We're dividing 45229028 by 397 
The aim is to understand the frequency of 397 in 45229028.

Advancing to step 1:
4 divided by 397 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 397

Moving on to step 2:
397 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 397

On to step 3:
When dividing 452 by 397, we get 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 397 from 452 and we're left with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 397

Step 4:
The number 397 fits into 552 1 times, leaving a remainder of 155.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 397 from 552 leaves us with 155.
Fetch the next digit (9) from the dividend, attach it to 155 and continue: 1559 / 397

Moving on to step 5:
397 goes into 1559 3 times with a remainder of 368.
The next digit of our result is 3. 
Result so far: 113.0
The remainder is 368 after subtracting 1191 from 1559.
Include the next digit (0) from the dividend after 368, then repeat: 3680 / 397

Moving on to step 6:
When dividing 3680 by 397, we get 9 with a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 1139.0
Deduct 3573 from 3680 and we're left with 107.
Grab the next digit (2) from the dividend, add it to 107, then carry on: 1072 / 397

On to step 7:
397 goes into 1072 2 times with a remainder of 278.
The next digit of our result is 2. 
Result so far: 11392.0
The remainder is 278 after subtracting 794 from 1072.
Fetch the next digit (8) from the dividend, attach it to 278 and continue: 2788 / 397

Going ahead to step 8:
397 goes into 2788 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 113927.0
Subtracting 2779 from 2788 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
397 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 113927.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
397 goes into 900 2 times with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 113927.02
If we take 794 away from 900, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
397 can be fit into 1060 2 times, resulting in a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 113927.022
If we take 794 away from 1060, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 113927.022, and the remainder is 0.0266.
