We look at the division of 75397738 by 882 
The aim is to understand the frequency of 882 in 75397738.

On to step 1:
The number 882 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 882

Let's proceed to step 2:
If we divide 75 by 882, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 882

On to step 3:
When dividing 753 by 882, we get 0 with a remainder of 753.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 753 after subtracting 0 from 753.
Append the next digit (9) from the dividend to 753 and continue with: 7539 / 882

Let's proceed to step 4:
When dividing 7539 by 882, we get 8 with a remainder of 483.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7056 from 7539 leaves us with 483.
Take the next digit (7) from the dividend and append it to 483, then repeat: 4837 / 882

Step 5:
882 can be fit into 4837 5 times, resulting in a remainder of 427.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 4410 from 4837 leaves us with 427.
Bring next digit (7) of the dividend behind the 427 and repeat the process: 4277 / 882

Step 6:
The number 882 fits into 4277 4 times, leaving a remainder of 749.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Subtracting 3528 from 4277 leaves us with 749.
Fetch the next digit (3) from the dividend, attach it to 749 and continue: 7493 / 882

On to step 7:
The number 882 fits into 7493 8 times, leaving a remainder of 437.
Use 8 as the next digit of our solution. 
Result so far: 8548.0
Subtracting 7056 from 7493 leaves us with 437.
Bring next digit (8) of the dividend behind the 437 and repeat the process: 4378 / 882

Moving on to step 8:
882 can be fit into 4378 4 times, resulting in a remainder of 850.
Write down 4 as next digit of the result. 
Result so far: 85484.0
If we take 3528 away from 4378, we end up with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Going ahead to step 9:
If we divide 8500 by 882, we get 9 and a remainder of 562.
Put 9 as the next digit of the answer. 
Result so far: 85484.9
Subtract 7938 from 8500 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 10:
882 goes into 5620 6 times with a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 85484.96
Subtracting 5292 from 5620 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 11:
882 can be fit into 3280 3 times, resulting in a remainder of 634.
The next digit of our result is 3. 
Result so far: 85484.963
Subtract 2646 from 3280 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

On to step 12:
The number 882 fits into 6340 7 times, leaving a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 85484.9637
Subtract 6174 from 6340 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 13:
When dividing 1660 by 882, we get 1 with a remainder of 778.
Use 1 as the next digit of our solution. 
Result so far: 85484.96371
If we take 882 away from 1660, we end up with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Advancing to step 14:
The number 882 fits into 7780 8 times, leaving a remainder of 724.
Write down 8 as next digit of the result. 
Result so far: 85484.963718
Deduct 7056 from 7780 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 15:
When dividing 7240 by 882, we get 8 with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 85484.9637188
Subtracting 7056 from 7240 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

After the division, we end up with 85484.9637188 and a remainder of 1.84e-06.
