123257 ÷ 66 
We want to figure out the number of times 123257 can be divided by 66.

Moving on to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 66

Moving on to step 2:
66 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 66

Advancing to step 3:
If we divide 123 by 66, we get 1 and a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 66 from 123 leaves us with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 66

Advancing to step 4:
572 divided by 66 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 528 from 572 leaves us with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 66

On to step 5:
If we divide 445 by 66, we get 6 and a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 186.0
Subtracting 396 from 445 leaves us with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 66

Let's proceed to step 6:
When dividing 497 by 66, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 1867.0
If we take 462 away from 497, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 66 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1867.5
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
66 goes into 200 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1867.53
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 66, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1867.53
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1867.5303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 66, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1867.5303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 66, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1867.530303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1867.530303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 66, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1867.53030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 1867.53030303 with a balance of 2e-09.
