157188 ÷ 66 
We want to figure out the number of times 157188 can be divided by 66.

Going ahead to step 1:
1 divided by 66 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 66

Moving on to step 2:
66 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 66

Going ahead to step 3:
157 divided by 66 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 132 from 157 and we're left with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 66

Let's proceed to step 4:
66 goes into 251 3 times with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 53 after subtracting 198 from 251.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 66

On to step 5:
The number 66 fits into 538 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
If we subtract 528 from 538, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 66

On to step 6:
When dividing 108 by 66, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 2381.0
If we take 66 away from 108, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 66 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2381.6
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 2381.63
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 66, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 2381.636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 2381.6363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 66 fits into 420 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2381.63636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 2381.636363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
When dividing 420 by 66, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2381.6363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 2381.63636363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 2381.63636363, with a leftover of 4.2e-08.
