87453584 divided by 852 
The aim is to understand the frequency of 852 in 87453584.

On to step 1:
852 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 852

Going ahead to step 2:
852 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 852

Let's proceed to step 3:
When dividing 874 by 852, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 852 from 874 to get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 852

Advancing to step 4:
852 can be fit into 225 0 times, resulting in a remainder of 225.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 225 and we're left with 225.
Grab the next digit (3) from the dividend, add it to 225, then carry on: 2253 / 852

Moving on to step 5:
If we divide 2253 by 852, we get 2 and a remainder of 549.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 1704 from 2253 leaves us with 549.
Include the next digit (5) from the dividend after 549, then repeat: 5495 / 852

Moving on to step 6:
The number 852 fits into 5495 6 times, leaving a remainder of 383.
The next digit of our result is 6. 
Result so far: 1026.0
Deduct 5112 from 5495 and we're left with 383.
Include the next digit (8) from the dividend after 383, then repeat: 3838 / 852

On to step 7:
852 goes into 3838 4 times with a remainder of 430.
The next digit of our result is 4. 
Result so far: 10264.0
If we take 3408 away from 3838, we end up with 430.
Grab the next digit (4) from the dividend, add it to 430, then carry on: 4304 / 852

Let's proceed to step 8:
852 goes into 4304 5 times with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 102645.0
If we subtract 4260 from 4304, 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.

Going ahead to step 9:
440 divided by 852 is 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 102645.0
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
4400 divided by 852 is 5 with a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 102645.05
Subtracting 4260 from 4400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 852 fits into 1400 1 times, leaving a remainder of 548.
Write down 1 as next digit of the result. 
Result so far: 102645.051
The remainder is 548 after subtracting 852 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 12:
852 goes into 5480 6 times with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 102645.0516
Deduct 5112 from 5480 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
852 can be fit into 3680 4 times, resulting in a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 102645.05164
If we subtract 3408 from 3680, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
2720 divided by 852 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 102645.051643
Deduct 2556 from 2720 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 15:
When dividing 1640 by 852, we get 1 with a remainder of 788.
Use 1 as the next digit of our solution. 
Result so far: 102645.0516431
Deduct 852 from 1640 and we're left with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Let's proceed to step 16:
The number 852 fits into 7880 9 times, leaving a remainder of 212.
The next digit of our result is 9. 
Result so far: 102645.05164319
Subtract 7668 from 7880 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

After the division, we end up with 102645.05164319 and a remainder of 2.12e-07.
