Let's divide 71286931 by 603
Let's see how many times 603 fits into 71286931.

Advancing to step 1:
603 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 603

Moving on to step 2:
603 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 603

Going ahead to step 3:
603 can be fit into 712 1 times, resulting in a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 603 from 712 and we're left with 109.
Take the next digit (8) from the dividend and append it to 109, then repeat: 1098 / 603

Step 4:
The number 603 fits into 1098 1 times, leaving a remainder of 495.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 603 from 1098 and we're left with 495.
Append the next digit (6) from the dividend to 495 and continue with: 4956 / 603

Advancing to step 5:
When dividing 4956 by 603, we get 8 with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 4824 from 4956 and we're left with 132.
Take the next digit (9) from the dividend and append it to 132, then repeat: 1329 / 603

Step 6:
When dividing 1329 by 603, we get 2 with a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
If we take 1206 away from 1329, we end up with 123.
Append the next digit (3) from the dividend to 123 and continue with: 1233 / 603

Moving on to step 7:
1233 divided by 603 is 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 11822.0
If we take 1206 away from 1233, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 603

Let's proceed to step 8:
When dividing 271 by 603, we get 0 with a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 118220.0
Subtracting 0 from 271 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
If we divide 2710 by 603, we get 4 and a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 118220.4
Deduct 2412 from 2710 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 10:
The number 603 fits into 2980 4 times, leaving a remainder of 568.
Use 4 as the next digit of our solution. 
Result so far: 118220.44
The remainder is 568 after subtracting 2412 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

After the division, we end up with 118220.44 and a remainder of 0.568.
