Let's divide 18787542 by 173
The aim is to understand the frequency of 173 in 18787542.

Let's proceed to step 1:
When dividing 1 by 173, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 173

Let's proceed to step 2:
When dividing 18 by 173, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 173

On to step 3:
173 goes into 187 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 173 from 187 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 173

Moving on to step 4:
If we divide 148 by 173, we get 0 and a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 148 and we're left with 148.
Bring next digit (7) of the dividend behind the 148 and repeat the process: 1487 / 173

Moving on to step 5:
173 can be fit into 1487 8 times, resulting in a remainder of 103.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 1384 from 1487 leaves us with 103.
Grab the next digit (5) from the dividend, add it to 103, then carry on: 1035 / 173

On to step 6:
When dividing 1035 by 173, we get 5 with a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
If we take 865 away from 1035, we end up with 170.
Take the next digit (4) from the dividend and append it to 170, then repeat: 1704 / 173

Going ahead to step 7:
173 can be fit into 1704 9 times, resulting in a remainder of 147.
Write down 9 as next digit of the result. 
Result so far: 10859.0
If we take 1557 away from 1704, we end up with 147.
Bring next digit (2) of the dividend behind the 147 and repeat the process: 1472 / 173

Step 8:
When dividing 1472 by 173, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 108598.0
Deduct 1384 from 1472 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
When dividing 880 by 173, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 108598.5
If we take 865 away from 880, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 173 fits into 150 0 times, leaving a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 108598.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
If we divide 1500 by 173, we get 8 and a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 108598.508
Subtracting 1384 from 1500 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
173 can be fit into 1160 6 times, resulting in a remainder of 122.
The next digit of our result is 6. 
Result so far: 108598.5086
Subtracting 1038 from 1160 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 13:
If we divide 1220 by 173, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 108598.50867
If we take 1211 away from 1220, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
When dividing 90 by 173, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 108598.50867
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
900 divided by 173 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 108598.5086705
Subtract 865 from 900 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 16:
350 divided by 173 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 108598.50867052
If we take 346 away from 350, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 108598.50867052 and a remainder of 4e-09.
