We look at the division of 4142188 by 804 
We want to figure out the number of times 4142188 can be divided by 804.

Let's proceed to step 1:
804 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 804

Moving on to step 2:
804 goes into 41 0 times with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 804

Moving on to step 3:
414 divided by 804 is 0 with a remainder of 414.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 414 and we're left with 414.
Grab the next digit (2) from the dividend, add it to 414, then carry on: 4142 / 804

Step 4:
If we divide 4142 by 804, we get 5 and a remainder of 122.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4020 away from 4142, we end up with 122.
Include the next digit (1) from the dividend after 122, then repeat: 1221 / 804

Moving on to step 5:
1221 divided by 804 is 1 with a remainder of 417.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 804 from 1221 leaves us with 417.
Bring next digit (8) of the dividend behind the 417 and repeat the process: 4178 / 804

On to step 6:
When dividing 4178 by 804, we get 5 with a remainder of 158.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Subtract 4020 from 4178 to get 158.
Grab the next digit (8) from the dividend, add it to 158, then carry on: 1588 / 804

On to step 7:
804 can be fit into 1588 1 times, resulting in a remainder of 784.
Write down 1 as next digit of the result. 
Result so far: 5151.0
Subtract 804 from 1588 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 8:
804 can be fit into 7840 9 times, resulting in a remainder of 604.
The next digit of our result is 9. 
Result so far: 5151.9
Subtract 7236 from 7840 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 9:
The number 804 fits into 6040 7 times, leaving a remainder of 412.
The next digit of our result is 7. 
Result so far: 5151.97
If we take 5628 away from 6040, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 10:
The number 804 fits into 4120 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 5151.975
Subtract 4020 from 4120 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 804 fits into 1000 1 times, leaving a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 5151.9751
The remainder is 196 after subtracting 804 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
If we divide 1960 by 804, we get 2 and a remainder of 352.
The next digit of our result is 2. 
Result so far: 5151.97512
Subtracting 1608 from 1960 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 13:
3520 divided by 804 is 4 with a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 5151.975124
Subtracting 3216 from 3520 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 14:
804 can be fit into 3040 3 times, resulting in a remainder of 628.
Put 3 as the next digit of the answer. 
Result so far: 5151.9751243
If we take 2412 away from 3040, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 15:
If we divide 6280 by 804, we get 7 and a remainder of 652.
Write down 7 as next digit of the result. 
Result so far: 5151.97512437
Subtract 5628 from 6280 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final outcome is 5151.97512437, with a leftover of 6.52e-07.
