We look at the division of 5783070 by 684 
The aim is to understand the frequency of 684 in 5783070.

On to step 1:
When dividing 5 by 684, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 684

Advancing to step 2:
When dividing 57 by 684, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 684

Going ahead to step 3:
578 divided by 684 is 0 with a remainder of 578.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 578 after subtracting 0 from 578.
Take the next digit (3) from the dividend and append it to 578, then repeat: 5783 / 684

Moving on to step 4:
684 can be fit into 5783 8 times, resulting in a remainder of 311.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5472 away from 5783, we end up with 311.
Grab the next digit (0) from the dividend, add it to 311, then carry on: 3110 / 684

On to step 5:
684 can be fit into 3110 4 times, resulting in a remainder of 374.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 374 after subtracting 2736 from 3110.
Append the next digit (7) from the dividend to 374 and continue with: 3747 / 684

Let's proceed to step 6:
If we divide 3747 by 684, we get 5 and a remainder of 327.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
If we subtract 3420 from 3747, we get 327.
Append the next digit (0) from the dividend to 327 and continue with: 3270 / 684

Moving on to step 7:
When dividing 3270 by 684, we get 4 with a remainder of 534.
The next digit of our result is 4. 
Result so far: 8454.0
If we subtract 2736 from 3270, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 8:
If we divide 5340 by 684, we get 7 and a remainder of 552.
Put 7 as the next digit of the answer. 
Result so far: 8454.7
The remainder is 552 after subtracting 4788 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 9:
If we divide 5520 by 684, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8454.78
Subtracting 5472 from 5520 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
684 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 8454.78
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
684 goes into 4800 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 8454.7807
Subtract 4788 from 4800 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 12:
When dividing 120 by 684, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 8454.7807
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
The number 684 fits into 1200 1 times, leaving a remainder of 516.
Use 1 as the next digit of our solution. 
Result so far: 8454.780701
Subtract 684 from 1200 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 14:
The number 684 fits into 5160 7 times, leaving a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 8454.7807017
If we subtract 4788 from 5160, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 15:
684 goes into 3720 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 8454.78070175
Deduct 3420 from 3720 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 8454.78070175 with a remaining 3e-07.
