We look at the division of 7940213 by 604 
Let's see how many times 604 fits into 7940213.

Going ahead to step 1:
7 divided by 604 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 604

On to step 2:
If we divide 79 by 604, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 604

Going ahead to step 3:
If we divide 794 by 604, we get 1 and a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 604 from 794 and we're left with 190.
Fetch the next digit (0) from the dividend, attach it to 190 and continue: 1900 / 604

Going ahead to step 4:
604 goes into 1900 3 times with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1812 from 1900 to get 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 604

On to step 5:
If we divide 882 by 604, we get 1 and a remainder of 278.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 604 from 882 and we're left with 278.
Take the next digit (1) from the dividend and append it to 278, then repeat: 2781 / 604

Going ahead to step 6:
604 goes into 2781 4 times with a remainder of 365.
The next digit of our result is 4. 
Result so far: 1314.0
If we take 2416 away from 2781, we end up with 365.
Append the next digit (3) from the dividend to 365 and continue with: 3653 / 604

Let's proceed to step 7:
The number 604 fits into 3653 6 times, leaving a remainder of 29.
The next digit of our result is 6. 
Result so far: 13146.0
Subtracting 3624 from 3653 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
The number 604 fits into 290 0 times, leaving a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 13146.0
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 9:
2900 divided by 604 is 4 with a remainder of 484.
Record the quotient 4 as the next digit in the result. 
Result so far: 13146.04
Deduct 2416 from 2900 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 10:
If we divide 4840 by 604, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 13146.048
The remainder is 8 after subtracting 4832 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 604, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 13146.048
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
604 goes into 800 1 times with a remainder of 196.
The next digit of our result is 1. 
Result so far: 13146.04801
Deduct 604 from 800 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 13:
604 goes into 1960 3 times with a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 13146.048013
Subtract 1812 from 1960 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 14:
604 goes into 1480 2 times with a remainder of 272.
Use 2 as the next digit of our solution. 
Result so far: 13146.0480132
Subtract 1208 from 1480 to 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.

Step 15:
If we divide 2720 by 604, we get 4 and a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 13146.04801324
The remainder is 304 after subtracting 2416 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 13146.04801324 with a balance of 3.04e-07.
