54452384 ÷ 887 
The aim is to understand the frequency of 887 in 54452384.

Step 1:
When dividing 5 by 887, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 887

Moving on to step 2:
887 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 887

Advancing to step 3:
887 goes into 544 0 times with a remainder of 544.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 544 and we're left with 544.
Grab the next digit (5) from the dividend, add it to 544, then carry on: 5445 / 887

Let's proceed to step 4:
887 goes into 5445 6 times with a remainder of 123.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 5322 from 5445, we get 123.
Append the next digit (2) from the dividend to 123 and continue with: 1232 / 887

On to step 5:
When dividing 1232 by 887, we get 1 with a remainder of 345.
The next digit of our result is 1. 
Result so far: 61.0
Subtract 887 from 1232 to get 345.
Bring next digit (3) of the dividend behind the 345 and repeat the process: 3453 / 887

Advancing to step 6:
When dividing 3453 by 887, we get 3 with a remainder of 792.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
Subtracting 2661 from 3453 leaves us with 792.
Include the next digit (8) from the dividend after 792, then repeat: 7928 / 887

Moving on to step 7:
The number 887 fits into 7928 8 times, leaving a remainder of 832.
Record the quotient 8 as the next digit in the result. 
Result so far: 6138.0
Subtracting 7096 from 7928 leaves us with 832.
Append the next digit (4) from the dividend to 832 and continue with: 8324 / 887

Let's proceed to step 8:
The number 887 fits into 8324 9 times, leaving a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 61389.0
Subtract 7983 from 8324 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
The number 887 fits into 3410 3 times, leaving a remainder of 749.
Record the quotient 3 as the next digit in the result. 
Result so far: 61389.3
Deduct 2661 from 3410 and we're left with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Advancing to step 10:
7490 divided by 887 is 8 with a remainder of 394.
The next digit of our result is 8. 
Result so far: 61389.38
Deduct 7096 from 7490 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 11:
If we divide 3940 by 887, we get 4 and a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 61389.384
Deduct 3548 from 3940 and we're left with 392.
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 12:
When dividing 3920 by 887, we get 4 with a remainder of 372.
Put 4 as the next digit of the answer. 
Result so far: 61389.3844
The remainder is 372 after subtracting 3548 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 61389.3844 and a remainder of 0.00372.
