We're dividing 57460454 by 87 
The aim is to understand the frequency of 87 in 57460454.

Going ahead to step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 87

On to step 2:
The number 87 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 87

On to step 3:
If we divide 574 by 87, we get 6 and a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 522 away from 574, we end up with 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 87

Let's proceed to step 4:
526 divided by 87 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 522 from 526, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 87

Step 5:
87 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 660.0
Subtract 0 from 40 to get 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 87

Step 6:
The number 87 fits into 404 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 6604.0
The remainder is 56 after subtracting 348 from 404.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 87

Advancing to step 7:
When dividing 565 by 87, we get 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 66046.0
Deduct 522 from 565 and we're left with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 87

Step 8:
The number 87 fits into 434 4 times, leaving a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 660464.0
Deduct 348 from 434 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
When dividing 860 by 87, we get 9 with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 660464.9
Deduct 783 from 860 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 10:
When dividing 770 by 87, we get 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 660464.98
If we take 696 away from 770, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
When dividing 740 by 87, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 660464.988
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 660464.988 with a remainder of 0.0044.
