78104316 ÷ 852 
The aim is to understand the frequency of 852 in 78104316.

Step 1:
852 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 852

On to step 2:
852 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 852

Advancing to step 3:
If we divide 781 by 852, we get 0 and a remainder of 781.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 781 after subtracting 0 from 781.
Fetch the next digit (0) from the dividend, attach it to 781 and continue: 7810 / 852

Step 4:
If we divide 7810 by 852, we get 9 and a remainder of 142.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7668 from 7810 to get 142.
Take the next digit (4) from the dividend and append it to 142, then repeat: 1424 / 852

Advancing to step 5:
1424 divided by 852 is 1 with a remainder of 572.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 852 from 1424 to get 572.
Include the next digit (3) from the dividend after 572, then repeat: 5723 / 852

Moving on to step 6:
5723 divided by 852 is 6 with a remainder of 611.
Record the quotient 6 as the next digit in the result. 
Result so far: 916.0
If we subtract 5112 from 5723, we get 611.
Bring next digit (1) of the dividend behind the 611 and repeat the process: 6111 / 852

Moving on to step 7:
If we divide 6111 by 852, we get 7 and a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 9167.0
If we take 5964 away from 6111, we end up with 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 852

Moving on to step 8:
1476 divided by 852 is 1 with a remainder of 624.
Record the quotient 1 as the next digit in the result. 
Result so far: 91671.0
Subtracting 852 from 1476 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 9:
6240 divided by 852 is 7 with a remainder of 276.
Use 7 as the next digit of our solution. 
Result so far: 91671.7
Subtracting 5964 from 6240 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 10:
When dividing 2760 by 852, we get 3 with a remainder of 204.
Use 3 as the next digit of our solution. 
Result so far: 91671.73
If we subtract 2556 from 2760, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
The number 852 fits into 2040 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 91671.732
Subtract 1704 from 2040 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
If we divide 3360 by 852, we get 3 and a remainder of 804.
Record the quotient 3 as the next digit in the result. 
Result so far: 91671.7323
Subtracting 2556 from 3360 leaves us with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Step 13:
8040 divided by 852 is 9 with a remainder of 372.
Record the quotient 9 as the next digit in the result. 
Result so far: 91671.73239
If we take 7668 away from 8040, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 14:
852 can be fit into 3720 4 times, resulting in a remainder of 312.
The number 4 becomes the next digit in our result. 
Result so far: 91671.732394
Deduct 3408 from 3720 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
If we divide 3120 by 852, we get 3 and a remainder of 564.
The next digit of our result is 3. 
Result so far: 91671.7323943
If we subtract 2556 from 3120, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 16:
The number 852 fits into 5640 6 times, leaving a remainder of 528.
Use 6 as the next digit of our solution. 
Result so far: 91671.73239436
Subtracting 5112 from 5640 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final outcome is 91671.73239436, with a leftover of 5.28e-07.
