We're dividing 64902840 by 102 
The aim is to understand the frequency of 102 in 64902840.

On to step 1:
6 divided by 102 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 102

On to step 2:
102 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 102

Let's proceed to step 3:
When dividing 649 by 102, we get 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 37 after subtracting 612 from 649.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 102

Step 4:
If we divide 370 by 102, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 306 from 370 leaves us with 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 102

Going ahead to step 5:
642 divided by 102 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 636.0
If we take 612 away from 642, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 102

Step 6:
308 divided by 102 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 6363.0
The remainder is 2 after subtracting 306 from 308.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 102

Moving on to step 7:
24 divided by 102 is 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 63630.0
Subtract 0 from 24 to get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 102

Moving on to step 8:
102 goes into 240 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 636302.0
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 102, we get 3 and a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 636302.3
Subtracting 306 from 360 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
102 goes into 540 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 636302.35
Deduct 510 from 540 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
102 can be fit into 300 2 times, resulting in a remainder of 96.
The next digit of our result is 2. 
Result so far: 636302.352
Subtract 204 from 300 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
When dividing 960 by 102, we get 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 636302.3529
If we subtract 918 from 960, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
420 divided by 102 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 636302.35294
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
102 goes into 120 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 636302.352941
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
102 can be fit into 180 1 times, resulting in a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 636302.3529411
If we take 102 away from 180, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 636302.3529411 with a remaining 7.8e-07.
