We divide 52489478 by 668
The aim is to understand the frequency of 668 in 52489478.

Going ahead to step 1:
5 divided by 668 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 668

On to step 2:
When dividing 52 by 668, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 668

Let's proceed to step 3:
When dividing 524 by 668, we get 0 with a remainder of 524.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 524 and we're left with 524.
Include the next digit (8) from the dividend after 524, then repeat: 5248 / 668

Advancing to step 4:
The number 668 fits into 5248 7 times, leaving a remainder of 572.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4676 from 5248 to get 572.
Grab the next digit (9) from the dividend, add it to 572, then carry on: 5729 / 668

Moving on to step 5:
When dividing 5729 by 668, we get 8 with a remainder of 385.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 385 after subtracting 5344 from 5729.
Append the next digit (4) from the dividend to 385 and continue with: 3854 / 668

Let's proceed to step 6:
668 can be fit into 3854 5 times, resulting in a remainder of 514.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
Subtract 3340 from 3854 to get 514.
Include the next digit (7) from the dividend after 514, then repeat: 5147 / 668

Moving on to step 7:
The number 668 fits into 5147 7 times, leaving a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 7857.0
If we take 4676 away from 5147, we end up with 471.
Bring next digit (8) of the dividend behind the 471 and repeat the process: 4718 / 668

Step 8:
When dividing 4718 by 668, we get 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 78577.0
If we subtract 4676 from 4718, 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.

On to step 9:
420 divided by 668 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 78577.0
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
4200 divided by 668 is 6 with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 78577.06
If we take 4008 away from 4200, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 11:
When dividing 1920 by 668, we get 2 with a remainder of 584.
Record the quotient 2 as the next digit in the result. 
Result so far: 78577.062
If we take 1336 away from 1920, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 12:
5840 divided by 668 is 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 78577.0628
Deduct 5344 from 5840 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 13:
The number 668 fits into 4960 7 times, leaving a remainder of 284.
Put 7 as the next digit of the answer. 
Result so far: 78577.06287
Subtract 4676 from 4960 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 14:
The number 668 fits into 2840 4 times, leaving a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 78577.062874
Subtracting 2672 from 2840 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 15:
668 can be fit into 1680 2 times, resulting in a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 78577.0628742
Subtract 1336 from 1680 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 16:
668 goes into 3440 5 times with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 78577.06287425
Subtract 3340 from 3440 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 78577.06287425 with a remainder of 1e-07.
