97988402 ÷ 38 
The aim is to understand the frequency of 38 in 97988402.

Moving on to step 1:
The number 38 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 38

On to step 2:
97 divided by 38 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 21 after subtracting 76 from 97.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 38

Moving on to step 3:
The number 38 fits into 219 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 190 from 219, we get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 38

Going ahead to step 4:
The number 38 fits into 298 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 257.0
Subtract 266 from 298 to get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 38

Advancing to step 5:
38 goes into 328 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2578.0
The remainder is 24 after subtracting 304 from 328.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 38

Advancing to step 6:
If we divide 244 by 38, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 25786.0
Deduct 228 from 244 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 38

Going ahead to step 7:
The number 38 fits into 160 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 257864.0
Subtract 152 from 160 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 38

Step 8:
If we divide 82 by 38, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2578642.0
Subtract 76 from 82 to 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.

Moving on to step 9:
When dividing 60 by 38, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2578642.1
If we take 38 away from 60, we end up with 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 10:
If we divide 220 by 38, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 2578642.15
If we take 190 away from 220, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 38 fits into 300 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 2578642.157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 38 fits into 340 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 2578642.1578
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
38 can be fit into 360 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 2578642.15789
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
The number 38 fits into 180 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2578642.157894
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 15:
38 can be fit into 280 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 2578642.1578947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 16:
When dividing 140 by 38, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 2578642.15789473
If we take 114 away from 140, we end up 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.

The quotient of the division is 2578642.15789473, and the remainder is 2.6e-08.
