We're dividing 4002355 by 604 
We want to figure out the number of times 4002355 can be divided by 604.

Let's proceed to step 1:
If we divide 4 by 604, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 604

On to step 2:
40 divided by 604 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 604

On to step 3:
If we divide 400 by 604, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Include the next digit (2) from the dividend after 400, then repeat: 4002 / 604

Step 4:
604 goes into 4002 6 times with a remainder of 378.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 3624 from 4002, we get 378.
Take the next digit (3) from the dividend and append it to 378, then repeat: 3783 / 604

Step 5:
When dividing 3783 by 604, we get 6 with a remainder of 159.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 159 after subtracting 3624 from 3783.
Include the next digit (5) from the dividend after 159, then repeat: 1595 / 604

Going ahead to step 6:
604 can be fit into 1595 2 times, resulting in a remainder of 387.
Put 2 as the next digit of the answer. 
Result so far: 662.0
If we take 1208 away from 1595, we end up with 387.
Fetch the next digit (5) from the dividend, attach it to 387 and continue: 3875 / 604

Step 7:
3875 divided by 604 is 6 with a remainder of 251.
Put 6 as the next digit of the answer. 
Result so far: 6626.0
If we take 3624 away from 3875, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 8:
604 can be fit into 2510 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 6626.4
If we subtract 2416 from 2510, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
If we divide 940 by 604, we get 1 and a remainder of 336.
The next digit of our result is 1. 
Result so far: 6626.41
Deduct 604 from 940 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
When dividing 3360 by 604, we get 5 with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 6626.415
Subtracting 3020 from 3360 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
604 can be fit into 3400 5 times, resulting in a remainder of 380.
The next digit of our result is 5. 
Result so far: 6626.4155
The remainder is 380 after subtracting 3020 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 6626.4155, with a leftover of 0.0038.
