19634757 ÷ 684 
The aim is to understand the frequency of 684 in 19634757.

Advancing to step 1:
1 divided by 684 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 684

Moving on to step 2:
When dividing 19 by 684, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 684

On to step 3:
684 goes into 196 0 times with a remainder of 196.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Include the next digit (3) from the dividend after 196, then repeat: 1963 / 684

Step 4:
684 can be fit into 1963 2 times, resulting in a remainder of 595.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1368 from 1963 to get 595.
Take the next digit (4) from the dividend and append it to 595, then repeat: 5954 / 684

Moving on to step 5:
If we divide 5954 by 684, we get 8 and a remainder of 482.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 5472 from 5954 and we're left with 482.
Include the next digit (7) from the dividend after 482, then repeat: 4827 / 684

Going ahead to step 6:
When dividing 4827 by 684, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 287.0
The remainder is 39 after subtracting 4788 from 4827.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 684

Step 7:
The number 684 fits into 395 0 times, leaving a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 2870.0
If we take 0 away from 395, we end up with 395.
Grab the next digit (7) from the dividend, add it to 395, then carry on: 3957 / 684

Moving on to step 8:
If we divide 3957 by 684, we get 5 and a remainder of 537.
The number 5 becomes the next digit in our result. 
Result so far: 28705.0
If we take 3420 away from 3957, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 9:
684 can be fit into 5370 7 times, resulting in a remainder of 582.
Write down 7 as next digit of the result. 
Result so far: 28705.7
Deduct 4788 from 5370 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 10:
When dividing 5820 by 684, we get 8 with a remainder of 348.
Record the quotient 8 as the next digit in the result. 
Result so far: 28705.78
If we take 5472 away from 5820, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 11:
If we divide 3480 by 684, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 28705.785
If we subtract 3420 from 3480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
684 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 28705.785
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 13:
The number 684 fits into 6000 8 times, leaving a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 28705.78508
Subtract 5472 from 6000 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 14:
If we divide 5280 by 684, we get 7 and a remainder of 492.
Put 7 as the next digit of the answer. 
Result so far: 28705.785087
Subtract 4788 from 5280 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 15:
684 can be fit into 4920 7 times, resulting in a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 28705.7850877
The remainder is 132 after subtracting 4788 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 28705.7850877, with a leftover of 1.32e-06.
