We look at the division of 39840497 by 352 
The aim is to understand the frequency of 352 in 39840497.

Moving on to step 1:
When dividing 3 by 352, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 352

On to step 2:
The number 352 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 352

On to step 3:
398 divided by 352 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 352 from 398 to get 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 352

On to step 4:
464 divided by 352 is 1 with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 352 from 464 to get 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 352

Moving on to step 5:
1120 divided by 352 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 1056 from 1120, we get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 352

Moving on to step 6:
352 can be fit into 644 1 times, resulting in a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 1131.0
If we subtract 352 from 644, we get 292.
Bring next digit (9) of the dividend behind the 292 and repeat the process: 2929 / 352

Advancing to step 7:
If we divide 2929 by 352, we get 8 and a remainder of 113.
The next digit of our result is 8. 
Result so far: 11318.0
Deduct 2816 from 2929 and we're left with 113.
Bring next digit (7) of the dividend behind the 113 and repeat the process: 1137 / 352

Moving on to step 8:
1137 divided by 352 is 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 113183.0
If we take 1056 away from 1137, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
352 can be fit into 810 2 times, resulting in a remainder of 106.
The number 2 becomes the next digit in our result. 
Result so far: 113183.2
Subtracting 704 from 810 leaves us 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.

Moving on to step 10:
The number 352 fits into 1060 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 113183.23
Subtracting 1056 from 1060 leaves us with 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 11:
352 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 113183.23
Subtract 0 from 40 to get 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 12:
352 can be fit into 400 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 113183.2301
Subtract 352 from 400 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
The number 352 fits into 480 1 times, leaving a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 113183.23011
The remainder is 128 after subtracting 352 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 113183.23011, and the remainder is 0.000128.
