We're dividing 83838287 by 684 
The aim is to understand the frequency of 684 in 83838287.

Moving on to step 1:
The number 684 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 684

Moving on to step 2:
684 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 684

Going ahead to step 3:
If we divide 838 by 684, we get 1 and a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 154 after subtracting 684 from 838.
Grab the next digit (3) from the dividend, add it to 154, then carry on: 1543 / 684

Advancing to step 4:
1543 divided by 684 is 2 with a remainder of 175.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1368 from 1543 and we're left with 175.
Include the next digit (8) from the dividend after 175, then repeat: 1758 / 684

Let's proceed to step 5:
When dividing 1758 by 684, we get 2 with a remainder of 390.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 1368 from 1758 and we're left with 390.
Grab the next digit (2) from the dividend, add it to 390, then carry on: 3902 / 684

Moving on to step 6:
684 goes into 3902 5 times with a remainder of 482.
The next digit of our result is 5. 
Result so far: 1225.0
Subtract 3420 from 3902 to get 482.
Fetch the next digit (8) from the dividend, attach it to 482 and continue: 4828 / 684

Advancing to step 7:
If we divide 4828 by 684, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 12257.0
Subtract 4788 from 4828 to get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 684

Moving on to step 8:
684 goes into 407 0 times with a remainder of 407.
Record the quotient 0 as the next digit in the result. 
Result so far: 122570.0
If we take 0 away from 407, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 9:
The number 684 fits into 4070 5 times, leaving a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 122570.5
Deduct 3420 from 4070 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
684 can be fit into 6500 9 times, resulting in a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 122570.59
The remainder is 344 after subtracting 6156 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 11:
If we divide 3440 by 684, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 122570.595
If we take 3420 away from 3440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 684, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 122570.595
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
684 can be fit into 2000 2 times, resulting in a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 122570.59502
If we subtract 1368 from 2000, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 14:
684 can be fit into 6320 9 times, resulting in a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 122570.595029
Subtracting 6156 from 6320 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
If we divide 1640 by 684, we get 2 and a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 122570.5950292
The remainder is 272 after subtracting 1368 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 16:
The number 684 fits into 2720 3 times, leaving a remainder of 668.
The number 3 becomes the next digit in our result. 
Result so far: 122570.59502923
Subtract 2052 from 2720 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

After the division, we end up with 122570.59502923 and a remainder of 6.68e-07.
