We divide 400646 by 97
The aim is to understand the frequency of 97 in 400646.

Going ahead to step 1:
When dividing 4 by 97, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 97

Let's proceed to step 2:
The number 97 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 97

Let's proceed to step 3:
If we divide 400 by 97, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 388 from 400 to get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 97

Let's proceed to step 4:
97 goes into 126 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we subtract 97 from 126, we get 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 97

Step 5:
When dividing 294 by 97, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 413.0
Subtract 291 from 294 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 97

Moving on to step 6:
97 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 4130.0
If we take 0 away from 36, 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.

Going ahead to step 7:
The number 97 fits into 360 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 4130.3
If we subtract 291 from 360, we get 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 8:
When dividing 690 by 97, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4130.37
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.

On to step 9:
97 goes into 110 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 4130.371
If we subtract 97 from 110, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
130 divided by 97 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 4130.3711
If we take 97 away from 130, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 4130.3711 with a remaining 0.00033.
