53661448 ÷ 97 
The aim is to understand the frequency of 97 in 53661448.

Going ahead to step 1:
97 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 97

Moving on to step 2:
If we divide 53 by 97, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 97

On to step 3:
97 goes into 536 5 times with a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 485 away from 536, we end up with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 97

Moving on to step 4:
516 divided by 97 is 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 485 from 516, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 97

Let's proceed to step 5:
When dividing 311 by 97, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 553.0
Deduct 291 from 311 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 97

Advancing to step 6:
The number 97 fits into 204 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 5532.0
If we take 194 away from 204, we end up with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 97

Going ahead to step 7:
If we divide 104 by 97, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 55321.0
Subtract 97 from 104 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 97

Advancing to step 8:
If we divide 78 by 97, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 553210.0
Deduct 0 from 78 and we're left 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.

Moving on to step 9:
780 divided by 97 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 553210.8
If we subtract 776 from 780, we 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.

On to step 10:
The number 97 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 553210.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 97, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 553210.804
If we take 388 away from 400, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 97 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 553210.8041
Deduct 97 from 120 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
97 goes into 230 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 553210.80412
If we take 194 away from 230, 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 14:
360 divided by 97 is 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 553210.804123
Deduct 291 from 360 and we're left 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.

Step 15:
When dividing 690 by 97, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 553210.8041237
Subtract 679 from 690 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 16:
110 divided by 97 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 553210.80412371
Subtracting 97 from 110 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 553210.80412371 with a remaining 1.3e-08.
