We look at the division of 45190078 by 604 
We want to divide 45190078 by 604.

Advancing to step 1:
4 divided by 604 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 604

Going ahead to step 2:
604 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 604

Let's proceed to step 3:
When dividing 451 by 604, we get 0 with a remainder of 451.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 451 leaves us with 451.
Include the next digit (9) from the dividend after 451, then repeat: 4519 / 604

On to step 4:
604 goes into 4519 7 times with a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4228 from 4519, we get 291.
Grab the next digit (0) from the dividend, add it to 291, then carry on: 2910 / 604

Moving on to step 5:
If we divide 2910 by 604, we get 4 and a remainder of 494.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 2416 from 2910 and we're left with 494.
Fetch the next digit (0) from the dividend, attach it to 494 and continue: 4940 / 604

On to step 6:
604 can be fit into 4940 8 times, resulting in a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 748.0
Subtract 4832 from 4940 to get 108.
Bring next digit (7) of the dividend behind the 108 and repeat the process: 1087 / 604

Going ahead to step 7:
604 can be fit into 1087 1 times, resulting in a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 7481.0
Subtract 604 from 1087 to get 483.
Fetch the next digit (8) from the dividend, attach it to 483 and continue: 4838 / 604

Let's proceed to step 8:
The number 604 fits into 4838 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 74818.0
If we subtract 4832 from 4838, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
604 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 74818.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
604 goes into 600 0 times with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 74818.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 74818.0, with a leftover of 0.6.
