Let's divide 45389970 by 684
The aim is to understand the frequency of 684 in 45389970.

Let's proceed to step 1:
684 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 684

Going ahead to step 2:
45 divided by 684 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 684

Moving on to step 3:
453 divided by 684 is 0 with a remainder of 453.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 453 leaves us with 453.
Grab the next digit (8) from the dividend, add it to 453, then carry on: 4538 / 684

Step 4:
The number 684 fits into 4538 6 times, leaving a remainder of 434.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 4104 from 4538 to get 434.
Bring next digit (9) of the dividend behind the 434 and repeat the process: 4349 / 684

Going ahead to step 5:
684 goes into 4349 6 times with a remainder of 245.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 4104 from 4349, we get 245.
Include the next digit (9) from the dividend after 245, then repeat: 2459 / 684

Advancing to step 6:
The number 684 fits into 2459 3 times, leaving a remainder of 407.
The next digit of our result is 3. 
Result so far: 663.0
Deduct 2052 from 2459 and we're left with 407.
Grab the next digit (7) from the dividend, add it to 407, then carry on: 4077 / 684

Step 7:
4077 divided by 684 is 5 with a remainder of 657.
Use 5 as the next digit of our solution. 
Result so far: 6635.0
The remainder is 657 after subtracting 3420 from 4077.
Include the next digit (0) from the dividend after 657, then repeat: 6570 / 684

Moving on to step 8:
684 can be fit into 6570 9 times, resulting in a remainder of 414.
Use 9 as the next digit of our solution. 
Result so far: 66359.0
Deduct 6156 from 6570 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 9:
The number 684 fits into 4140 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 66359.6
Deduct 4104 from 4140 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
When dividing 360 by 684, we get 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 66359.6
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
684 goes into 3600 5 times with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 66359.605
If we take 3420 away from 3600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
If we divide 1800 by 684, we get 2 and a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 66359.6052
Deduct 1368 from 1800 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 13:
The number 684 fits into 4320 6 times, leaving a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 66359.60526
Subtracting 4104 from 4320 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
684 can be fit into 2160 3 times, resulting in a remainder of 108.
The next digit of our result is 3. 
Result so far: 66359.605263
Deduct 2052 from 2160 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
If we divide 1080 by 684, we get 1 and a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 66359.6052631
Deduct 684 from 1080 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 16:
If we divide 3960 by 684, we get 5 and a remainder of 540.
Use 5 as the next digit of our solution. 
Result so far: 66359.60526315
The remainder is 540 after subtracting 3420 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 66359.60526315, with a leftover of 5.4e-07.
