We look at the division of 18871386 by 293 
The aim is to understand the frequency of 293 in 18871386.

Advancing to step 1:
1 divided by 293 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 293

Moving on to step 2:
The number 293 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 293

Moving on to step 3:
188 divided by 293 is 0 with a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Bring next digit (7) of the dividend behind the 188 and repeat the process: 1887 / 293

Advancing to step 4:
293 can be fit into 1887 6 times, resulting in a remainder of 129.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1758 away from 1887, we end up with 129.
Fetch the next digit (1) from the dividend, attach it to 129 and continue: 1291 / 293

On to step 5:
293 goes into 1291 4 times with a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 1172 from 1291, we get 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 293

On to step 6:
If we divide 1193 by 293, we get 4 and a remainder of 21.
The next digit of our result is 4. 
Result so far: 644.0
Subtracting 1172 from 1193 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 293

Going ahead to step 7:
293 goes into 218 0 times with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 6440.0
If we take 0 away from 218, we end up with 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 293

Let's proceed to step 8:
2186 divided by 293 is 7 with a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 64407.0
Subtract 2051 from 2186 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
The number 293 fits into 1350 4 times, leaving a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 64407.4
Subtracting 1172 from 1350 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
1780 divided by 293 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 64407.46
Subtract 1758 from 1780 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 293, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 64407.46
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
2200 divided by 293 is 7 with a remainder of 149.
The next digit of our result is 7. 
Result so far: 64407.4607
If we subtract 2051 from 2200, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 13:
1490 divided by 293 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 64407.46075
Subtract 1465 from 1490 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
The number 293 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 64407.46075
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
293 goes into 2500 8 times with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 64407.4607508
Subtract 2344 from 2500 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 16:
1560 divided by 293 is 5 with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 64407.46075085
If we subtract 1465 from 1560, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

In conclusion, the division gives 64407.46075085 with a balance of 9.5e-08.
