35583098 ÷ 864 
The aim is to understand the frequency of 864 in 35583098.

Let's proceed to step 1:
If we divide 3 by 864, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 864

Going ahead to step 2:
35 divided by 864 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 864

Moving on to step 3:
864 can be fit into 355 0 times, resulting in a remainder of 355.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 355 leaves us with 355.
Fetch the next digit (8) from the dividend, attach it to 355 and continue: 3558 / 864

Going ahead to step 4:
864 goes into 3558 4 times with a remainder of 102.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 102 after subtracting 3456 from 3558.
Append the next digit (3) from the dividend to 102 and continue with: 1023 / 864

On to step 5:
1023 divided by 864 is 1 with a remainder of 159.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 864 from 1023, we get 159.
Grab the next digit (0) from the dividend, add it to 159, then carry on: 1590 / 864

Advancing to step 6:
864 can be fit into 1590 1 times, resulting in a remainder of 726.
Use 1 as the next digit of our solution. 
Result so far: 411.0
Subtract 864 from 1590 to get 726.
Grab the next digit (9) from the dividend, add it to 726, then carry on: 7269 / 864

On to step 7:
864 goes into 7269 8 times with a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 4118.0
If we take 6912 away from 7269, we end up with 357.
Take the next digit (8) from the dividend and append it to 357, then repeat: 3578 / 864

Going ahead to step 8:
When dividing 3578 by 864, we get 4 with a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 41184.0
Subtracting 3456 from 3578 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
The number 864 fits into 1220 1 times, leaving a remainder of 356.
Write down 1 as next digit of the result. 
Result so far: 41184.1
Subtracting 864 from 1220 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 10:
The number 864 fits into 3560 4 times, leaving a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 41184.14
If we take 3456 away from 3560, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
864 can be fit into 1040 1 times, resulting in a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 41184.141
If we take 864 away from 1040, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
1760 divided by 864 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 41184.1412
Deduct 1728 from 1760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 864, we get 0 and a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 41184.1412
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
864 can be fit into 3200 3 times, resulting in a remainder of 608.
Put 3 as the next digit of the answer. 
Result so far: 41184.141203
Deduct 2592 from 3200 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 15:
The number 864 fits into 6080 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 41184.1412037
If we take 6048 away from 6080, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 864, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 41184.1412037
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 41184.1412037 and a remainder of 3.2e-07.
