17138648 ÷ 74 
The aim is to understand the frequency of 74 in 17138648.

Going ahead to step 1:
When dividing 1 by 74, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 74

Step 2:
The number 74 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 74

On to step 3:
74 can be fit into 171 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 148 from 171 and we're left with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 74

Moving on to step 4:
When dividing 233 by 74, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 222 away from 233, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 74

Moving on to step 5:
The number 74 fits into 118 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 231.0
Subtracting 74 from 118 leaves us with 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 74

Let's proceed to step 6:
If we divide 446 by 74, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 2316.0
If we subtract 444 from 446, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 74

Moving on to step 7:
When dividing 24 by 74, we get 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 23160.0
Subtracting 0 from 24 leaves us with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 74

Let's proceed to step 8:
74 goes into 248 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 231603.0
Subtracting 222 from 248 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
74 can be fit into 260 3 times, resulting in a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 231603.3
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
74 can be fit into 380 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 231603.35
The remainder is 10 after subtracting 370 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
74 goes into 100 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 231603.351
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 231603.3513
If we take 222 away from 260, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
When dividing 380 by 74, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 231603.35135
The remainder is 10 after subtracting 370 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 74, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 231603.351351
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 15:
260 divided by 74 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 231603.3513513
If we take 222 away from 260, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 16:
The number 74 fits into 380 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 231603.35135135
If we take 370 away from 380, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 231603.35135135, with a leftover of 1e-08.
