10080053 ÷ 603 
We want to figure out the number of times 10080053 can be divided by 603.

Let's proceed to step 1:
1 divided by 603 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 603

On to step 2:
When dividing 10 by 603, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 603

Moving on to step 3:
603 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 100 after subtracting 0 from 100.
Bring next digit (8) of the dividend behind the 100 and repeat the process: 1008 / 603

On to step 4:
When dividing 1008 by 603, we get 1 with a remainder of 405.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 603 away from 1008, we end up with 405.
Include the next digit (0) from the dividend after 405, then repeat: 4050 / 603

Advancing to step 5:
When dividing 4050 by 603, we get 6 with a remainder of 432.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 3618 from 4050 leaves us with 432.
Grab the next digit (0) from the dividend, add it to 432, then carry on: 4320 / 603

Let's proceed to step 6:
If we divide 4320 by 603, we get 7 and a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtract 4221 from 4320 to get 99.
Bring next digit (5) of the dividend behind the 99 and repeat the process: 995 / 603

Moving on to step 7:
If we divide 995 by 603, we get 1 and a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 1671.0
Subtract 603 from 995 to get 392.
Take the next digit (3) from the dividend and append it to 392, then repeat: 3923 / 603

On to step 8:
The number 603 fits into 3923 6 times, leaving a remainder of 305.
The number 6 becomes the next digit in our result. 
Result so far: 16716.0
The remainder is 305 after subtracting 3618 from 3923.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
603 goes into 3050 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 16716.5
The remainder is 35 after subtracting 3015 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
603 goes into 350 0 times with a remainder of 350.
The next digit of our result is 0. 
Result so far: 16716.5
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
603 goes into 3500 5 times with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 16716.505
If we take 3015 away from 3500, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 12:
When dividing 4850 by 603, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 16716.5058
Subtracting 4824 from 4850 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
If we divide 260 by 603, we get 0 and a remainder of 260.
The next digit of our result is 0. 
Result so far: 16716.5058
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
603 goes into 2600 4 times with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 16716.505804
If we subtract 2412 from 2600, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 15:
The number 603 fits into 1880 3 times, leaving a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 16716.5058043
Subtracting 1809 from 1880 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 16:
603 goes into 710 1 times with a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 16716.50580431
The remainder is 107 after subtracting 603 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 16716.50580431 with a remaining 1.07e-07.
