40381372 ÷ 97 
The aim is to understand the frequency of 97 in 40381372.

Let's proceed to step 1:
If we divide 4 by 97, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 97

Step 2:
97 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 97

Advancing to step 3:
The number 97 fits into 403 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 15 after subtracting 388 from 403.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 97

On to step 4:
158 divided by 97 is 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 97 from 158 leaves us with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 97

On to step 5:
If we divide 611 by 97, we get 6 and a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Subtract 582 from 611 to get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 97

On to step 6:
The number 97 fits into 293 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 4163.0
Subtracting 291 from 293 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 97

Step 7:
When dividing 27 by 97, we get 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 41630.0
If we take 0 away from 27, we end up with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 97

Step 8:
If we divide 272 by 97, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 416302.0
Subtracting 194 from 272 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
When dividing 780 by 97, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 416302.8
Subtract 776 from 780 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 97, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 416302.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 97, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 416302.804
If we subtract 388 from 400, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
The number 97 fits into 120 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 416302.8041
The remainder is 23 after subtracting 97 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
97 goes into 230 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 416302.80412
The remainder is 36 after subtracting 194 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
97 goes into 360 3 times with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 416302.804123
If we take 291 away from 360, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 15:
690 divided by 97 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 416302.8041237
Deduct 679 from 690 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 16:
97 goes into 110 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 416302.80412371
The remainder is 13 after subtracting 97 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 416302.80412371 and a remainder of 1.3e-08.
