Let's divide 86868913 by 348
The aim is to understand the frequency of 348 in 86868913.

Moving on to step 1:
348 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 348

Going ahead to step 2:
If we divide 86 by 348, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 348

Moving on to step 3:
The number 348 fits into 868 2 times, leaving a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 696 from 868 to get 172.
Take the next digit (6) from the dividend and append it to 172, then repeat: 1726 / 348

On to step 4:
When dividing 1726 by 348, we get 4 with a remainder of 334.
The next digit of our result is 4. 
Result so far: 24.0
If we take 1392 away from 1726, we end up with 334.
Fetch the next digit (8) from the dividend, attach it to 334 and continue: 3348 / 348

Advancing to step 5:
The number 348 fits into 3348 9 times, leaving a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 249.0
The remainder is 216 after subtracting 3132 from 3348.
Grab the next digit (9) from the dividend, add it to 216, then carry on: 2169 / 348

Moving on to step 6:
When dividing 2169 by 348, we get 6 with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 2496.0
Subtract 2088 from 2169 to get 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 348

Moving on to step 7:
If we divide 811 by 348, we get 2 and a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 24962.0
The remainder is 115 after subtracting 696 from 811.
Include the next digit (3) from the dividend after 115, then repeat: 1153 / 348

On to step 8:
The number 348 fits into 1153 3 times, leaving a remainder of 109.
The next digit of our result is 3. 
Result so far: 249623.0
The remainder is 109 after subtracting 1044 from 1153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
348 goes into 1090 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 249623.3
Subtracting 1044 from 1090 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
The number 348 fits into 460 1 times, leaving a remainder of 112.
The next digit of our result is 1. 
Result so far: 249623.31
Subtract 348 from 460 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
348 can be fit into 1120 3 times, resulting in a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 249623.313
Subtracting 1044 from 1120 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
If we divide 760 by 348, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 249623.3132
Subtract 696 from 760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
348 can be fit into 640 1 times, resulting in a remainder of 292.
Write down 1 as next digit of the result. 
Result so far: 249623.31321
Subtracting 348 from 640 leaves us 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.

Moving on to step 14:
2920 divided by 348 is 8 with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 249623.313218
If we take 2784 away from 2920, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
348 can be fit into 1360 3 times, resulting in a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 249623.3132183
Subtract 1044 from 1360 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 16:
348 can be fit into 3160 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 249623.31321839
The remainder is 28 after subtracting 3132 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 249623.31321839 with a remainder of 2.8e-08.
