019.72492836 and a remainder of 2.36e-07.
