We divide 11866706 by 603
We want to divide 11866706 by 603.

Step 1:
603 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 603

Step 2:
If we divide 11 by 603, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 603

Let's proceed to step 3:
The number 603 fits into 118 0 times, leaving a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 118 and we're left with 118.
Grab the next digit (6) from the dividend, add it to 118, then carry on: 1186 / 603

Step 4:
The number 603 fits into 1186 1 times, leaving a remainder of 583.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 603 from 1186 and we're left with 583.
Append the next digit (6) from the dividend to 583 and continue with: 5836 / 603

Moving on to step 5:
When dividing 5836 by 603, we get 9 with a remainder of 409.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 5427 away from 5836, we end up with 409.
Append the next digit (7) from the dividend to 409 and continue with: 4097 / 603

Step 6:
603 goes into 4097 6 times with a remainder of 479.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtract 3618 from 4097 to get 479.
Include the next digit (0) from the dividend after 479, then repeat: 4790 / 603

Advancing to step 7:
The number 603 fits into 4790 7 times, leaving a remainder of 569.
Use 7 as the next digit of our solution. 
Result so far: 1967.0
The remainder is 569 after subtracting 4221 from 4790.
Take the next digit (6) from the dividend and append it to 569, then repeat: 5696 / 603

Advancing to step 8:
If we divide 5696 by 603, we get 9 and a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 19679.0
The remainder is 269 after subtracting 5427 from 5696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 9:
2690 divided by 603 is 4 with a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 19679.4
If we subtract 2412 from 2690, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 10:
2780 divided by 603 is 4 with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 19679.44
Subtract 2412 from 2780 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 19679.44 with a remaining 0.368.
