We look at the division of 57406512 by 487 
The aim is to understand the frequency of 487 in 57406512.

Let's proceed to step 1:
When dividing 5 by 487, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 487

Let's proceed to step 2:
487 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 487

Let's proceed to step 3:
If we divide 574 by 487, we get 1 and a remainder of 87.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 87 after subtracting 487 from 574.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 487

On to step 4:
487 goes into 870 1 times with a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 487 away from 870, we end up with 383.
Append the next digit (6) from the dividend to 383 and continue with: 3836 / 487

Going ahead to step 5:
487 goes into 3836 7 times with a remainder of 427.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 3409 from 3836 leaves us with 427.
Fetch the next digit (5) from the dividend, attach it to 427 and continue: 4275 / 487

Moving on to step 6:
487 goes into 4275 8 times with a remainder of 379.
Write down 8 as next digit of the result. 
Result so far: 1178.0
If we take 3896 away from 4275, we end up with 379.
Append the next digit (1) from the dividend to 379 and continue with: 3791 / 487

Let's proceed to step 7:
The number 487 fits into 3791 7 times, leaving a remainder of 382.
Put 7 as the next digit of the answer. 
Result so far: 11787.0
Deduct 3409 from 3791 and we're left with 382.
Take the next digit (2) from the dividend and append it to 382, then repeat: 3822 / 487

Advancing to step 8:
487 goes into 3822 7 times with a remainder of 413.
Record the quotient 7 as the next digit in the result. 
Result so far: 117877.0
Subtract 3409 from 3822 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 9:
4130 divided by 487 is 8 with a remainder of 234.
Write down 8 as next digit of the result. 
Result so far: 117877.8
If we take 3896 away from 4130, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 10:
When dividing 2340 by 487, we get 4 with a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 117877.84
The remainder is 392 after subtracting 1948 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 11:
487 goes into 3920 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 117877.848
If we subtract 3896 from 3920, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 487 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 117877.848
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
If we divide 2400 by 487, we get 4 and a remainder of 452.
Write down 4 as next digit of the result. 
Result so far: 117877.84804
If we subtract 1948 from 2400, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 14:
When dividing 4520 by 487, we get 9 with a remainder of 137.
Write down 9 as next digit of the result. 
Result so far: 117877.848049
The remainder is 137 after subtracting 4383 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 15:
487 goes into 1370 2 times with a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 117877.8480492
Deduct 974 from 1370 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.

Going ahead to step 16:
3960 divided by 487 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 117877.84804928
Deduct 3896 from 3960 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 117877.84804928 with a remaining 6.4e-08.
