18109867 divided by 154 
The aim is to understand the frequency of 154 in 18109867.

Going ahead to step 1:
When dividing 1 by 154, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 154

On to step 2:
If we divide 18 by 154, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 154

Let's proceed to step 3:
When dividing 181 by 154, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 154 from 181 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 154

Moving on to step 4:
When dividing 270 by 154, we get 1 with a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 154 from 270 leaves us with 116.
Grab the next digit (9) from the dividend, add it to 116, then carry on: 1169 / 154

Going ahead to step 5:
1169 divided by 154 is 7 with a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 1078 from 1169 leaves us with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 154

Step 6:
The number 154 fits into 918 5 times, leaving a remainder of 148.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
Deduct 770 from 918 and we're left with 148.
Fetch the next digit (6) from the dividend, attach it to 148 and continue: 1486 / 154

Moving on to step 7:
1486 divided by 154 is 9 with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 11759.0
Deduct 1386 from 1486 and we're left with 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 154

Step 8:
When dividing 1007 by 154, we get 6 with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 117596.0
If we subtract 924 from 1007, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
The number 154 fits into 830 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 117596.5
If we take 770 away from 830, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
600 divided by 154 is 3 with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 117596.53
The remainder is 138 after subtracting 462 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
1380 divided by 154 is 8 with a remainder of 148.
The next digit of our result is 8. 
Result so far: 117596.538
Subtracting 1232 from 1380 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 12:
The number 154 fits into 1480 9 times, leaving a remainder of 94.
Use 9 as the next digit of our solution. 
Result so far: 117596.5389
Subtracting 1386 from 1480 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 13:
If we divide 940 by 154, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 117596.53896
Deduct 924 from 940 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
154 can be fit into 160 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 117596.538961
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
154 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 117596.538961
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
If we divide 600 by 154, we get 3 and a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 117596.53896103
Subtract 462 from 600 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

In conclusion, the division gives 117596.53896103 with a balance of 1.38e-07.
