We're dividing 28908697 by 840 
The aim is to understand the frequency of 840 in 28908697.

Advancing to step 1:
The number 840 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 840

Advancing to step 2:
840 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 840

Let's proceed to step 3:
840 goes into 289 0 times with a remainder of 289.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 289 leaves us with 289.
Fetch the next digit (0) from the dividend, attach it to 289 and continue: 2890 / 840

Step 4:
If we divide 2890 by 840, we get 3 and a remainder of 370.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 370 after subtracting 2520 from 2890.
Grab the next digit (8) from the dividend, add it to 370, then carry on: 3708 / 840

Let's proceed to step 5:
3708 divided by 840 is 4 with a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 3360 from 3708 to get 348.
Bring next digit (6) of the dividend behind the 348 and repeat the process: 3486 / 840

Let's proceed to step 6:
When dividing 3486 by 840, we get 4 with a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 344.0
If we subtract 3360 from 3486, we get 126.
Include the next digit (9) from the dividend after 126, then repeat: 1269 / 840

On to step 7:
840 goes into 1269 1 times with a remainder of 429.
Use 1 as the next digit of our solution. 
Result so far: 3441.0
If we subtract 840 from 1269, we get 429.
Fetch the next digit (7) from the dividend, attach it to 429 and continue: 4297 / 840

Going ahead to step 8:
When dividing 4297 by 840, we get 5 with a remainder of 97.
The number 5 becomes the next digit in our result. 
Result so far: 34415.0
Deduct 4200 from 4297 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
When dividing 970 by 840, we get 1 with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 34415.1
Deduct 840 from 970 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
If we divide 1300 by 840, we get 1 and a remainder of 460.
Use 1 as the next digit of our solution. 
Result so far: 34415.11
If we take 840 away from 1300, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Our division results in 34415.11 with a remaining 0.46.
