87603 ÷ 66 
Our goal is to divide 87603 by 66.

Let's proceed to step 1:
66 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 66

Going ahead to step 2:
When dividing 87 by 66, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we take 66 away from 87, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 66

Let's proceed to step 3:
216 divided by 66 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 198 from 216, we get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 66

Going ahead to step 4:
66 can be fit into 180 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 132.0
If we subtract 132 from 180, we get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 66

Advancing to step 5:
66 goes into 483 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 1327.0
Deduct 462 from 483 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 6:
66 can be fit into 210 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 1327.3
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
When dividing 120 by 66, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1327.31
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1327.318
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 66, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1327.3181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1327.31818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 1327.318181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 66, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1327.3181818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1327.31818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 1327.31818181, with a leftover of 5.4e-08.
