Let's divide 42603001 by 204
We're looking to find how many times 204 goes into 42603001.

Going ahead to step 1:
204 goes into 4 0 times with 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.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 204

Advancing to step 2:
If we divide 42 by 204, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 204

Moving on to step 3:
204 can be fit into 426 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 408 from 426 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 204

On to step 4:
180 divided by 204 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 180 leaves us with 180.
Bring next digit (3) of the dividend behind the 180 and repeat the process: 1803 / 204

Step 5:
1803 divided by 204 is 8 with a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
If we take 1632 away from 1803, we end up with 171.
Take the next digit (0) from the dividend and append it to 171, then repeat: 1710 / 204

Let's proceed to step 6:
1710 divided by 204 is 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 2088.0
Deduct 1632 from 1710 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 204

Moving on to step 7:
When dividing 780 by 204, we get 3 with a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 20883.0
Subtract 612 from 780 to get 168.
Take the next digit (1) from the dividend and append it to 168, then repeat: 1681 / 204

On to step 8:
The number 204 fits into 1681 8 times, leaving a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 208838.0
If we subtract 1632 from 1681, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
204 goes into 490 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 208838.2
Subtracting 408 from 490 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
When dividing 820 by 204, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 208838.24
If we take 816 away from 820, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 204, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 208838.24
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
204 goes into 400 1 times with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 208838.2401
Deduct 204 from 400 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.

Going ahead to step 13:
204 can be fit into 1960 9 times, resulting in a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 208838.24019
Subtracting 1836 from 1960 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
204 can be fit into 1240 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 208838.240196
Subtract 1224 from 1240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
When dividing 160 by 204, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 208838.240196
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
The number 204 fits into 1600 7 times, leaving a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 208838.24019607
Deduct 1428 from 1600 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 208838.24019607 with a remainder of 1.72e-07.
