87193 ÷ 66 
We're looking to find how many times 66 goes into 87193.

Step 1:
The number 66 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 66

Going ahead to step 2:
If we divide 87 by 66, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 87, we end up with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 66

Let's proceed to step 3:
66 can be fit into 211 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 198 from 211 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 66

Let's proceed to step 4:
66 goes into 139 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
The remainder is 7 after subtracting 132 from 139.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 66

Moving on to step 5:
73 divided by 66 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
Subtract 66 from 73 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
When dividing 70 by 66, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1321.1
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
66 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1321.1
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 66, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1321.106
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1321.106
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
66 can be fit into 400 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 1321.10606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1321.10606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
If we divide 400 by 66, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1321.1060606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 66, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1321.1060606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 1321.1060606, with a leftover of 4e-08.
