61091513 ÷ 603 
We want to divide 61091513 by 603.

Moving on to step 1:
The number 603 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 603

Moving on to step 2:
If we divide 61 by 603, we get 0 and a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 603

Advancing to step 3:
603 goes into 610 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 603 from 610 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 603

Step 4:
If we divide 79 by 603, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 79 to get 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 603

Moving on to step 5:
When dividing 791 by 603, we get 1 with a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 603 away from 791, we end up with 188.
Include the next digit (5) from the dividend after 188, then repeat: 1885 / 603

Advancing to step 6:
If we divide 1885 by 603, we get 3 and a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 1013.0
Subtracting 1809 from 1885 leaves us with 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 603

Going ahead to step 7:
The number 603 fits into 761 1 times, leaving a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 10131.0
The remainder is 158 after subtracting 603 from 761.
Include the next digit (3) from the dividend after 158, then repeat: 1583 / 603

Going ahead to step 8:
603 can be fit into 1583 2 times, resulting in a remainder of 377.
The next digit of our result is 2. 
Result so far: 101312.0
Subtract 1206 from 1583 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 9:
If we divide 3770 by 603, we get 6 and a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 101312.6
If we take 3618 away from 3770, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
The number 603 fits into 1520 2 times, leaving a remainder of 314.
Put 2 as the next digit of the answer. 
Result so far: 101312.62
Subtracting 1206 from 1520 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 11:
603 goes into 3140 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 101312.625
Subtracting 3015 from 3140 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
603 goes into 1250 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 101312.6252
The remainder is 44 after subtracting 1206 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
When dividing 440 by 603, we get 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 101312.6252
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
4400 divided by 603 is 7 with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 101312.625207
Deduct 4221 from 4400 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 15:
1790 divided by 603 is 2 with a remainder of 584.
The number 2 becomes the next digit in our result. 
Result so far: 101312.6252072
Subtract 1206 from 1790 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 16:
If we divide 5840 by 603, we get 9 and a remainder of 413.
Put 9 as the next digit of the answer. 
Result so far: 101312.62520729
Deduct 5427 from 5840 and we're left with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

The quotient of the division is 101312.62520729, and the remainder is 4.13e-07.
