We're dividing 41938085 by 804 
The aim is to understand the frequency of 804 in 41938085.

On to step 1:
4 divided by 804 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 804

Step 2:
If we divide 41 by 804, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 804

Advancing to step 3:
If we divide 419 by 804, we get 0 and a remainder of 419.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 419 after subtracting 0 from 419.
Grab the next digit (3) from the dividend, add it to 419, then carry on: 4193 / 804

Moving on to step 4:
The number 804 fits into 4193 5 times, leaving a remainder of 173.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4020 away from 4193, we end up with 173.
Include the next digit (8) from the dividend after 173, then repeat: 1738 / 804

Let's proceed to step 5:
804 can be fit into 1738 2 times, resulting in a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 1608 from 1738, we get 130.
Grab the next digit (0) from the dividend, add it to 130, then carry on: 1300 / 804

On to step 6:
If we divide 1300 by 804, we get 1 and a remainder of 496.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
Deduct 804 from 1300 and we're left with 496.
Take the next digit (8) from the dividend and append it to 496, then repeat: 4968 / 804

Step 7:
The number 804 fits into 4968 6 times, leaving a remainder of 144.
The next digit of our result is 6. 
Result so far: 5216.0
Deduct 4824 from 4968 and we're left with 144.
Include the next digit (5) from the dividend after 144, then repeat: 1445 / 804

Moving on to step 8:
804 goes into 1445 1 times with a remainder of 641.
The number 1 becomes the next digit in our result. 
Result so far: 52161.0
If we take 804 away from 1445, we end up with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Going ahead to step 9:
If we divide 6410 by 804, we get 7 and a remainder of 782.
The number 7 becomes the next digit in our result. 
Result so far: 52161.7
Subtract 5628 from 6410 to get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Step 10:
When dividing 7820 by 804, we get 9 with a remainder of 584.
The number 9 becomes the next digit in our result. 
Result so far: 52161.79
If we subtract 7236 from 7820, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 11:
When dividing 5840 by 804, we get 7 with a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 52161.797
Subtract 5628 from 5840 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.

On to step 12:
2120 divided by 804 is 2 with a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 52161.7972
Subtract 1608 from 2120 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 13:
804 can be fit into 5120 6 times, resulting in a remainder of 296.
Record the quotient 6 as the next digit in the result. 
Result so far: 52161.79726
If we take 4824 away from 5120, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 14:
804 can be fit into 2960 3 times, resulting in a remainder of 548.
The number 3 becomes the next digit in our result. 
Result so far: 52161.797263
Subtract 2412 from 2960 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 15:
5480 divided by 804 is 6 with a remainder of 656.
The number 6 becomes the next digit in our result. 
Result so far: 52161.7972636
Subtracting 4824 from 5480 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 16:
If we divide 6560 by 804, we get 8 and a remainder of 128.
The next digit of our result is 8. 
Result so far: 52161.79726368
Deduct 6432 from 6560 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 52161.79726368, with a leftover of 1.28e-07.
